How Ancient Viruses Gave Us Marijuana As We Know It Today

Several studies have linked behavioral problems among young people to marijuana use. But what comes first—the chicken or the egg?

According to new research published in the journal Addiction, cannabis consumption doesn’t cause adolescents to act out.

“Cannabis use in adolescence does not appear to lead to greater conduct problems or association with cannabis‐using peers apart from pre‐existing conduct problems,” the study concluded.

The inverse does seem to be true, though. Conduct problems like school truancy or shoplifting can predict whether a young person uses marijuana.

To investigate the trend, researchers at the University of Pennsylvania, the University of Oregon and the Children’s Hospital of Philadelphia created a series of hypothetical models based on self-reports from 364 young people who enrolled in the Philadelphia Trajectory Study in 2004.

Does cannabis use lead to conduct problems? Do conduct problems make it more likely that a person uses marijuana? Or does associating with peers who use cannabis perhaps lead to cannabis consumption? The results were pretty clear:

“The present findings showed that… conduct problems predicted cannabis use but not vice versa, particularly during mid–late adolescence,” the researchers wrote.

“Thus… we were able to demonstrate for the first time that increases in conduct problems precede increases in cannabis use within individuals.”

“Specifically, youth whose conduct problems change at one time‐point are likely to engage in a corresponding change in cannabis use at follow‐up, regardless of the level of those problem behaviors at the prior time‐point,” the paper, published online this week, concluded.

The team also wanted to learn about how cannabis use disorders (CUD) emerged in youth. For that, they looked at the criterion for CUD as described in the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fifth Edition, and compared them to participants’ responses to the National Survey on Drug Use and Health.

Increases in conduct problems in later adolescence were associated with higher rates of CUD, they found. Associating with peers who consume marijuana also led to increased cannabis use, which in turn seems to lead to more cases of CUD. But the researchers stressed that young people with increasing conduct problems “are susceptible to more cannabis use and CUD regardless of whether or not their friends are increasingly using it.”

“As cannabis use becomes more normative, access to the drug will inevitably increase,” they wrote. “Our results suggest that this will increase risks for CUD, especially for youth with conduct problems who are at higher risk for cannabis use and affiliation with cannabis‐using peers. If youth with conduct problems use unprescribed cannabis to cope with their condition, then healthier alternative coping strategies and support should be made available.”

Mormon Church Faces Potential Lawsuit Over Medical Marijuana Opposition

Political committees concerned with marijuana law reform in four states have waged an information war over the past year, first to qualify cannabis initiatives for the ballot, and then to support or oppose those measures in the lead-up to last week’s midterm elections. In total, over  $12.9 million in cash and in-kind services was spent attempting to convince voters about these marijuana ballot measures. Now that voters have had their say, Marijuana Moment decided to calculate how much each “yes” and “no” vote cost the committees on either side of the debate. Our calculations are based on dollars raised and disclosed before the election, since final totals of actual expenditures won’t be available until December or January reports required in the states that voted on cannabis. Michigan In Michigan, where voters approved marijuana legalization , our calculations show that the two anti-legalization committees spent about $1.28 per “no” vote, as they raised $2.37 million for ...

Mississippi Lawmakers Put Competing Medical Marijuana Measure On Ballot, Frustrating Advocates

A congressional committee approved two bills focused on marijuana and military veterans on Thursday. The action is the first markup of cannabis-related legislation on Capitol Hill this year. The bills approved by the House Veterans’ Affairs Committee are geared toward expanding access to medical cannabis for the veteran population and increasing research into the plant’s therapeutic benefits for conditions such as chronic pain and post-traumatic stress disorder (PTSD). The Veterans Equal Access Act, sponsored by Rep. Earl Blumenauer (D-OR), would allow doctors at the U.S. Department of Veterans Affairs (VA) to recommend medical marijuana to their patients in states where it’s legal. It was approved in a vote of 15-11. “Today was a monumental day for our veterans. We have been working for years to reform this counterproductive policy that forces veterans outside of the VA to receive legal medical cannabis treatment for chronic pain and PTSD,” Blumenauer said after the vote. “This is...

NY Dem Chair Warns Against Passing Voter-Supported Marijuana Legalization Bill

The head of New York’s Democratic Party said on Thursday that if the state Senate votes on a marijuana legalization bill, his party’s lawmakers run the risk of alienating voters and losing reelection next year. Jay Jacobs, the state party chairman, claimed that several “far progressive” measures, including cannabis legalization, lack popularity in certain areas across the state such as Long Island and upstate New York. He cautioned lawmakers against putting the issue to a vote, arguing that voters would “throw us out of office.” “It could be the straw that breaks the camel’s back,” he told Newsday. Polling doesn’t support that conclusion, though. According to a March 2019 survey from Quinnipiac, 65 percent of New Yorkers are in favor of allowing adults to legally possess cannabis for personal use. That includes 63 percent of respondents in upstate New York and 65 percent of those living in the suburbs. Sixty-six percent of independents statewide also back ending marijuana prohibit...
