WalletHub put together a study that analyzed "Drug Use by State," ranking all 50 states from highest drug use to lowest drug use.

Drug abuse has a long and storied history in the United States, and we’ve been “at war” with it for decades. Yet despite the country’s best efforts to fight it, the problem is still prevalent. There were more than 68,400 drug overdose deaths in the 12-month period ending in October 2025, according to the CDC. - Chip Lupo with WalletHub

Montana was well within the top half, coming in as the 13th highest drug use state.
