Mixing cannabis

Mixing Cannabis

Mixing cannabis and tobacco should be avoided. This increases your risk of harmful respiratory symptoms. Dual use is associated with higher adverse health effects due to higher toxic exposure. Mixing cannabis with tobacco also exposes you to nicotine, making it more addictive.

Cannabis smoke contains more than 450 chemicals and cigarette smoke contains more than 4,000, many cancer-causing. When mixing cannabis with tobacco, you also increase the risks associated with second-hand smoke that contains many poisons including ammonia and cyanide. Third-hand smoke, the leftover residue left on clothes, furniture and carpets can also worsen respiratory symptoms.
