The sales of medical cannabis and recreational marijuana are prohibited in Idaho.

As stipulated in the state's Illegal Drug Stamp Tax Act, anyone who violates Idaho law by possessing a controlled substance such as marijuana is liable to pay an excise tax.

The tax rate on a growing marijuana plant is $775 per growing plant and $3.50 per gram of cannabis or each portion of one gram. The illegal drug tax on cannabis is imposed on persons who possess one or more growing marijuana plants and more than 42.5 grams of cannabis. Revenues generated from taxes imposed on illegal marijuana and other prohibited drugs in Idaho are distributed in the following ways:

  • A portion of the revenue is retained by the Idaho Tax Commission to cover the cost of collecting, administering, and enforcing the tax. This amount must exceed the amount approved by the state legislature. Any unencumbered balance in excess of the actual expended cost by the Commission is distributed to the substance abuse treatment account by the end of each fiscal year
  • Another portion of the revenue is allocated to the state refund account for current refund claims
