IPrescribe: Learning about the effects of Heavy Use of Cannabis on the person
Cannabis use is on the rise globally, and with it, concerns about the implications of heavy use. This article delves into what constitutes heavy use, the links to various illnesses, and the impact of different delivery methods.
What Is Considered Heavy Use?
Heavy cannabis use is typically defined as daily or near-daily consumption.
According to a study published in the *Journal of Addiction Medicine*, using cannabis more than once a day significantly increases the risk of adverse health effects [source: NCBI].
Links to Serious Illness
Cancer
The relationship between cannabis and cancer is complex. The National Institutes of Health (NIH) reports mixed results.
For example, a comprehensive study published in *The BMJ* indicated no significant link between cannabis and lung cancer in most users. However, heavy, long-term use may still pose risks due to inhalation of carcinogenic compounds [source: PubMed].
Respiratory Illnesses
Heavy cannabis use is associated with chronic bronchitis and can exacerbate asthma.
A study in the *European Respiratory Journal* found that regular, heavy cannabis smoking can lead to significant respiratory symptoms [source: NCBI].
Links to Mild Illness
Mental Health
Heavy use has been linked to anxiety, depression, and in some cases, psychosis.
A review in *Lancet Psychiatry* noted that individuals who use high-potency cannabis daily have a five-fold increased risk of developing psychosis compared to non-users [source: PubMed].
Cognitive Impairments
Chronic heavy use can impair memory, learning, and attention. These effects may persist even after cessation of use, as reported in a meta-analysis in the *Journal of the American Medical Association* [source: NCBI].
Cure vs. Chronic Continuation of Disease
While cannabis shows promise in alleviating symptoms of certain conditions (e.g., chronic pain, multiple sclerosis), it generally doesn’t cure underlying illnesses.
For instance, THC and CBD have proven effective in reducing chemotherapy-induced nausea but do not cure cancer itself.
Continuous heavy use can lead to dependency and exacerbate the very symptoms it seeks to alleviate.
Delivery Methods
Gummies & Edibles
Edibles offer a smoke-free consumption route but have delayed onset and variable dosing, leading to potential overuse.
Patches
Transdermal patches provide controlled dosing and prolonged effect, ideal for chronic pain without the high.
Inhalation (Smoking, Vaping)
Inhalation provides immediate effects but carries risks related to respiratory health. Vaping is less harmful than smoking but still poses some risks.
It’s crucial to stay informed from reliable, non-biased sources. Reputable databases like PubMed and NCBI provide comprehensive studies and up-to-date reviews.
Always consult healthcare professionals when considering cannabis, especially for heavy use. Do NOT phone a friend for dosing advice
