If marijuana is approved at the recreational level in Montana, citizens in the state should not expect rapid changes. There will need to be an extensive framework put into place that establishes regulations on the industry. Estimates by the group that introduced the ballot initiative, New Approach, say that sales of marijuana in Montana will generate $48 million and tax revenue for the state by the year 2025. This constitutional amendment would only allow the legislature to set the legal age for marijuana usage to 21 years or older, similar to the limitations on the purchase of alcohol. In all likelihood, if recreational marijuana is approved, residents in Montana would only be allowed to carry a certain amount of cannabis on them at a time, or they would still face certain types of drug charges.
