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.

Marijuana may give relief to migraine sufferers, according to research published online in Pharmacotherapy.

The research included 121 patients diagnosed with migraines and treated with medical marijuana between January 2010 and September 2014. Patients in the study used both inhaled marijuana and edible marijuana. The researchers said inhaled marijuana seemed to be preferred for treating current headaches, and edibles seemed to be favored for headache prevention.

The researchers found that 103 study participants said they had a decrease in their monthly migraines. Fifteen patients said they had the same number of migraines, and 3 reported an increase in headaches. Overall, the patients’ number of migraines fell from 10.4 to 4.6 per month, which is statistically and clinically significant.

“There was a substantial improvement for patients in their ability to function and feel better,” senior author Laura Borgelt, PharmD, a professor in the School of Pharmacy and Pharmaceutical Sciences at the University of Colorado Anschutz Medical Campus in Aurora, said in a university news release. “Like any drug, marijuana has potential benefits and potential risks. It’s important for people to be aware that using medical marijuana can also have adverse effects.”

Maya Donnelly awoke to what sounded like thunder in the early morning hours, but dismissed it as a typical monsoon storm and went back to sleep. Later that morning, she looked in the carport at her home in Nogales, near the US-Mexico border, and saw pieces of wood on the ground.

She found a bulky bundle wrapped in black plastic. Inside was roughly 26lbs of marijuana – a package that authorities say was worth $10,000 and was likely dropped there accidentally by a drug smuggler’s aircraft.

Police are now trying to determine whether the bundle was transported by an aircraft or a pilotless drone. Such runs usually occur at night.

“It’s all right on top of our dog’s house,” Donnelly said of the incident, which occurred on 8 September and was first reported by the Nogales International newspaper. “It just made a perfectly round hole through our carport.”

Living near the border, Donnelly said she assumed the object contained drugs. She immediately called her husband, Bill, who told her to call 911. The couple said officers who responded told them an ultralight aircraft smuggling marijuana from Mexico had probably let part of its load go early by accident before dropping the rest farther north, the newspaper reported.

Nogales police chief Derek Arnson said it was the first time in his three-year tenure that he had seen a load of drugs hit a building.

“Someone definitely made a mistake, and who knows what the outcome of that mistake might be for them,” Arnson said.

Maya Donnelly said she thought it unlikely someone would come looking for the drugs, which are now in police custody. Arnson agreed but said police had boosted patrols in the neighbourhood.

The family will have to pay the estimated $500 in repairs, as well as pay for a new home for their German Shepherd, Hulk. But the scenario could have been much worse for the couple and their three teenage daughters.

“Where it landed was clear on the other side of the house from the bedrooms,” Maya Donnelly said. “We were lucky in that sense.”

Friends and family also have gotten a laugh. Several joked that the couple could have profited from the surprise package.

“That’s what everybody says: ‘Why did you call 911?”’ Maya Donnelly said. “But how can you have a clear conscience, right? We could have made lots of home repairs with that.”

An assortment of edible marijuana products. Most edibles in a recent study inaccurately described the amount of THC on their labels.

By CATHERINE SAINT LOUIS

An analysis of 75 edible marijuana products sold to patients in Seattle, San Francisco and Los Angeles found that labels on just 17 percent accurately described their levels of THC, the main psychoactive ingredient, researchers reported Tuesday.

Sixty percent of the products had less THC than their packages advertised, and 23 percent of them had more THC than claimed.

“We need a more accurate picture of what’s being offered to patients,” said Dr. Donald Abrams, the chief of hematology and oncology at San Francisco General Hospital. He was not involved in the new study, which was published in JAMA.

“What we have now in this country is an unregulated medical marijuana industry, due to conflicts between state and federal laws,” Dr. Abrams said.

After ingesting marijuana, patients experience the maximal high one to three hours later. (It is felt within minutes after smoking.) Inaccurate labels complicate the consumption of marijuana for medical purposes.

Products with too little THC, or tetrahydrocannabinol, may fail to deliver symptom relief to those with debilitating conditions like chronic pain, and those with too much may overwhelm users.

Some of Dr. Abrams’s older cancer patients have tried edibles, he said, because they do not want to smoke marijuana. But some have eaten too much THC, with unpleasant results such as severe anxiety.

In the new study, cannabis candy, drinks and baked goods from 47 brands were tested by the Werc Shop, a laboratory with outposts in California and Washington State.

The Johns Hopkins University School of Medicine paid for the study except for the cost of the testing, which was covered by the Werc Shop. The company’s chief executive, Jeffrey Raber, is a study author.

Some discrepancies were notably large: In one case, a product had just three milligrams of THC even though its label claimed 108, said Ryan Vandrey, the study’s lead author and an associate professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine.

The researchers declined to name specific manufacturers or products. “I didn’t want to get sued,” Dr. Vandrey said.

“The point is not to say, ‘Hey, X medical marijuana company, you’re bad,’ ” he added. The more serious issue is that “we don’t have the kind of quality assurance for edibles that we have for any other medicine.”

The analysis found some geographical differences: The likelihood of having edible medical marijuana with more THC than advertised was higher in Los Angeles, while the likelihood of having it with less THC than labeled was greater in Seattle.

The researchers also tested each product for cannabidiol, or CBD, a nonpsychoactive ingredient of marijuana that is being studied in purified form as a possible aid to children with intractable epilepsy.

Forty-four products had detectable levels of CBD, though only 13 disclosed CBD. Nine had less CBD than labeled; four had more.

One limitation was that just one laboratory performed the analysis, medical and lab experts cautioned. Methodologies and results vary from lab to lab.

Some variability in test results is routine in this sort of analysis, so the researchers classified labels as accurate if the THC content was within 10 percent of the claimed levels.

Still, Remy Kachadourian, a chemist who has analyzed edible marijuana, suggested that 10 percent variability was too narrow.

“Plus or minus 15 percent is acceptable, and not only in my lab, but other labs in Colorado,” said Dr. Kachadourian, a senior scientist at CMT Laboratories in Denver.

Even though 23 states and the District of Columbia have medical marijuana programs, the federal government does not recognize marijuana as medicine and considers it illegal.

“When that changes,” Dr. Abrams said, “we’ll see the industry rushing to standardize dosing, as well as laboratory testing of products.”

The Drug Enforcement Administration has been impeding and ignoring the science on marijuana and other drugs for more than four decades, according to a report released this week by the Drug Policy Alliance, a drug policy reform group, and the Multidisciplinary Association for Psychedelic Studies, a marijuana research organization.

“The DEA is a police and propaganda agency,” Ethan Nadelmann, executive director of the Drug Policy Alliance, said Wednesday. “It makes no sense for it to be in charge of federal decisions involving scientific research and medical practice.”

The report alleges that the DEA has repeatedly failed to act in a timely fashion when faced with petitions to reschedule marijuana. The drug is currently classified as Schedule I, which the DEA reserves for the “most dangerous” drugs with “no currently accepted medical use.” Schedule I drugs, which include substances like heroin and LSD, cannot receive federal funding for research. On three separate occasions — in 1973, 1995 and again in 2002 — the DEA took years to make a final decision about a rescheduling petition, and in two of the cases the DEA was sued multiple times to force a decision.

The report criticizes the DEA for overruling its own officials charged with determining how illicit substances should be scheduled. It also criticizes the agency for creating a “regulatory Catch-22” by arguing there is not enough scientific evidence to support rescheduling marijuana while simultaneously impeding the research that would produce such evidence.

A spokesperson at the DEA declined to comment on the report.

The feds have long been accused of only funding marijuana research that focuses on the potential negative effects of the substance, but that trend appears to be changing.

According to The Hill, the National Institute on Drug Abuse has conducted about 30 studies to date on the potential benefits of marijuana. NIDA oversees the cultivation, production and distribution of marijuana grown for research purposes at the University of Mississippi in the only federally legal marijuana garden in the U.S.– a process through which the only federally sanctioned marijuana studies are approved.

The joint report comes less than two weeks after the House approved three amendments taking aim at the DEA and its ability to enforce federal marijuana and hemp laws in states which have legal marijuana operations and industrial hemp programs. The medical marijuana amendment was sponsored by Rep. Dana Rohrabacher (R-Calif.).

“Nobody should be afraid of the truth,” Rohrabacher said Wednesday. “There’s a lot of other drugs that have harmful side effects. Is the downside of marijuana a harmful side effect? Or is there a positive side that actually does help? That needs to be proven.”

The federal government’s interest in marijuana certainly appears to be growing. Since 2003, it has approved more than 500 grants for marijuana-related studies, with a marked upswing in recent years, according to McClatchy. In 2003, 22 grants totaling $6 million were approved for cannabis research. In 2012, that number had risen to 69 approved grants totaling more than $30 million.

“The DEA has obstructed research into the medical use of marijuana for over 40 years and in the process has caused immeasurably suffering that would otherwise have been treated by low-cost, low-risk generic marijuana,” Rick Doblin, executive director of the Multidisciplinary Association for Psychedelic Studies, said in a statement. “The DEA’s obstruction of the FDA approval process for marijuana has — to the DEA’s dismay — unintentionally catalyzed state-level medical marijuana reforms.”

Currently, 22 states and the District of Columbia have legalized marijuana for medical use. Eight other states — Alabama, Iowa, Kentucky, Mississippi, South Carolina, Tennessee, Utah and Wisconsin — have legalized CBD oils, made from a non-psychoactive ingredient in marijuana frequently used to treat epilepsy, for limited medical use or for research purposes.

A number of recent studies have shown the medical potential of cannabis. Purified forms may attack some forms of aggressive cancer. Marijuana use also has been tied to better blood sugar control and may help slow the spread of HIV. One study found that legalization of the plant for medical purposes may even lead to lower suicide rates.

Nadelmann said the DEA has “demonstrated a regular pattern of abusing its discretionary powers.”

“We believe this authority would be better handled by another government agency in the health realm, or even better still, by an organization that is truly independent, perhaps something that involves the National Academy of Sciences,” he said. “We will be working to encourage greater congressional oversight and also to call for reforms of federal law.”

Humans have been ingesting mind-altering substances for a very long time. Hallucinogen-huffing bowls 2,500 years old (http://www.livescience.com/5240-ancient-family-heirlooms-snort-hallucinogens.html) have been found on islands in the Lesser Antilles, and traditional cultures from the Americas to Africa use hallucinogenic substances for spiritual purposes. Here are some notable substances that send the mind tripping.

LSD is commonly known as “acid,” but its scientific name is a mouthful: lysergic acid diethylamaide. The drug was first synthesized in 1938 from a chemical called ergotamine. Ergotamine, in turn, is produced by a grain fungus that grow on rye.

LSD was originally produced by a pharmaceutical company under the name Delysid, but it got a bad reputation in the 1950s when the CIA decided to research its effects on mind control. The test subjects of the CIA project MKULTRA proved very difficult to control indeed, and many, like counter-culture writer Ken Kesey, started taking the drug for fun (and for their own form of 1960s enlightenment).

ayahuasca-vine-110929

Ayahuasca is a hallucinatory mixture of Amazonian infusions centered around the Banisteriopsis caapi vine. The brew has long been used by native South American tribes for spiritual rituals and healing, and like other hallucinogens, ayahuasca often triggers very intense emotional experiences (vomiting is also common). In 2006, National Geographic writer Kira Salak described her experience with ayahuasca in Peru for the magazine.

” I will never forget what it was like. The overwhelming misery. The certainty of never-ending suffering. No one to help you, no way to escape. Everywhere I looked: darkness so thick that the idea of light seemed inconceivable,” Salak wrote. “Suddenly, I swirled down a tunnel of fire, wailing figures calling out to me in agony, begging me to save them. Others tried to terrorize me. ‘You will never leave here,’ they said. ‘Never. Never.'”

Nonetheless, Salak wrote, when she broke free of her hallucinations, her crippling depression was alleviated. It’s anecdotal experiences like this that have led researchers to investigate the uses of hallucinogens as therapy for mental disorders such as anxiety, depression and post-traumatic stress disorder.

Peyote is a cactus that gets its hallucinatory power from mescaline. Like most hallucinogens, mescaline binds to serotonin receptors in the brain, producing heightened sensations and kaleidoscopic visions.

Native groups in Mexico have used peyote in ceremonies for thousands of years, and other mescaline-producing cacti have long been used by South American tribes for their rituals. Peyote has been the subject of many a court battle because of its role in religious practice; currently, Arizona, Colorado, New Mexico, Nevada and Oregon allow some peyote possession, but only if linked to religious ceremonies, according to Arizona’s Peyote Way Church of God.

The “magic” ingredient in hallucinogenic mushrooms is psilocybin, a compound that breaks down into psilocin in the body. Psilocin bonds to serotonin receptors all over the brain, and can cause hallucinations as well as synesthesia, or the mixture of two senses. Under the influence, for example, a person might feel that they can smell colors.

In keeping with the human tradition of eating anything that might alter your mind, people have been ingesting psilocybin-continuing mushrooms for thousands of years. Synthetic psilocybin is now under study as a potential treatment for anxiety, depression and addiction.

Best known by its street name, “angel dust,” PCP stands for phencyclidine. The drug blocks receptors in the brain for the neurotransmitter glutamate. It’s more dangerous than other hallucinogens, with schizophrenia-like symptoms and nasty side effects.

Those side effects are why PCP has no medical uses. The drug was tested as an anesthetic in the 1950s and used briefly to knock out animals during veterinary surgeries. But by the 1960s, PCP had hit the streets and was being used as a recreation drug, famous for the feelings of euphoria and invincibility it bestowed on the user. Unfortunately, a side effect of all that euphoria is sometimes truly destructive behavior, including users trying to jump out of windows or otherwise self-mutilating. Not to mention that high enough doses can cause convulsions.

Derived from the African iboga plant, ibogaine is another hallucinogen with a long history of tribal use. More recently, the drug has shown promise in treating addiction, although mostly in Mexico and Europe where ibogaine treatment is not prohibited as it is in the U.S.

Using ibogaine as therapy is tricky, however. The drug can cause heart rhythm problems, and vomiting is a common side effect. The Massachusetts-based Multidisciplinary Association for Psychedelic Research (MAPS) reports that an estimated 1 in 300 ibogaine users die due to the drug. The group is studying the long-term effects of ibogaine on patients in drug treatment programs in New Zealand and Mexico.

Salvia divinorum, also known as seer’s or diviner’s sage, grows in the cloud forest of Oaxaca, Mexico. The native Mazatec people have long used tea made out of the leaves in spiritual ceremonies, but the plant can also be smoked or chewed for its hallucinogenic effects.

Salvia is not currently a controlled substance, according to the National Institute on Drug Abuse, but it is under consideration to be made illegal and placed in the same drug class as marijuana.

Ecstasy, “E” or “X” are the street names for MDMA, or (get ready for a long one) 3,4-methylenedioxymethamphetamine. The drug acts on serotonin in the brain, causing feelings of euphoria, energy and distortions of perception. It can also nudge body temperatures up, raising the risk of heat stroke. Animal studies suggest that MDMA causes long-term and potentially dangerous changes in the brain, according to the National Institute on Drug Abuse.

MDMA was first synthesized by a chemist looking for substances to stop bleeding in 1912. No one paid the compound much mind for the next half-decade, but by the 1970s, MDMA had hit the streets. It was popular at raves and nightclubs and among those who liked their music psychedelic. Today, ecstasy is still a common street drug, but researchers are investigating whether MDMA could be used to treat post-traumatic stress disorder and cancer-related anxiety.

The decades-long global war on drugs has failed and it’s time to shift the focus from mass incarceration to public health and human rights, according to a new report endorsed by five Nobel Prize-winning economists.

The report, titled “Ending the Drug Wars” and put together by the London School of Economics’ IDEAS center, looks at the high costs and unintended consequences of drug prohibitions on public health and safety, national security and law enforcement.

“The pursuit of a militarized and enforcement-led global ‘war on drugs’ strategy has produced enormous negative outcomes and collateral damage,” says the 82-page report. “These include mass incarceration in the US, highly repressive policies in Asia, vast corruption and political destabilization in Afghanistan and West Africa, immense violence in Latin America, an HIV epidemic in Russia, an acute global shortage of pain medication and the propagation of systematic human rights abuses around the world.”

The report urges the world’s governments to reframe their drug policies around treatment and harm reduction rather than prosecution and prison.

It is also aimed at the United Nations General Assembly, which is preparing to convene a special session on drug policy in 2016. The hope is to push the U.N. to encourage countries to develop their own policies, because the report declares the current one-size-fits-all approach has not proved to be effective.

“The UN must recognize its role is to assist states as they pursue best-practice policies based on scientific evidence, not undermine or counteract them,” said Danny Quah, a professor of economics at LSE and a contributor to the report. “If this alignment occurs, a new and effective international regime can emerge that effectively tackles the global drug problem.”

In addition to contributions from Quah and a dozen other foreign and drug policy experts, the report has been endorsed by five past winners of the Nobel Prize in Economics: Kenneth Arrow (1972), Sir Christopher Pissarides (2010), Thomas Schelling (2005), Vernon Smith (2002) and Oliver Williamson (2009). Also signing on to the report’s foreword are a number of current and former international leaders, including George Shultz, secretary of state under President Ronald Reagan; Nick Clegg, British deputy prime minister; and Javier Solana, the former EU high representative for common foreign and security policy.

Guatemalan President Otto Perez Molina, who has announced that his government may present a plan to legalize production of marijuana and opium poppies by the end of 2014, has also publicly backed the report. Molina plans to discuss the report at the U.N.

A recent Pew survey suggests that Americans may be ready to refocus the U.S. end of the drug war, with 67 percent favoring policies that would provide drug treatment.

“The drug war’s failure has been recognized by public health professionals, security experts, human rights authorities and now some of the world’s most respected economists,” said John Collins, the International Drug Policy Project coordinator at LSE IDEAS. “Leaders need to recognize that toeing the line on current drug control strategies comes with extraordinary human and financial costs to their citizens and economies.”
