In 2004, the Montana Medical Marijuana Act was approved by 62% of voters. In 2011, lawmakers attempted to repeal the law; however, the Governor did not sign the appeal. Instead, a bill was passed and new provisions were put into place that made it extremely hard for medical marijuana patients to gain access to medicinal cannabis. For example, providers could only service three patients at one time and any doctor who recommended medical marijuana more than 25 times in one year could be audited by the state medical board. In 2016, Bill I-182 passed and amended the strict medical marijuana laws in Montana, expanding the list of qualifying conditions, allowing providers to service more than three patients and establishing licensing procedures for dispensaries. In 2017, SB333 was signed into law, adding mandatory testing, seed-to-sale tracking and new tax regulations to the industry.
