A new investigation from the University College London (UCL) recently reported that smoking cannabis could reduce the motivation of an individual to pursue the activity and become less enthusiastic to work for money. It seems that people who inhale just a tiny amount are more inclined to prefer a low-effort project while under the influence.
Dr. Will Lawn of UCL Clinical Psychopharmacology believes that the findings do not come as a surprise as for an extended period marijuana consumption has been linked to lack of motivation.
However, this is the first time it has been indeed examined and quantified applying a proper methodology and sample size.
Nonetheless, the study additionally found that even those individuals thought to be addicted to pot smoking had no diversity in their motivation levels when associated to control group volunteers that weren’t regular smokers, when they were not following the activity.
In other words, when the scientists compared people addicted to cannabis to comparable controls when none of the groups were intoxicated they did not find a discrepancy in motivation. So, when people stop using the drug, long-term cannabis usage might not lead to residual motivation issues. However, experts believe that more research is needed to present more convincing evidence.
For the analysis, a total of 57 volunteers were assessed. It comprised two separate investigations. During the first stage, 17 adult volunteers inhaled marijuana vapor from a balloon and later tried a placebo. After every inhalation, they were required to complete tasks for money and were paid to perform the assignments. The individuals had the possibility to earn different amounts of money by choosing between low and high effort duties.
The study concluded that those on the cannabis were meaningfully less likely to accept the great effort task.
In the second analysis, two groups of 20 people were used, one with marijuana addiction and the other without. Before being invited to decide between the same assignments as the first group, they were required to refrain from the consumption of drugs or alcohol for 12 hours. The second study showed no discrepancies in motivations of the second team of participants.
However, researchers stated that more research is needed to determine the connection between cannabis and motivational problems.
