It has been found in a new study that use of marijuana in teen age doesn't lead to asthma, depression and lung cancer in adulthood. The study has been published by American Psychological Association. The study is opposite to what was thought earlier.

As per reports, the conclusions of the study were documented following tracking hundreds of participants from youth into their mid-30s. The study was conducted only on male participants. The research was conducted by dividing the participants into four groups.

One group was having those who hardly ever or never used marijuana and second was having those who consumed marijuana in early years of their life. Third group consisted of those who used marijuana in adolescence and fourth started consuming marijuana in their late teenage years and continued using it through middle age.

According to Jordan Bechtold, lead researcher from University of Pittsburg Medical Center, "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".

As per reports, early chronic users were using marijuana to a greater extent and consumption by them kept on increasing until they reached 22 years of age on average bases. The use of marijuana decreased as they became older. A research looking at the long-term health impacts of teen marijuana use was expected for the reason that marijuana has been legalized for other purposes in several states.

According to Bechtold, they were looking forward to give explanation regarding the debate related to legalization of marijuana, however it's a quite complicated matter and one study is not enough to come up with satisfactory conclusion.
