LANSING, Mich. (AP) — Michigan on Friday halted the sale of marijuana vaping products until they are tested for a compound that has been identified as a culprit in e-cigarette-related lung illnesses.

The state Marijuana Regulatory Agency’s emergency rules, which prohibit vitamin E acetate, apply to existing medical marijuana businesses and those in the process of being licensed to sell for recreational use as soon as Dec. 1.

This is the second time since September that Gov. Gretchen Whitmer’s administration has taken emergency steps to limit vaping. Her ban on the sale of flavored e-cigarettes has been blocked by a state judge and is being appealed.
