Infrequent Cannabis Use Results In Impaired Learning Skills In Teens, Study Says


According to the latest reports, cannabis use is not recommended even if it’s only infrequent. The Ste-Justine Hospital-Université de Montreal study discovered damage to primary cognitive functions that have been more intense than the ones triggered by alcohol use.

The hospital’s study showed that cannabis use even if it’s infrequent can affect the teens’ skills necessary to succeed in school.

The research that has been conducted by the hospital and published in the American Journal of Psychiatry showed that the effects of weed use could be observed on primary cognitive functions and it seems to be more prominent than the ones of alcohol.

Alcohol and cannabis use has been associated with changes in the teens’ learning abilities, their memory, attention span, and decision-making abilities.

There have also been weaker academic performances after the use of cannabis as well.

“These are skills that are not directly linked to academic performance,” says study co-author Jean-François G. Morin. “But they are necessary in order to perform well.

Not only regular cannabis use is dangerous 

Morin also added that these changes do not only affect those who regularly consume cannabis. “There is no zero risk when it comes to (cannabis) use. … Really, it’s important that the public — particularly young people — have this information.”

It seems that in order to understand the relationship between alcohol, cannabis and cognitive functions in teens, regardless of the level of consumption, researchers have been following 3,826 Canadian adolescents for four years.

The authors studied the relationship from one year to another between substance use and the development of several cognitive functions which include the ability to remember, perceptive reasoning and inhibition as well.

The study also demonstrated that the use of alcohol and cannabis during the teen years is usually associated with poorer performance in all of the cognitive areas.

One important thing which continued to be highlighted was that the cannabis use did not have to necessarily be frequent; the results were also the same in infrequent use of the drug.
