Drinking will shorten your life, according to a study that suggests every glass of wine or pint of beer over the daily recommended limit will cut half an hour from the expected lifespan of a 40-year-old.

Those who think a glass of red wine every evening will help keep the heart healthy will be dismayed. The paper, published in the Lancet medical journal, says five standard 175ml glasses of wine or five pints a week is the upper safe limit – about 100g of alcohol, or 12.5 units in total. More than that raises the risk of stroke, fatal aneurysm (a ruptured artery in the chest), heart failure and death.

The risks for a 40-year-old of drinking over the recommended daily limit were comparable to smoking, said one leading scientist. “Above two units a day, the death rates steadily climb,” said David Spiegelhalter, Winton professor for the public understanding of risk at the University of Cambridge.

“The paper estimates a 40-year-old drinking four units a day above the guidelines [the equivalent of drinking three glasses of wine in a night] has roughly two years’ lower life expectancy, which is around a 20th of their remaining life. This works out at about an hour per day. So it’s as if each unit above guidelines is taking, on average, about 15 minutes of life, about the same as a cigarette.

“Of course, it’s up to individuals whether they think this is worthwhile.”

There is still a small benefit to drinking, which has been much flagged in the past. It does reduce the chance of a non-fatal heart attack. But, said Dr Angela Wood, from the University of Cambridge, lead author of the study, “this must be balanced against the higher risk associated with other serious – and potentially fatal – cardiovascular diseases.”

The big international study supports the new UK recommended limits of a maximum of 14 units a week for both men and women, which were fiercely contested when introduced by England’s chief medical officer, Dame Sally Davies, in 2016. Other countries with higher limits should reduce them, it suggests. They include Italy, Portugal and Spain as well as the US, where for men the recommended limit is almost double.

The study included data from nearly 600,000 current drinkers included in 83 studies carried out in 19 countries. About half the participants reported drinking more than 100g per week, and 8.4% drank more than 350g per week. Early deaths rose when more than 100g per week, which is five to six glasses of wine or pints of beer, was consumed.

A 40-year-old who drank up to twice that amount (100 to 200g) cut their life expectancy by six months. Between 200g and 350g a week, they lost one to two years of life, and those who drank more than 350g a week shortened their lives by four to five years.

Tim Chico, professor of cardiovascular medicine at the University of Sheffield, said smokers lost on average 10 years of life. “However, we think from previous evidence that it is likely that people drinking a lot more than 43 units are likely to lose even more life expectancy, and I would not be surprised if the heaviest drinkers lost as many years of life as a smoker.

“This study makes clear that on balance there are no health benefits from drinking alcohol, which is usually the case when things sound too good to be true.”

Spiegelhalter said it was “a massive and very impressive study. It estimates that, compared to those who only drink a little, people who drink at the current UK guidelines suffer no overall harm in terms of death rates, and have 20% fewer heart attacks.”

Prof Jeremy Pearson, associate medical director at the British Heart Foundation, which part-funded the study, called it “a serious wakeup call for many countries.”

Dr Tony Rao, visiting lecturer in old age psychiatry at King’s College London, said the study “highlights the need to reduce alcohol related harm in baby boomers, an age group currently at highest risk of rising alcohol misuse”. It did not take into account the possibility of mental disorders such as dementia, which could accompany the other health problems drinkers incur.

In a commentary in the Lancet, Profs Jason Connor and Wayne Hall from the University of Queensland Centre for Youth Substance Abuse Research in Australia, anticipated that the suggestion of lowering recommended drinking limits will come up against opposition.

“The drinking levels recommended in this study will no doubt be described as implausible and impracticable by the alcohol industry and other opponents of public health warnings on alcohol. Nonetheless, the findings ought to be widely disseminated and they should provoke informed public and professional debate.”

Research published in The Lancet Public Health indicated that alcohol use disorder is a major risk factor for dementia, especially early-onset dementia.

“The relationships between alcohol use and cognitive health in general, and dementia in particular, are complex,” Michaël Schwarzinger, MD, of the Translational Health Economics Network, France, and colleagues wrote. “Moderate drinking has been consistently associated with detrimental effects on brain structure, and nearly every review describes methodological problems of underlying studies, such as inconsistent measurement of alcohol use or dementia, or both, and insufficient control of potential confounders. By contrast, heavy drinking seems detrimentally related to dementia risk, whatever the dementia type.”

To determine how alcohol use disorders effect dementia risk, especially among those aged younger than 65 years, researchers conducted a nationwide retrospective cohort of hospitalized adults in France discharged with alcohol-related brain damage, vascular dementia or other dementias between 2008 and 2013. Alcohol use disorder was the primary exposure, and dementia was the main outcome. Using the French National Hospital Discharge database, they studied the prevalence of early-onset dementia and determined whether alcohol use disorders or other risk factors were associated with dementia onset.

In total, 1,109,343 adults discharged from hospital in France were diagnosed with dementia and included in the study. Of those, 35,034 cases of dementia were attributable to alcohol-related brain damage, and 52,625 cases had other alcohol use disorders. Among the 57,353 early-onset dementia cases, 22,338 (38.9%) were attributable to alcohol-related brain damage and 10,115 (17.6%) had an additional diagnosis of alcohol use disorders.

Analysis revealed that alcohol use disorders were linked to a threefold increased risk for all types of dementia and “were the strongest modifiable risk factor for dementia onset” (adjusted HR = 3.34 [95% CI, 3.28–3.41] for women; HR = 3.36 [95% CI, 3.31–3.41] for men). Alcohol use disorders remained associated with an increased risk for vascular and other dementias even after excluding alcohol-related brain damage, according to the findings. Furthermore, chronic heavy drinking was also linked to all other independent risk factors for dementia onset, including tobacco smoking, high blood pressure, diabetes, lower education, depression and hearing loss.

“Our findings suggest that the burden of dementia attributable to alcohol use disorders is much larger than previously thought, suggesting that heavy drinking should be recognized as a major risk factor for all types of dementia,” Schwarzinger said in a press release. “A variety of measures are needed, such as reducing availability, increasing taxation and banning advertising and marketing of alcohol, alongside early detection and treatment of alcohol use disorders.”

Previous research has largely focused on modest alcohol use, and its possible beneficial effect, thus overlooking the effect of heavy alcohol use as a modifiable risk factor for dementia, according to a related comment written by Clive Ballard, MBChB, MRCPsych, and Iain Lang, PhD, of the University of Exeter Medical School, U.K.

“Although many questions remain, several can be answered using existing data, which would provide an opportunity to refine our understanding of the pathways of modifiable risk and develop optimal prevention strategies,” Ballard and Lang wrote. “In our view, this evidence is robust, and we should move forward with clear public health messages about the relationship between both alcohol use disorders and alcohol consumption, respectively, and dementia.” – by Savannah Demko

Kent Hutchinson of the CU Change Lab is one of authors of this new research on the effects of Marijuana on the brain.

by Cay Leytham-Powell

Marijuana may not be as damaging to the brain as previously thought, according to new research from the University of Colorado Boulder and the CU Change Lab.

The research, which was published in the journal Addiction, examined the brains of more than 1,000 participants of varying ages, and found that long-term alcohol use is much more damaging to the brain than marijuana, contradicting years of research into the effects of marijuana and other cannabinoid products on the brain.

These findings, and other conclusions suggesting the potential public health benefits of marijuana, come amid the recent back-and-forth on federal marijuana policy and the nation’s opioid crisis.

Yet scientists are still hesitant to say that cannabinoid usage, specifically as it pertains to marijuana and its associated products, is beneficial.

“Particularly with marijuana use, there is still so much that we don’t know about how it impacts the brain,” said Rachel Thayer, a graduate student in clinical psychology at CU Boulder and the lead author of the study. “Research is still very limited in terms of whether marijuana use is harmful, or beneficial, to the brain.”

While the negative effects of alcohol on the brain have been known by researchers for years, it has been assumed that cannabinoids are as damaging to long-term brain health—if not more—given the immediate psychoactive effects of the THC (the chemical that gets a person high) in marijuana.

However, this may not necessarily be true.

“When you look at the research much more closely, you see that a lot of it is probably not accurate,” said study co-author Kent Hutchison, a professor of behavioral neuroscience at CU Boulder and co-director of the CU Change Lab, which explores the factors linked with health and risk behavior.

“When you look at these studies going back years, you see that one study will report that marijuana use is related to a reduction in the volume of the hippocampus. The next study then comes around, and they say that marijuana use is related to changes in the cerebellum or the whatever.”

“The point is that there’s no consistency across all of these studies in terms of the actual brain structures.”

To combat this misconception in the existing literature, the researchers gave a fresh look at some existing neurological imaging data from the MRIs of both adolescents and adults to see how, using the same variables and controls, the influence of cannabinoids on the brain compared to or contrasted with alcohol.
“With alcohol, we’ve known it’s bad for the brain for decades,” said Hutchison. “But for cannabis, we know so little.”

To see any potential difference, the researchers used the data to examine the most important neurological components: gray matter and white matter.

Gray and white matter are the two main types of tissue that make up the brain and central nervous system. Gray matter is the “stuff”—the cell bodies, dendrites and axon terminals—that enable functionality. White matter, then, is how the grey matter communicates between clusters. Any loss of size or integrity in either can make the brain not work quite like it should.

The study found that alcohol use was significantly associated with a decrease in gray matter size and white matter integrity, particularly for adults who may have decades of exposure. Marijuana and associated cannabinoid products, on the other hand, were not shown to have any long-term impact on the amount of gray matter in the brain or on the integrity of the white matter.

The research demonstrated that, “while marijuana may also have some negative consequences, it definitely is nowhere near the negative consequences of alcohol,” according to Hutchison.

Despite marijuana not being as harmful as once thought, and definitely not as damaging as other legal and illegal products, the research has not yet proved any possible benefits. This is particularly the case as it relates to the different products on the market (both THC and non-THC-containing cannabinoid products), their usage with pain and addiction treatment and the effect on different ages — especially as cannabinoid usage is on the rise among older populations.

“Considering how much is happening in the real world with the legalization movement, we still have a lot of work to do,” Hutchison said.

Individuals with major depressive disorder (MDD) have double the risk of alcohol use disorders (AUDs) and vice versa, and it has previously been proposed that some people with MDD may use alcohol to self-medicate. Though alcohol can become depressant if used chronically, alcohol initially has an antidepressant effect, though the underlying mechanisms have not been identified. Findings reported in September 2016 in Nature Communications begin to elucidate the basis of this action.

Behavioral and molecular evidence of the rapid antidepressant activity of NMDA receptor (NMDAR) antagonists, which have been found to be effective within 2 hours of administration and remain so for 2 weeks, represents a significant advance in depression treatment. Antidepressant efficacy involves the induction phase and the sustained phase.

The sustained phase of rapid antidepressants requires “both new protein synthesis and an increase in protein stability… for the GABABR shift in function necessary to increase” the activity of mTORC1, a mechanistic target of rapamycin complex 1, the authors explained in their paper. Rapamycin (mTOR) is a “serine/threonine kinase essential for messenger RNA translation” and is required for the sustained impact of rapid antidepressants.

Citing previous findings that ethanol (EtOH) also blocks NMDARs in the hippocampus, scientists at the University of Texas at Austin and Wake Forest University School of Medicine in Winston-Salem, North Carolina, aimed to determine whether EtOH and NMDAR antagonists exert rapid antidepressant effects via the same synaptic pathways in rodents. They hypothesized that EtOH “has lasting antidepressant efficacy, shares the same downstream molecular signaling events as rapid antidepressants, and requires de novo protein synthesis.”

First, they found that acute exposure to EtOH led to antidepressant and anxiolytic behaviors in rodents for up to 24 hours. They then discovered that, like NMDAR antagonists, EtOH alters the expression and signaling of GABABR, increases dendritic calcium, and leads to the synthesis of new GABABRs. This synthesis requires fragile-X mental retardation protein (FMRP), an RNA-binding protein of which precise levels are needed for normal neuronal functioning.

The antidepressant effects and the changes in GABABR expression and dendritic calcium were not observed in in Fmr1-knockout (KO) mice, supporting the concept that FMRP has in important role in regulating protein synthesis after EtOH exposure, and thereby facilitating its antidepressant efficacy.

These results point to a shared molecular pathway for the antidepressant activity of EtOH and rapid antidepressants, and highlight a mechanism involved in the initial antidepressant action of alcohol. “A shift in GABABR signaling is observed with both rapid antidepressants and acute EtOH treatment, which may provide insight into the molecular basis for the high comorbidity between major depressive disorder and AUD,” the authors concluded.

A new type of synthetic alcohol has been discovered which could allow people to enjoy the sociable effects of a few pints, but skip the hangover that usually follows.

The new drink, known as ‘alcosynth’, is designed to mimic the positive effects of alcohol but doesn’t cause a dry mouth, nausea and a throbbing head, according to its creator Professor David Nutt.

The Imperial College Professor and former government drugs advisor told The Independent he has patented around 90 different alcosynth compounds.

Two of them are now being rigorously tested for widespread use, he said – and by 2050, he hopes alcosynth could completely replace normal alcohol.

“It will be there alongside the scotch and the gin, they’ll dispense the alcosynth into your cocktail and then you’ll have the pleasure without damaging your liver and your heart,” he said.

“They go very nicely into mojitos. They even go into something as clear as a Tom Collins. One is pretty tasteless, the other has a bitter taste.”

By researching substances that work on the brain in a similar way to alcohol, Professor Nutt and his team have been able to design a drug which they say is non-toxic and replicates the positive effects of alcohol.

“We know a lot about the brain science of alcohol; it’s become very well understood in the last 30 years,” said Professor Nutt.

“So we know where the good effects of alcohol are mediated in the brain, and can mimic them. And by not touching the bad areas, we don’t have the bad effects.”

Advocates of alcosynth believe it could revolutionise public health by relieving the burden of alcohol on the health service.

According to Alcohol Concern, drinking is the third biggest risk factor for disease and death in the UK, after smoking and obesity.

“People want healthier drinks,” said Professor Nutt. “The drinks industry knows that by 2050 alcohol will be gone.”

“They know that and have been planning for this for at least 10 years. But they don’t want to rush into it, because they’re making so much money from conventional alcohol.”

Early experiments into alcosynth, such as those reported on by BBC’s Horizon in 2011, used a derivative of benzodiazepine – the same class of drugs as Valium.

Mr Nutt said his new drinks did not contain benzodiazepine, and their formulas would remain a closely guarded, patented secret.

However, the huge cost of funding research into the drug and regulatory concerns mean it could be a long time before people can order an alcosynth cocktail at their local pub.

Professor Nutt, who was sacked from his position as the government drugs tsar in 2009 after he claimed taking ecstasy was less dangerous than riding a horse, said he was unsure if the use of synthetic alcohol would be restricted by the new Psychoactive Substances Act, which came into force in May.

“It’s an interesting idea, but too much in its infancy at the moment for us to comment on,” a Department of Health spokesperson told The Independent.

“I don’t think we’d give money to it until it was a little further along,” said the spokesperson. “If [Professor Nutt] were to apply for funding, it would go through the process of everything else and would be judged on its merits.”

“It would be great for producing better workforce efficiency if no one was hungover,” they added.

According to Professor Nutt, the effects of alcosynth last around a couple of hours – the same as traditional alcohol.

He said he and his team have also managed to limit the effects of drinking a lot of alcosynth, so in theory it would be impossible to ever feel too ‘drunk’.

“We think the effects round out at about four or five ‘drinks’, then the effect would max out,” he said.

“We haven’t tested it to destruction yet, but it’s safer than drinking too much alcohol. With clever pharmacology, you can limit and put a ceiling on the effects, so you can’t ever get as ill or kill yourself, unlike with drinking a lot of vodka.”

Researcher Guy Bentley worked with Professor Nutt on a new report by the liberal think tank the Adam Smith Institute into alcosynth regulation.

Mr Bentley told The Independent he hoped to persuade the government to accept the drug as a way of reducing the harm caused by alcohol.

“[The report] is trying to spark what happened with e-cigarettes and tobacco, but with alcohol,” he said. “Professor Nutt has been experimenting on this for a long time, but I thought to myself – ‘where is it?’ I wanted my hangover-free booze.”

However, not everyone was as keen on the new discovery.

Neil Williams, from the British Beer and Pub Association, said alcosynth was not necessary, as “there are other ways of avoiding a hangover”.

“There are plenty of low-strength drinks, particularly beers,” he told The Independent. “We should all drink in moderation so we shouldn’t need to have a hangover anyway.”

“I’d want to know more about it before I tried it myself,” he said.

As acceptance of and usage of marijuana have become more widespread, a whole lot of interesting questions for public health researchers have been raised: How will legal marijuana affect our children? Our jobs? Our relationships?

Or how about our sex lives?

That latter question inspired a research project by Joseph Palamar and his colleagues at New York University. “Since the landscape is changing, and marijuana continues to increase in popularity, research is needed to continue to examine if and how marijuana use may influence risk for unsafe sexual behavior,” they write in the July issue of the journal Archives of Sexual Behavior.

To that end, Mr. Palamar and his colleagues recruited 24 heterosexual adults to take part in a series of in-depth interviews about prior sexual experiences that happened under the influence of either alcohol or marijuana. This was not meant to be a national sample. Rather, the purpose was to obtain a rigorous qualitative assessment of the different effects of alcohol and marijuana on people’s sexual behaviors and to use this as a jumping-off point for future quantitative research.

Here are a few of the observations the researchers drew from the interviews.

1. Beer goggles are real.

Respondents “overwhelmingly reported that alcohol use was more likely to [negatively] affect the partners they chose,” the study found. Both men and women were fairly likely to say that alcohol had the effect of lowering their standards for whom they slept with, in terms of character and appearance. With marijuana, this seemed to be much less of an issue.

“With weed I know who I’m waking up with. With drinking, you don’t know. Once you start drinking, everybody looks good,” a 34-year-old female said.

Marijuana use also was more associated with sex with people the respondents already knew — girlfriends and boyfriends, for instance. But alcohol “was commonly discussed in terms of having sex with strangers [or someone new],” the study found.

2. Drunk sex often leads to regret. Stoned sex typically doesn’t.

“The most commonly reported feeling after sex on alcohol was regret,” the study found. “Both males and females commonly reported that regret, shame, and embarrassment were associated with alcohol use, but this was rarely reported for marijuana.”

“I want to cook the person something to eat [after sex] when I’m high,” one male respondent said. “When I’m drunk, it’s like, ‘I’m out of here.’ Or get away from me.”

These negative emotions are seen as at least partly due to drunk sex being associated more with strangers.

3. Drunk sex can make you sick. Stoned sex can make you distracted.

“Nausea, dizziness, feeling sick [and vomiting], and blacking out were commonly reported to be associated with alcohol use,” the study found. One male said he accidentally fell asleep during sex while drunk. Another told of multiple instances where sex had to be interrupted because “I’ve had to stop and go hurl.”

There were fewer adverse effects reported with marijuana, and these tended to be more mental. One respondent said that marijuana use lessened his motivation to have sex. Another reported that being high distracted her from the experience.

“You’re so high [on marijuana] … you start thinking sex is weird. ‘What is sex?’ ” a female respondent reported.

4. The pleasure is usually better on marijuana.

The study found that “alcohol tended to numb sensations and marijuana tended to enhance sensations.”

“Alcohol tends to be a lot more numb,” a male respondent said. “Everything is sort of blunted and muted, whereas with marijuana it’s intensified.”

This “numbness” was associated with a longer duration of sex while drunk. But that wasn’t necessarily a good thing.

It “sometimes lasts too long,” one female respondent said. “Compared to when you’re high — it feels so great and it might be a little shorter.”

The study found that both men and women reported longer and more intense orgasms on marijuana, with one woman reporting hers were “magnified at least by five times.”

Also, marijuana led to “more tender, slow, and compassionate sexual acts, and to involve more sensation and sensuality than alcohol,” the report found.

5. Drunk sex is riskier overall.

“With regard to sexual risk behavior, the majority of participants felt that alcohol was riskier, sexually, than marijuana,” Mr. Palamar and his colleagues found. People typically said they exercised poorer judgment when drunk than when stoned, and were more likely to black out and forget whom they were with, what they were doing or whether they used protection.

Participants generally didn’t note this type of behavior with marijuana and said that while under its effects, they felt more in control overall. “One participant interestingly pointed out that marijuana use decreased his likelihood of engaging in risk behavior because while high he was too paranoid to give in,” the study found.

There were some take-homes viewed as useful from a public health perspective. First, the findings confirm one thing that numerous other studies have shown: Alcohol use seems to be closely associated with high-risk sexual behavior.

Aside from the link with unprotected sex and the corresponding risk of unexpected pregnancy or sexually transmitted diseases, studies have also drawn disturbing parallels between alcohol use and sexual assault. That link appeared even in the very small sample in Mr. Palamar’s study: One out of the 12 women interviewed reported an instance of sexual assault while under the effects of alcohol.

These negative consequences appear to be less pronounced with marijuana. Research found significantly lower incidences of domestic violence among couples who smoke marijuana, for instance.

You may have seen articles like “the 23 Types of Drunk People You See on a Night Out,” but can changes to personality traits linked to intoxication from alcohol consumption be empirically categorized? A study in the journal Addiction Research & Theory sought to use the Five-Factor Model of personality as a framework to describe variations in “drunk personality,” identify clusters of personalities, and assess how cluster membership is linked to alcohol-related harms.

A total of 187 undergraduate “drinking buddy” pairs (mean age 18.4) were recruited for the study in which participants completed a survey on demographics, alcohol consumption patterns, alcohol-related consequences (measured with the Young Adult Alcohol Problems Screening Test), and a 50-item scale from Goldberg’s International Personality Item Pool on their own behavior when sober, behavior when drunk, their friend’s behavior when sober, and their friend’s behavior while intoxicated.

Four clusters were identified:

1.Hemingway

•This was the largest group; only slight changes in behavior were reported when intoxicated
•This group decreased less in Conscientiousness (being prepared, organized, prompt) and Intellect (being imaginative, understanding abstract ideas) than the other groups
•Not associated with experiencing more alcohol-related consequences
•Encapsulates the majority of drinkers that do not undergo drastic changes or experience harm while drinking

2. Mr. Hyde

•This group had larger than average alcohol-related decreases in Conscientiousness, Intellect, and Agreeableness
•Compared to the other groups, this group tended to be less intellectual, more hostile, and less responsible under the influence of alcohol compared to when they are sober
•Only group that was statistically more likely to have alcohol consequences, indicating that they are more likely to incur acute harm (memory blackout, being arrested for drunken behavior) and have less pleasing personality characteristics when they drink

3. Mary Poppins

•14% of the sample were classified in this group
•When sober this group is highly Agreeable; when intoxicated, this group decreases less than average in Conscientiousness, Intellect, and Agreeableness
•This group reported fewer alcohol consequences overall compared to the Mr. Hyde group
•Considered the sweet, responsible drinkers who experience less alcohol-related problems versus those that are most affected

4. The Nutty Professor

•This group tended to be introverted when sober but showed an increase in Extraversion and decrease in Conscientiousness when drunk
•Compared to the other groups, this cluster had the biggest discrepancy between reported sober and drunk five-factor model traits
•However, this group was not associated with having experienced more alcohol-related consequences
•While the personality change for this group was most dramatic, this cluster was not associated with increased harm, possibly due to the fact that the mean drunk levels for these traits, while different from their sober levels, were still within normal range

Conclusions

This is the first empirical investigation into unique personality changes due to intoxication from alcohol consumption. While not all personality types had a risk of experiencing negative consequences from drinking, tempering alcohol consumption is advised for anyone regardless of “drunk personality.”
