Marijuana news from contributing authors and staff writers on the latest in marijuana and medical marijuana
A study just released by the American Psychological Association shows no direct link between teen marijuana use, even chronic use, and health problems later in life. The study looked at more than 400 individuals as they matured and found no evidence that marijuana use caused or contributed to any mental or physical health issues over time, including cancer and psychosis.
The Daily Caller reports:
Chronic marijuana use as an adolescent has no link to mental or physical health problems later in life, according to a new study conducted over the past 20 years.
Published by the American Physiological Association, researchers from the University of Pittsburgh Medical Center and Rutgers University divided participants into four groups from their teenage years onward.
One group almost never smoked marijuana, one used it mostly in their teenage years, another started using in adulthood and the final group of subjects started using marijuana early and continued into their adult years.
The study found that “chronic marijuana users were not more likely than late increasing users, adolescence-limited users, or low/nonusers to experience several physical or mental health problems in their mid-30s.”
In fact, there were no significant differences between marijuana trajectory groups in terms of adult health outcomes, even when models were run without controlling for potential confounds. The researchers found no link between teen marijuana use and lifetime depression, anxiety, allergies, headaches or high blood pressure.“Everyone wants to prevent teen marijuana use, but we don’t need to exaggerate its harms and arrest responsible adults in order to do it,” Mason Tvert, communications director at the Marijuana Policy Project, told The Daily Caller News Foundation.
“Hopefully, this study will lead to a reevaluation of the tactics that are being used to discourage teens from trying marijuana,” he added.
