Researchers find lab rats on marijuana can’t be bothered

The Guardian featured UBC research that found THC, the main psychoactive ingredient in cannabis, makes rats less likely to exert the cognitive effort needed for difficult tasks.

“What’s particularly interesting is though they were less likely to do these more difficult tasks they were still able to. There’s this distinction between THC’s ability to affect your cognition versus your willingness to actually use your cognitive abilities,” said lead researcher Mason Silveira, a psychology PhD candidate at UBC.
