Study finds no link between teen marijuana use, mental health issues

The participants were separated into four different subgroups according to their personal marijuana use.


After numerous years of commentary finally it was learned that the persistent utilization of cannabis from the individuals were not made linked to medical conditions like melancholy, bronchial asthma or psychotic signs and symptoms inside of the later numerous years of their personal future.

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”.

Jordan Bechtold who led the research was also expecting similar results, but was caught off guard by what the study unfolded.

Because only males were included in the study, the researchers could not draw any conclusions about women and marijuana use.

Some previous studies have suggested that teens who use marijuana are at increased risk for cancer, delusions, hallucinations and other psychotic symptoms, asthma and other respiratory problems later in life, but this study found no such links.

The researchers concluded that there was in fact no link between teen marijuana use and lifetime anxiety, allergies, headaches, depression or high blood pressure.

Their marijuana use then declined somewhat as they got older, scientists noted. “There were no differences in any of the mental or physical health outcomes that we measured regardless of the amount of frequency of marijuana used during adolescence”. They learned that chronic marijuana use by boys did not cause various health issues later in life, such as depression and psychosis. Following this, however, marijuana use dropped to a small degree.

The study came as concerns about teenage marijuana use in states where voters have legalized the drug are at an all time high.

The study observed the data of 14-yea-old male students of Pittsburg school in the late 1980s.

“We wanted to help inform the debate about legalization of marijuana, but it’s a very complicated issue and one study should not be taken in isolation”, Bechtold informs.

Marijuana is most commonly used illicit drug among young people.


The groundbreaking study tracked 408 participants as they grew up rather than studying adults looking back on the marijuana use and current health status.
