Frequently Asked Questions

Q.When was the first US state to legalize cannabis?
California passed Proposition 215 in 1996, making it the first US state to legalize medical cannabis. Colorado and Washington were the first states to legalize adult-use (recreational) cannabis, both via voter initiative in November 2012, with retail sales launching January 1, 2014 in Colorado.
Q.How many states have legalized adult-use cannabis?
24 states plus Washington DC have legalized adult-use cannabis as of 2026. The most recent states to open retail markets are Minnesota and Delaware in 2025, following Ohio (August 2024) and Maryland (July 2023).
Q.What states legalized cannabis in 2025?
Minnesota and Delaware both opened licensed adult-use retail in 2025 after passing legalization legislation in prior years. No new states passed adult-use legalization in 2025; Florida's Amendment 3 ballot measure narrowly failed in November 2024.
Q.Is cannabis legal in all 50 states?
No — three states remain full prohibition: Idaho, Kansas, and Nebraska (Nebraska passed medical legalization in late 2024 but has not yet opened a program). Twelve additional states have CBD-only or limited-THC programs (TX, GA, IN, IA, NC, SC, TN, WI, MS, etc.).
Q.When will cannabis be legal federally?
No date is set. The DEA began formal rulemaking in 2024 to reschedule cannabis from Schedule I to Schedule III, which would eliminate Section 280E tax penalties for cannabis businesses. Full federal descheduling or STATES Act-style legalization would require Congressional action.
Q.What was the SAFE Banking Act?
The SAFE Banking Act (later renamed SAFER) is proposed federal legislation that would protect banks from federal penalties for serving state-legal cannabis businesses. It has passed the US House seven times since 2019 but has never cleared the Senate as of 2026.
