A new research from the University of Pittsburgh Medical Center in collaboration with Rutgers University underlines that there is no link between physical or mental health complications and teen marijuana use.
Neither depression, nor asthma, lung cancer or any psychotic symptoms could be linked to the use of marijuana by teenage boys, which according to the lead researcher on the study, Ph.D. psychology research fellow Jordan Bechtold:
“was a little surprising. There were no differences in any of the mental or physical health outcomes that we measured regardless of the amount or frequency of marijuana used during adolescence”.
The study followed 408 males since adolescence into adulthood, approximately around their mid 30s. The long span of the study makes it unique. The results were published in the journal Psychology of Addictive Behaviours, at a time when marijuana use for recreational purposes moves closer to the limelight around U.S. states.
Previous studies suggested that the chronic use of cannabis could be linked to a wide array of health and mental issues. This new release studying the long-term effects of marijuana use with teenage boys could not find any significant silverlining leading to this conclusion.
The participants in the study were grouped according to levels of marijuana use. The low or non-users amounted to 46 percent of the participants. 22 percent formed the early chronic users group. Another group represented by 11 percent of the participants only smoked marijuana during their teen years. And 21 percent started late in their teen years and kept smoking marijuana into adulthood.
The only group that exhibited a specific pattern was the second one, where the early chronic use of marijuana spiked to 200 days annually on average as the males turned 22, and then lowered significantly.
Still, no health or mental problems were reported during the follow ups, nor were there any indications in the medical records.
The 408 participants were a comprehensive population sample, including 54 percent black participants, 42 percent white participants, as well as 4 percent corresponding to other ethnicities or races.
None of the variables factored in showed any difference in results. Teen marijuana use and the alleged later-life risk of developing depression, allergies, anxiety, or any psychotic symptoms could not be linked in any way.
