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.

This has been known for many years insofar as people go. Now we know it about four- legged rats too.

I can see a new line of baiting traps coming out and about time too. The rats around my area are smarter than my outdoor cat. Maybe if they got high, fat and lazy, my cat might be able to catch them.

So it doesn’t make you dumber. Just makes you not give a damn about jumping through hoops for the elite

It also suggest the reason why some folks are content to remain on welfare , rather than achieve.
No wonder why O'Bungler is pushing so hard for educational mediocrity called Common Core"! where achievement is discouraged.
Socialism spreads the misery
Common Core spreads mediocrity
