Cannabis legalization was on five state ballots yesterday and ran the table.

Voters in Oregon, where cannabis is already legal, also approved a measure addressing street drugs and another that sought to legalize psychedelic mushrooms’ therapeutic use.

Of the five states that voted on cannabis, four states approved legal recreational marijuana for adults age 21 and older. Mississippi approved medical use, while South Dakota approved both recreational and medical use at one time.

This is a critical time for cannabis startups as they look to new markets. Many companies in this space look at each new state as a gold rush as they seek to win over consumers and businesses alike. But it’s going to take time. Each state has different rules and regulations that cannabis companies need to explore and navigate.

Ten years ago, cannabis was illegal across the United States. That changed in 2012 when voters in Colorado and Washington approved recreational marijuana. While it’s still illegal at a national level, with these new states, one in three Americans will soon be able to buy weed legally.

New Jersey

• New Jersey becomes the first state in the mid-Atlantic region to pass such a measure.

Montana

• Voters in Montana approved a measure and constitutional amendment to legalize weed and set the adult-use age to 21.
