Montana Legislators Reject Bills to Weaken Cannabis Laws

In 2020, 57% of Montana voters approved Initiative 190, legalizing adult-use cannabis. However, in 2025, Senator Greg Hertz (R) introduced SB 255 and SB 443 to restrict cannabis access.

  • SB 255 proposed a $200 annual registration fee and a state-run consumer registry. The bill failed without a hearing.
  • SB 443 aimed to cap THC levels at 15%, banning most products. It was defeated in committee (11-1) and rejected by the Senate (27-23).

  • The moratorium on new business licenses was extended until June 2025.
  • Synthetic THC products (like Delta-8) were banned.
  • Cannabis sales surpassed $1 billion in early 2025.
  • Over $150 million in tax revenue has funded public health, veterans’ services, conservation, and local governments.
