Secondhand Smoke
Secondhand smoke from marijuana has many of the same chemicals as smoke from tobacco, including those linked to lung cancer.1 

In order to protect your children and family from the toxic effects of secondhand smoke, do not allow anyone to smoke in your home. 

It is illegal to smoke or use any other 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?

Typical exposure to marijuana smoke is unlikely to make you feel "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
