As of 2022, the answer is no. Utah’s Medical Cannabis Act places tight restrictions on who, where, and under what conditions an entity can grow or cultivate marijuana. The Act further requires licensing and registration before establishing a cultivation facility, and strict compliance with processes and procedures in the operation of the cannabis production establishment.
Even a single marijuana plant can lead to felony criminal charges under the Utah Controlled Substance Act. In a home-based grow, there is also a risk that charges of child endangerment could also be filed if children are present near the growing plants. Charges can be filed even without actual contact or ingestion of the marijuana by a child.
A person who is using (or plans to use) medical marijuana should be very careful in obtaining the appropriate medical card, purchasing medical cannabis only from licensed facilities, and possessing medical cannabis only the in the forms and amounts allowed under Utah law.
