Marijuana joints produce 3.5 times as much secondhand smoke as a Marlboro

Now, Wayne Ott and colleagues have done a real-world study of the levels of pollution caused by smoking a joint (or a bong or vaping cannabis) and found that marijuanaContinue reading “Marijuana joints produce 3.5 times as much secondhand smoke as a Marlboro”
