Secondhand Cannabis Smoke

Secondhand cannabis smoke is the smoke that comes from the burning of a cannabis product (such as a blunt, pipe, or vape) and the smoke that is exhaled by the person who is smoking. Research shows that secondhand cannabis smoke has many of the same toxic chemicals found in tobacco smoke. Nonsmoking people, including children and youth, who are around secondhand cannabis smoke are exposed to the smoke and breathe in the toxins and chemicals. Research has shown that THC (the ingredient that gives people the "high") appears in the blood of nonsmokers who breathe secondhand cannabis smoke. It is safest to avoid breathing secondhand cannabis smoke.
