As more states allow for adult consumption of cannabis, it’s important to look at how full legalization is affecting medical cannabis markets. Currently, there are 39 states that have legalized medical cannabis, and 19 states that have legalized adult use. Besides South Dakota, every state that has legalized adult use had already legalized medical cannabis at an earlier date.
While the path to legalization—prohibition to medical to recreational—is standard, there are some significant differences and similarities between states that have transitioned from medical to adult use that are worth examining. In particular, we analyzed medical and adult-use sales numbers and looked at average basket size and category preferences in both medical and adult-use markets.
Early on, states were slow to transition from medical to adult legalization. California, which in 1996 was the first state to approve medical use, didn’t approve adult use until 20 years later, in 2016. This transition has moved a lot faster in recent years, in states like Illinois, which passed medical in 2013 and adult use in 2020. Generally speaking, states with relatively mature recreational markets share some distinctions that differ from newer recreational markets.
But there are a lot of other factors at play that affect adult-use and medical markets.

Sales in States That Recently Opened Recreational Markets
To begin, we’ll look at Illinois and Michigan markets, as they have both made the transition from medical only to medical and adult use within the last two years. When adult-use markets open, they tend to grow at a rapid pace. Sales in Illinois, for example, grew by 226% from $39.2 million, when they first began in January 2020, to $127.8 million in July 2021. Over this same time period, Michigan’s total adult-use sales grew from only $9.8 million
