International Business Times reports on a test done on laboratory rats to determine if THC in Marijuana makes you lazy.
Does cannabis make you lazy? A study was done on lab rats.
A study published in the Journal of Psychiatry and Neuroscience done by University of British Columbia reports that researchers found male rats were less keen to try cognitively demanding activities after they were given THC (Tetrahydrocannabinol), the main psychoactive compound in cannabis.
In the study 29 male lab rats were tested with THC and CBD (cannabidiol) to determine their eagerness to make an effort at cognitive tasks under the influence of these two compounds respectively.
Rats were given a choice between 2 options differing in reward magnitude, and cognitive effort required to obtain them. The experiment required the rats to respond to a light by touching it with their noses in order to receive either one or two sugar pellets. The easier task would get them one sugar pellet and the more difficult task would earn them two.
Without either THC or CBD the rats willingly chose the more difficult task for the bigger reward. After a dose of THC they all chose the less strenuous task for less reward. However after they were dosed with CBD (the non-psychoactive compound in cannabis) there was no effect on the decision-making or attention span of the animals. Researchers also discovered that CBD had no effect on the THC-induced laziness.

Researchers are not surprised
Mason Silveira, lead author of the study, and PhD candidate in UBC’s department of psychology, said they were not surprised to find that when they gave THC to the rats, they basically became lazy. But what the researchers found fascinating, is that their ability to do the difficult tasks was unaffected. They could still do the task they just didn’t feel like doing it.
Senior author of the study Catharine Winstanley and associate professor said the biggest surprise aspect of the study was to discover that CBD, which researchers say can be used to treat pain, cancer and epilepsy, didn’t block the effect of the THC. The belief was that CBD in high concentrations diminishes the negative effects of THC, but unfortunately it looks like it is not the case in this instance.
She concluded by saying these results should lead to further research on the effects of CBD and THC on the human brain as researchers dig deeper to push for medical marijuana as relief for pain without the cognitive effects.
The conclusion of the study: These findings confirm that THC, but not CBD, selectively impairs decision-making involving cognitive effort. However, co-administration of CBD only partially improves such THC-induced dysfunction.
Should we invest or are we becoming lazy?
In the meantime the article in International Business Times also includes information on the US projected growth in recreational and medical cannabis sales, 2016 shows $7,100,000,000, and 2020 will see an increase to $22,800,000,000. Is IB Times suggesting the USA will become a lazy nation at this rate, or are they suggesting everyone should invest in an emerging market? We’re not sure at all.
Does cannabis make you lazy?
THC might affect lab rats to the extent that they become less keen to do hard work, or it could mean they’re suddenly not so keen on sugar. This study leaves many unanswered questions. Maybe the rats on THC became conscious of being used in an experiment? Does cannabis make you lazy? Isn’t rest the best way to heal a sick body?
