Here is an overview of the medical marijuana laws in Utah:
2015 – Senate Bill 259 was a proposed by Senator Mark B. Madsen (Republican, Saratoga Springs) with eight working days left in the legislative session. The bill was defeated in the Senate on a 15–14 vote, with several senators citing the relative rush behind the bill as the reason for their no vote.
2016 – Senator Madsen again attempted to pass legislation legalizing the use of medical cannabis through Senate Bill 73. The bill eventually passed the Senate 17-12.
2018 – In February 2018, the Utah House of Representatives passed HB 195, a bill to legalize the “right to try” and grow medical marijuana plants for terminally ill patients.
On November 6, 2018, The Utah Medical Cannabis Act was passed as ballot Proposition 2. Provisions must be set by the state for dispensaries to open by January 2021.
On December 3, 2018, the Utah Legislature passed HB3001, amending the Utah Medical Cannabis Act as passed through Proposition 2. The Governor signed HB3001 into law later the same day, causing it to go into immediate effect.
