new study of vaping-related lung injuries in California reinforces the evidence implicating black-market cannabis products, even in states that have legalized the production and distribution of marijuana for recreational use.

Just 1 percent of the patients who reported vaping THC identified a state-licensed retailer as the source of the products they used.
