A mandatory recall this week has pushed Pennsylvania regulators to recalling hundreds of medical marijuana vape products.
The state has said that they contain ingredients that have been unapproved for inhalation.
Pennsylvania’s health department released a list of more than 500 cannabis vape products with ingredients not approved by the U.S. Food and Drug Administration.
“Although some of these added ingredients may be considered safe in other non-inhaled products, patient safety is the top priority of the Medical Marijuana Program,” the state wrote in an email announcing the recall, according to the Pittsburgh City Paper.
The mandatory recall may have impactful consequences for producers, processors and retailers who rely on the vape market for sales.
The recall comes after a monthslong process in which the state reviewed medical marijuana vape products.
It was last November that state regulators gave licensed grower/processors two weeks to resubmit vaporized cannabis products that contain additives, including flavors or terpenes, for approval.
Health officials then told patients in December that some of the products sold by medical marijuana retailers might not be safe to inhale.
