Marijuana comes from the cannabis plant. Despite what some people may say, marijuana is not harmless.
Marijuana smoke contains over 400 chemicals; many of these are the same harmful chemicals found in tobacco smoke. Smoking is the most harmful way to consume cannabis. The combustion of cannabis produces carcinogens and other toxins.
Smoking cannabis with tobacco has a significantly negative impact on lung health and the two products should not be combined. Studies suggest that frequent and heavy cannabis smoking is associated with cough, sputum production, wheezing and a decline in lung function. It can also increase your risk for:
- Chronic cough
- Recurring lung infections
- Cancer of the head and neck
- Heart disease
- Memory loss
- Learning problems
- Mental health problems
Babies born to mothers who smoke marijuana can have health problems, including low birth weight and prematurity.
