What is Legalization vs. Decriminalization?
- Legalization: Psychedelics are legally allowed for certain uses, typically medical or therapeutic, and are regulated by the government
- Decriminalization: Possession and use are still technically illegal but carry reduced penalties (for example: no jail time, only a fine, or lowest law enforcement priority)
