Twenty-nine states have medical marijuana programs, but not all are currently operational and some only cover a limited range of medical conditions. Many states without medical legislation still allow for limited use of CBD -- aka Cannabidiol, the cannabis compound that has a huge variety of medical properties but is not psychoactive (i.e. it doesn’t get you high, unlike its better-known counterpart THC). CBD is widely used to help manage epilepsy and ease symptoms of conditions such as anxiety, cancer, multiple sclerosis, chronic pain, and nausea.
Yeah. Nah. Pretty straightforward.
Decriminalized basically just means no jail time. A state hasn’t fully legalized recreational marijuana, but it has made possession of small amounts (usually 1 ounce or less) punishable by, at worst, a fine. Some states still classify it as a misdemeanor, but removing the threat of incarceration is an important step, since for years this country has been throwing people in prison for carrying as little as a single joint -- with black Americans four times likelier to be arrested as white ones, despite equal rates of marijuana usage. Some decriminalized states also have medical marijuana programs.
