In the short term, marijuana hinders your learning ability, but doesn’t seem to cause long-term impairment.
Marijuana makes you dumb. At least according to the tired trope surrounding its use. Back in the day, stoners were considered slackers and anyone who smoked weed was on a one-way ticket to Loserville.
Today, many of those stigmas have fallen away. But some still linger in the popular consciousness, like the perception that every hit on a joint results in a lower IQ. But does smoking marijuana actually make you stupid?
Not really, according to a review published in the journal Neuropsychology. Canadian researchers Scot Purdon and Daniel Krzyzanowski aimed to better understand what long-term cognitive effects cannabis could have on users. They analyzed 23 previous studies to determine if marijuana abstinence had any impact on verbal learning and memory abilities.
