In April, the state Supreme Court ruled unconstitutional an earlier governor's veto of two hemp bills that had passed the legislature. It was reported that SB6, which passed 58-8 and 37–2 in the House and Senate respectively, would probably become the basis for state law.^[53][54] The state Department of Agriculture commenced rulemaking for a hemp research program at the end of April as authorized by SB6.^[55]

Polls in the second half of 2017 showed up to 78% support for the initiative.^[69]

In February, the state house passed HB 197 as an alternative to the initiative. Under HB 197, the Utah Department of Agriculture and Food would grow and supply cannabis to patients.^[70] A matching bill, HB 195, is a right-to-try law for terminally ill patients.^[71] On March 7, the bills were passed "easily" by the state senate,^[72][73] and on the 15th and 16th the bills were sent to the governor to be signed into law.^[71][74] On March 21, the governor signed HB 195 but not 197.^[75]

On March 26, the Lieutenant Governor's office validated 117,000 signatures on the Utah Medical Cannabis Act initiative, enough for it to get on the November ballot.^[76]
