Marijuana Quick Facts

Note: takes no position on whether to use marijuana or any other recreational drugs whatsoever. We believe in informed decision making, harm reduction, and support access to accurate information. For this reason, I have taken care to find sources that are relatively free of pro- or anti-drug biases. As usual for the Quick Facts series, all sources are cited at the end of the article.
