Over the years, chronic marijuana use have been rampant amongst teenagers which led to a study on Chronic Marijuana Usage and its corresponding effects on teenage boys [depression or psychotic symptoms] contrary to previous researches.
According to Yahoo! News, University of Pittsburgh Medical Center and Rugters University then tracked the progress of 408 males from adolescence into their mid-30's with varying pot use patterns.
The research psychologists then wrote:
"Overall, data from this sample provide little to no evidence to suggest that patterns of marijuana use from adolescence to young adulthood, for the Black and White young men in the present study, were negatively related to the indicators of physical or mental health studied here."
A psychology researcher at the University of Pittsburgh, Jordan Bechtold, made a research with an expectation that teen marijuana usage would be linked to hallucinations, cancer, and other respiratory ailments but then to his surprise, none of those expectations surfaced after the study, he then stated:
"What we found 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."
Medical News Today then made a follow up report regarding the study of Jordan Bechtold's chronic marijuana use and its effect to teenager.
The 480 males that was divided into four groups were:
§ Low or none users (46%)
§ Early chronic users (22%)
§ Participants who only smoked marijuana during adolescence (11%)
§ Participants who only smoked marijuana during adolescence and continue to do so (21%).
It was then founded that marijuana is not a significant factor, as the four groups were not significantly different after being assessed on their physical and mental health issues, they also concluded that there were no difference in the findings based on race or ethnicity.
