Nov. 2, 2004 – Montana Becomes 10th State to Legalize Medical Marijuana

“Sixty-two percent of voters [in Montana] approved Initiative 148 on November 2, 2004. The law took effect that same day. It removes state-level criminal penalties on the use, possession and cultivation of marijuana by patients who possess written documentation from their physicians authorizing the medical use of marijuana… The law establishes a confidential state-run patient registry that issues identification cards to qualifying patients.”
