Simply put, with more differences come more things to investigate. The effects of marijuana can be generalized, but as any long-time smoker will tell you, there can be quite a variation in effects between different strains.
But this also means that it should come as no surprise that there is not a consensus on whether it makes you lazy or not! Everyone is different and we all have unique body chemistries. This makes it impossible to predict whether any of us may be prone to cannabis-induced laziness or couch-lock. If you're thinking about using marijuana in some form but are worried about becoming lazy following its use, you can try experimenting with different dosages at first.
Go with smaller dosages to start and note the results. If you find yourself becoming lazy or couch-locked after a certain dose, you can cut back. Be sure to experiment with different strains, as well, to see the range of effects that are possible. Some may feel more uplifting or energetic, like sativas, while others are relaxing or prone to couch lock. We maintain that you must experiment with different strains for yourself, as everybody's body is different.
You may find the results surprising. A specific indica, for example, could be energizing while some sativas put you to sleep. And of course, if you have any medical concerns about amotivational syndrome or feelings of dependency, it's important to talk to your doctor. Ultimately, if you're worried about cannabis-induced laziness, limiting your consumption until you become more familiar with its effects on your body and mind is a good idea.
Many people find it helpful to take notes regarding energy and motivation following the use of certain strains or methods of consumption. Taking notes can help to record objective markers that can help with a more unbiased assessment of mood and motivation.
These notes can also be shared with doctors or counselors who are monitoring your treatment. On the other hand, it's an interesting notion: that smoking marijuana would make us lazy.
There is growing consensus that cannabis's effect on our motivation, if any at all, is probably dependent on our personal habits and self-efficacy. While it would indeed be lazy to sit on the couch and smoke weed all day, is it really the weed doing that, or is it our own self-discipline and inner sense of motivation?
For many people, when they think about smoking weed, they do think about being lazy. They think about red-eyed stoners eating snacks and watching TV all day. And while that is, in fact, lazy, it is not necessarily a done deal when it comes to cannabis consumption. The effects of THC are calming and relaxing. You may find yourself becoming more lethargic or less willing to do high effort tasks, but that doesn't mean smoking weed has to make you lazy.
We cannot carry out randomised controlled trials in which some people are given cannabis for ten years while another group receive placebo for ten years. That would, of course, be unethical. Therefore, we have to rely on observational studies, where we look at associations between natural cannabis consumption and motivation levels. Some previous research has failed to find a link between cannabis use and altered motivation, although in one study earlier cannabis consumption predicted later anhedonia difficulty experiencing pleasure.
In our observational study that is, one that does not have an experimental manipulation , we compared 20 people who were addicted to cannabis against a control group of 20 people who were not addicted to cannabis. The control group used other drugs, including MDMA and cocaine, a similar amount to the cannabis group. These participants completed the same motivation task as in the previous study after they had been clean of all drugs apart from tobacco and caffeine for at least 12 hours.
We found no difference between the groups in their willingness to work for money. This suggests that long-term cannabis use may not reduce motivation after 12 hours of abstinence from the drug. However, there are some important limitations with this study. Firstly, the sample sizes were small. Secondly, the study was cross-sectional, so we only investigated the participants at one point in time.
This would have allowed for a better understanding of how cannabis consumption affects future motivation. Longitudinal research is needed to draw stronger conclusions. THC has been linked to anxiety and psychosis, as well as problems with learning, memory and attention. But the new study suggests that rather than making people less able to complete tasks, cannabis simply makes them less motivated to do so. The researchers said their findings might explain why cannabis use is linked to poorer education, lower earnings and worse employment prospects.
Scientists gave 29 rats doses of THC to see whether it made them less likely to opt for tasks that required more effort. Rats were presented with a choice of levers, with some resulting in low-effort tasks that delivered small food rewards and others leading to high-effort tasks that resulted in big food rewards. Under normal circumstances, most rats choose a harder challenge to earn a bigger reward.
But after being drugged they switched to the easier option.
