Illinois set another record for recreational cannabis sales in 2023, with more than $1.63 billion in sales. While sales to out-of-state residents showed a significant drop as additional states joined Illinois in legalizing the adult use of cannabis, sales to Illinois residents increased by 14%. Overall, Illinois saw a 7% increase in retail cannabis sales, resulting in $417.6 million in cannabis sales tax revenue.

Recreational cannabis sales have increased each year in Illinois since legalization in 2020. However, Illinois has some of the highest cannabis prices in the country, along with some of the highest taxes, driving some customers out of state. Marijuana sold in Illinois, the third largest market for legal cannabis in America, ranks as the most expensive.

Under the law, Illinois residents can have 30 grams of cannabis flower, five grams of cannabis concentrate, and no more than 500 milligrams of THC contained in a cannabis-infused product. Residents in the medical cannabis pilot program may have more than 30 grams of flower, but only if it is grown and secured in their residences under certain conditions.
