Marijuana makes rats lazy, less willing to try cognitively demanding tasks
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.

It is not cool anymore here. Only idiots smoke the stuff these days. Try and find a coffee shop.

But amongst kids it is definitely not done here. Smoking normal cigs is I am afraid but it is declining. Recreational drugs are on the rise along with old friend alcohol.

Re: Marijuana makes rats lazy
I admit, I am a lazy fucker. I find, however, that I'm actually less lazy if I hit the bong, makes me get up and do things. I will be hitting it soon, as I've got a shitload of electrical work to do on a boat and it's boring as all fuck without a bowl and some decent music.
The asshole boat broker had it on his lot and didn't check it after several big rainstorms. The deck drains got clogged up with debris and the battery compartment, which is under the back deck, flooded. All the fucking wiring to the batteries corroded to dust. He's no longer representing the sale and he's lucky I'm not suing him.
Here she is

Propellers make me uncomfortable
I prefer a jet drive
Oh, and of course marijuana makes cats lazy. Cool cats

People think "queue" is just "q" followed by 4 silent letters.
But those letters are not silent.
They're just waiting their turn.

I'd love to have jet drives but they don't make a conversion kit for those particular engines.

Re: Marijuana makes rats lazy
That's partly why I still smoke it. I'm the antithesis of cool, I am the Uber Uncool, I'm so utterly, absolutely, unrepentantly uncool that I'm actually cool.
I don't follow fashion, I set it.

Like most things depends on metabolism....some chill to drink some get aggressive...some get stoned on drugs and some get busy. All depends on how the molecules interact. Live and let live as they say.

Speaking of which, my neighbor gave me a nice bud of Bubblicious, a sativa dominant hybrid. Think I'll try a bowl. The sun is hot and the pool is chilled, there's beer in the beer fridge and a beef roast in the oven, there will be Yorkies for us this afternoon. God is in his Heaven and all is right with the world, or at least with my little corner of it.
And it will stay that way goddamnit, and I'll shoot any motherfucker who disagrees.
