Secondhand Marijuana Exposure is Increasing

As more states legalize marijuana for recreational or medical use, there can be significant implications for current and future smokefree protections.

smoke is still smoke

Marijuana, just like other forms of smoking or vaping, is not “safe” compared to breathing clean air.

Secondhand marijuana smoke contains hazardous fine particulates and hundreds of chemicals, similar to secondhand tobacco smoke. For workers and the public, it can become another source of indoor air pollution.  Nobody should have to breathe drifting secondhand smoke of any kind in the job, in an apartment building, or in other shared air spaces.

Supporting decriminalization of marijuana  does not mean that non-users should have to breathe the secondhand emissions.

As of January, 2021, 774 localities and 29 states/territories/commonwealths restrict marijuana use in some or all smokefree spaces. Of these, 417 localities and 17 states/territories/commonwealths prohibit smoking and vaping of recreational and medical marijuana in one or more of the following venues: non-hospitality workplaces, restaurants, bars, and/or gambling facilities.
