Rates of vaping-related lung illnesses were much lower in states with legal marijuana markets than in states without licensed marijuana, according to a new study.
The vaping health crisis that arose in 2019 shook the cannabis industry, even causing some state programs to temporarily ban the sale of marijuana vape products.
Data published in the journal Addiction show that the five earliest states to legalize recreational marijuana – Alaska, California, Colorado, Oregon and Washington – all had less than one case of vaping-related lung illness per 100,000 residents aged 12 to 64.
