"The Cannabis Question" explores the latest scientific evidence for the plant's medical use along with its potential benefits and risks. While millions of people can freely use cannabis recreationally or for medicinal purposes under widely varying laws, others are being jailed in states where use and possession remain illegal.

The film investigates the latest scientific evidence on cannabis, as well as how criminalization has disproportionately harmed communities of color.
