Montana Medical Cannabis Program at a Glance
Montana's medical cannabis program, established by Initiative 148 (2004) and rebuilt through Initiative 182 (2016), remains one of the most beneficial medical programs in any dual-system state. With nearly 15,000 active patients, Montana's medical program is robust — largely because the tax savings, higher limits, and no potency caps make the $20 card a clear value.

Submit your application through the TransAction Portal:
Step 3: Pay the $20 Fee
The annual registration fee is $20. Cards are valid for 12 months.
Step 4: Start Using Your Card
