Using Cannabis Can Worsen Memory, Concentration and Decision-Making - Another Study Reveals

Using cannabis can affect memory, concentration and decision-making, according
to researchers.
Canadian experts reviewed the scientific evidence surrounding the drug.
They warned the effects of cannabis — or marijuana — can persist well beyond the period of intoxication.
University of Montreal scientists claimed children who smoke the drug may perform worse at school because of its effects.
And adults who use the drug, considered a class B substance in Britain, could also suffer at work or impair their driving ability.
The review, published in the journal Addiction, concluded the impairments ‘may be worse in regular and heavy users’.
More prevention measures are needed in schools to prevent adolescents using the drug chronically, researchers said.
Montreal academics analyzed existing cannabis studies involving more than 43,000 people.
All of the study papers looked at how the drug affected memory, learning, attention, processing speed, language and motor function.
Researchers looked at the extent to which cannabis affects cognitive performance immediately after taking it and in the longer term.
The studies analyzed ranged from experiments involving as few as 65 volunteers, to ones including thousands.
And they involved a range of smoking habits — from daily use to abstinence.
Heavy and frequent use was found to hamper decision-making, flexible thinking and self-control.
Other studies suggested regular cannabis use hampered the ability of people being to control their behavior, and left them less able to make ‘appropriate decisions’.

ReplyDeleteThis a great example of why clinical research is so important. There has been a ton of talk out there saying that cannabis was totally safe, but although its consumption does not have dire consequences it does have side effect, especially when consumed in a daily basis. I'm glad to learn that clinical research organizations around the world invest the time, resources, and effort into making sure that what we consume - may it be food, additives, recreational drugs, and meds - are properly tested and their side and adverse effects well known, as to prevent future unnecessary suffering in the general population. Great article!
