New Study Says Adolescent Cognitive Development is Impacted by Cannabis and Alcohol Use

A study published Wednesday in the American Journal of Psychiatry is shedding new light on the changing relationships between teens ’ substance use and their cognitive development. And it might even overturn some assumptions about the risks. Legalization advocates often present cannabis . It s a claim that research on adults affirms. But the fact is significantly less clear when it comes effect on developing brains. Researchers in Quebec are suggesting the reverse, that cannabis is deleterious on young minds than alcohol.

Cannabis Impacted Teens’ Cognitive Ability Over Alcohol, Researchers Say

Headed up by lead author Patricia J. Conrad, researchers with the University of Montreal tracked 3,826 Montreal teens’ alcohol and cannabis use over four years, beginning in the seventh grade, at age 13. The analysis ’s sample size represents students across 31 different schools and 5 percent of all students entering high school in the 2012-2013 academic year in the Greater Montreal area.

Researchers promised student participants that parents and teachers would not have access to their own information on cannabis and alcohol use. And over the four year period, participants performed tasks that measured their development. The study collected data on recall and working memory, perceptual reasoning and inhibition using automatic evaluations.

The study, titled “A Population-Based Evaluation of the Relationship Between Substance Use and Adolescent Cognitive Development,” then ran the data through models to determine participants’ exposure to cognitive effects, the duration of short-term and long-term consequences, and how age influenced their development.

As they expected, researchers detected commonalities between vulnerability effects for both cannabis and alcohol across all domains, from memory to justification. However, it was cannabis use, not alcohol consumption, which generated delayed effected on reasoning and inhibitory working control and recall memory, researchers say. Furthermore, they discovered the effects of cannabis on cognition to be independent of the effects of alcohol.

Because of this, researchers concluded that effects of cannabis use can be observed on significant cognitive functions and appear to be more pronounced than those observed for alcohol. ” Or in other words, alcohol was not worse on brains than weed, at least s population.

Research Continues To Show The Way Cannabis Can Harm Developing Brains

Speaking with NBC News, the analysis ’s lead researcher and chief author Patricia J. Conrad said “cannabis causes cognitive impairment and delayed cognitive development in teens. ” Conrad is a professor of psychiatry at the University of Montreal.  She’s co-authored multiple studies investigating the cognitive and psychological effects of adolescent cannabis use. Speaking about her report, the study concentrated on the neuropsychological effects of alcohol and cannabis is said by Conrad. The health risks posed by alcohol and cannabis, however, weren’t part of the analysis.

Alcohol consumption could pose a threat to teens’ health than cannabis use. But Conrad and her staff say that when it comes to brains that are young ’ ability to think, cannabis is more harmful than alcohol. It s a conclusion corroborated by scientists at the University of Pennsylvania. Conrad says studies like these are important, because they show how young peoples’ cannabis use is directly connected to their cognitive function and abilities later in life.
