Secondhand Smoke

Secondhand smoke from marijuana has many of the same chemicals as smoke from tobacco. This includes some chemicals linked to lung cancer.1

Protect your children and family from the effects of secondhand smoke. Do not allow anyone to smoke in your home. 

It is illegal to use any form of marijuana in the car. Keeping your car smoke-free will keep you in compliance with the law and also protect your family and friends from the toxic effects of marijuana smoke.

Can I get a secondhand (or contact) high from hanging out with people who are smoking?

Exposure to marijuana smoke is unlikely to make you "high." This means it is unlikely a person will fail a workplace urine test or driving impairment blood test after breathing someone else's marijuana smoke.1
