Seventy percent of Americans now support legalizing cannabis for adults’ use. Twenty-four states have legalized and regulated cannabis for individuals over 21, though some of the newer laws are still being implemented. Washington, D.C. voters also legalized cannabis for adults, but because D.C. cannot control its own budget, Congress has been able to block the District from taxing and regulating cannabis sales.

A conviction for possession of a small amount of cannabis can lead to a lifetime of harsh consequences (also called collateral sanctions).
