Marijuana makes rats lazy, less willing to try cognitively demanding tasks
University of British Columbia @ medicalxpress ^ | August 24, 2016 | University of British Columbia

New research from the University of British Columbia suggests there may be some truth to the belief that marijuana use causes laziness— at least in rats.

The study, published today in the Journal of Psychiatry and Neuroscience, found that tetrahydrocannabinol (THC), the main psychoactive ingredient in marijuana, makes rats less willing to try a cognitively demanding task.

"Perhaps unsurprisingly, we found that when we gave THC to these rats, they basically became cognitively lazy," said Mason Silveira, the study's lead author and a PhD candidate in UBC's department of psychology. "What's interesting, however, is that their ability to do the difficult challenge was unaffected by THC. The rats could still do the task— they just didn't want to."

For the study, researchers looked at the effects of both THC and cannabidiol (CBD) on rats' willingness to exert cognitive effort.

They trained 29 rats to perform a behavioural experiment in which the animals had to choose whether they wanted an easy or difficult challenge to earn sugary treats.

Under normal circumstances, most rats preferred the harder challenge to earn a bigger reward. But when the rats were given THC, the animals switched to the easier option, despite earning a smaller reward.

Most rats that smoke pot live in their parents basements.

"..They needed a study to figure this out?"

No chit. I'd only charged'em half as much for the same info!

"Heads" are gonna be lackadaisical about the schedule and don't expect any revelations out of them that don't involve optical effects.

Pretty easy, really. d;^)

"Which explains why the highest useage of HC and marijuana occurs in Democratic controlled cities."

To the researchers with this break through study:

Heh, sounds better than alcohol, where you will try every brainless thing you can’t really do and get yourself and/or others injured or killed.

I’ve no less respect for those that work for their weed than those that work to make or buy their beer and spirits.

That's an assumption the researchers made. It could also be...

Marijuana makes rats lazy, less willing to try cognitively demanding tasks put up with the tyranny of being lab rats.

Sadly, after graduation, one of those friends — a bright kid otherwise — became a mid level dealer, was caught, and did hard time in state prison. The last time I saw him, at a high school reunion event, he was still on probation and kept glancing about as if he expected to be grabbed by the cops and cuffed — or maybe shanked by a fellow inmate.

"cognitively lazy"?

I've seen it too many times. Friends and relatives living diminished lives. Sometimes, very diminished, even wasted lives. Some escape, I do admit, but when you add in the chance of arrest for breaking the law, and the expense in paying to break the law, it isn't worth it, in my judgement.

Same thing for people, which is why the dems are so eager to get pot into the hands of the folks.
