The relationship between cannabis use and its effects on mental health has been a subject of ongoing research and debate. A comprehensive review by the University of Washington has shed light on this topic, aiming to provide a balanced perspective based on a substantial amount of research.
Firstly, it is important to note that anxiety disorders are recognized as a qualifying condition for medical marijuana in only a few states, with Pennsylvania being one of them. However, this does not imply that cannabis is a one-size-fits-all solution for anxiety. In fact, the long-term effects of cannabis, particularly on adolescents, suggest otherwise. Marijuana has been found to potentially cause brain damage during adolescence, potentially exacerbating anxiety issues in the long run and leading to a dysregulated stress response. Furthermore, it may also increase difficulties with executive functions, thus complicating the management of anxiety.
Despite some short-term benefits that marijuana may offer in coping with anxiety, well-controlled studies have highlighted the risks associated with its use. There is an increased likelihood of developing substance use disorders, indicating that the cons may outweigh the pros. Moreover, cannabis consumption can lead to short-term cognitive impairments, affecting aspects such as working memory, executive function, and psychomotor function.
Conversely, some studies suggest that low-dose THC, the main psychoactive compound in marijuana, could potentially relieve stress. However, this effect is highly dose-dependent, with very low doses reducing stress related to public speaking tasks, while slightly higher doses can have the opposite effect, potentially increasing anxiety levels. This highlights the need for caution and further research to understand the nuanced effects of cannabis on anxiety.
Long-term cannabis use has also been associated with cognitive impairments in midlife. A decline in IQ and deficits in learning and processing speed have been observed, with the severity of these effects being correlated with the frequency of cannabis use. This suggests a potential causative link, further emphasizing the need for caution.
On the other hand, cannabis contains cannabidiol (CBD), which has potential therapeutic properties and may help alleviate anxiety. However, the evidence on this matter is still mixed, and more research is needed to provide conclusive answers. Now, more than ever, there is a need for reliable information to help people navigate through the complexities of cannabis use and its effects on mental health.
