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

SB 320 limits medical marijuana purchases to 2.5 ounces (70.9 grams) per week for Oklahoma patients with valid licenses. It creates the Oklahoma Medical Marijuana Authority to manage licensing, establishing standard 2-year licenses ($100 fee), short-term 60-day licenses for temporary doctor recommendations, and 30-day temporary licenses for out-of-state patients ($100 fee). The bill affects licensed medical marijuana patients and caregivers by defining legal possession limits (e.g., 3 ounces on person, 6 mature plants) and requiring state residency verification. Key provisions include mandatory online license applications, privacy protections for patient records, and caregiver licensing for homebound patients.
