A day after the Department of Public Health lifted its ban on vaping products, the Cannabis Control Commission has amended its quarantine order of marijuana vaping products, paving the way for them to return to the market.

The Commission will once again allow cannabis retail stores in the state to sell cannabis vaping products manufactured after Dec. 12, 2019, provided licensees make sure the products are tested for possible harmful substances. That includes vitamin E acetate, which the Centers for Disease Control suspects has contributed to several lung ailments that prompted the ban and quarantine in the first place. Products manufactured before Dec. 12 remain under quarantine for the time being.

The commission said independent testing labs have not found detectable levels of vitamin E acetate from 91 testing samples collected from 19 licensees in November. They are still waiting for results from product samples collected in December. New regulations say vape products sold will be required to list their active and inactive additives.

The change is welcome news to the growing legal cannabis industry in Massachusetts.

"The legal, regulated industry's calling card is our ability to provide legal products with a focus on consumer transparency, compassion and safety," said David Torrisi, Executive Director of the Commonwealth Dispensary Association. "Today we believe the CCC actions will put Massachusetts in a stronger position than it was prior to the ban by increasing consumer safety and responding to known risks and now will allow the legal market to move on."

Torrisi acknowledges it may still be a few days before vape products are back on the shelves, since they must be manufactured and tested before being offered up for sale.
