One other new examine is debunking the stereotype of marijuana customers as lazy and unmotivated “stoners,” with researchers discovering no distinction in apathy or reward-based conduct between individuals who use hashish on no less than a weekly foundation and non-users. What’s extra, these frequent marijuana customers really expertise extra pleasure than those that abstain.
The analysis, printed within the Worldwide Journal of Neuropsychopharmacology, checked out information on 274 adults and adolescents who reported utilizing hashish 1-7 instances per week over the course of three months.
Whereas there’s lengthy been a stigma connected to hashish customers, with legalization opponents routinely suggesting that marijuana contributes to laziness and total apathy, the researchers on the College of Cambridge and College Faculty London mentioned their findings “usually are not according to the speculation that non-acute hashish use is related to amotivation.”
“Our outcomes counsel that hashish use at a frequency of three to 4 days per week will not be related to apathy, effort-based decision-making for reward, reward wanting, or reward liking in adults or adolescents,” the examine says. “Hashish customers had decrease anhedonia than controls, albeit at a small impact dimension.”
Research individuals took 4 assessments to measure anhedonia (the shortcoming to expertise pleasure), apathy and reward-based motivation and normal reward responses. Their outcomes have been in comparison with a management group of non-users.
What the researchers discovered was that marijuana customers have been barely extra able to experiencing pleasure, whatever the frequency of use, and there was not a statistically vital distinction between the teams when it got here to apathy.
139 individuals additionally accomplished duties to evaluate willingness to expend effort for reward (‘PhEft’ activity) and subjective reward wanting and liking (‘RRPt’ activity). There was *no* distinction between hashish customers and controls on both activity. 5/11 pic.twitter.com/Fu5adL7ThE

“We have been shocked to see that there was actually little or no distinction between hashish customers and non-users when it got here to lack of motivation or lack of enjoyment, even amongst those that used hashish day-after-day,” Martine Skumlien of the College of Cambridge, said in a press launch. “That is opposite to the stereotypical portrayal we see on TV and in films.”
“A standard stereotype of hashish customers is the ‘stoner’—assume Jesse Pinkman in Breaking Dangerous, The Dude in The Large Lebowski, or, extra not too long ago, Argyle in Stranger Issues. These are people who’re usually depicted as lazy and apathetic.”
…for instance, the ‘stoner sloth’; a (ridiculous) Australian anti-cannabis PSA.
These portrayals are stigmatising and never backed by scientific proof. 10/11https://t.co/2Bi0vvPNSB

About half of the examine individuals have been additionally requested to carry out a number of behavioral duties, like pushing buttons to earn chocolate and sweets. That experiment concerned three problem ranges, after which the individuals have been requested to charge how a lot they wished the rewards.
There was no measurable distinction between the hashish customers and management group in that experiment, the study discovered.
“We’re so used to seeing ‘lazy stoners’ on our screens that we don’t cease to ask whether or not they’re an correct illustration of hashish customers,” Skumlien mentioned. “Our work implies that that is in itself a lazy stereotype, and that individuals who use hashish aren’t any extra more likely to lack motivation or be lazier than individuals who don’t.”
“Unfair assumptions may be stigmatizing and will get in the way in which of messages round hurt discount,” she mentioned. “We have to be sincere and frank about what are and usually are not the dangerous penalties of drug use.”
Barbara Sahakian of the College of Cambridge added that this and former research strongly sign that “hashish use doesn’t seem to impact motivation for leisure customers.”
“The individuals in our examine included customers who took hashish on common 4 days per week they usually have been no extra more likely to lack motivation,” she mentioned. “Nevertheless, we can not rule out the chance that larger use, as seen in some folks with cannabis-use dysfunction, has an impact.”

The researchers additionally discovered that younger individuals are no extra more likely to expertise the potential unfavourable results of hashish measured within the examine than adults are.
“There’s been plenty of concern that hashish use in adolescence would possibly result in worse outcomes than hashish use throughout maturity,” mentioned Will Garden of the Institute of Psychiatry, Psychology and Neuroscience at King’s Faculty London. “However our examine, one of many first to immediately evaluate adolescents and adults who use hashish, means that adolescents aren’t any extra susceptible than adults to the dangerous results of hashish on motivation, the expertise of enjoyment, or the mind’s response to reward.
“Actually, it appears hashish could haven’t any hyperlink—or at most solely weak associations—with these outcomes basically,” he mentioned. “Nevertheless, we’d like research that search for these associations over an extended time frame to substantiate these findings.”

The examine concludes that “the collective proof doesn’t help an amotivational syndrome in hashish customers non-acutely, regardless of persistent ‘stoner’ stereotypes,” including that “future analysis ought to use longitudinal designs and various assessments of reward processing, look at ecological validity of reward measures, and examine day by day or near-daily customers and even youthful individuals.”
In a separate stereotype-busting examine that was printed final 12 months, researchers discovered that frequent marijuana customers are literally extra more likely to be bodily energetic in comparison with their non-using counterparts.
In 2020, a examine of older People discovered that hashish customers tended to do extra formal train and have interaction in additional bodily actions than non-consumers throughout the course of a four-month trial.
Most individuals who use marijuana report that consuming earlier than or after exercising improves the expertise and aids in restoration, a 2019 examine individually concluded. And those that do use hashish to raise their exercise are inclined to get a more healthy quantity of train.
