Medical marijuana purchases; limiting amounts of certain purchases. Effective date.

SB 320 limits medical marijuana purchases in Oklahoma to a maximum of 2.5 ounces (70.9 grams) per week for patients with valid licenses. It directly affects licensed medical marijuana patients by restricting their weekly purchase amount, while also establishing the Oklahoma Medical Marijuana Authority to manage licenses and applications. Key provisions include creating standard 2-year patient licenses (with reduced fees for Medicaid/Medicare/SoonerCare recipients), short-term 60-day licenses for patients with limited physician recommendations, and temporary 30-day licenses for out-of-state medical marijuana patients. The bill also clarifies possession limits for patients (e.g., 3 ounces on person, 8 ounces at home) but focuses primarily on capping weekly purchases to regulate consumption.
