How does cannabis affect the body?
Cannabis affects the body in various ways, impacting multiple systems and functions. The effects can be both short-term and long-term, and they vary depending on factors such as the method of consumption, frequency of use, and individual physiology.
Short-term Effects
- Central Nervous System
- Euphoria and relaxation
- Impaired memory and concentration
- Altered sensory perception
- Anxiety or panic in some users
- Potential psychotic episodes (paranoia, delusions, hallucinations)3
- Cardiovascular System
- Respiratory System (when smoked)
- Other Physical Effects
- Dry mouth
- Red eyes
- Slower response times
- Impaired coordination8
Long-term Effects
- Brain Function
- Potential increased risk of addiction
- Impaired memory, concentration, and decision-making abilities
- Possible decrease in IQ with heavy, long-term use starting in adolescence3
- Mental Health
- Increased risk of depression, anxiety, and suicidal behaviors
- Higher risk of psychosis, especially in predisposed individuals5
- Respiratory Health (when smoked)
- Chronic cough
- Increased mucus buildup

Therapeutic Potential
Despite the risks, cannabis also shows potential therapeutic benefits:
- Pain relief
- Reduction in nausea and vomiting
- Possible treatment for certain forms of epilepsy
- Potential benefits for multiple sclerosis symptoms13
It’s important to note that the effects of cannabis can vary significantly between individuals. The two main active compounds, THC and CBD, have different effects on the body. THC is primarily responsible for the psychoactive effects, while CBD is non-intoxicating and may have various therapeutic applications24.As with any substance that affects the body, it’s crucial to consider both potential benefits and risks, especially when used frequently or over long periods. More research is needed to fully understand the long-term impacts of cannabis use on human health35.
