Major legal marijuana businesses in California are urging the state to adopt tougher safety rules for ingredients and devices used in vaping. Recommendations from the industry group, Legal Cannabis for Consumer Safety, follow a national outbreak of mysterious and sometimes fatal lung illnesses apparently linked to vaping. Most cases have involved products that contain the marijuana compound THC, typically obtained from illegal sources. The group also wants more funds to close illegal shops.
