Three suburban district attorneys launched a joint appeal Thursday, urging state lawmakers to act after a 10-month grand jury probe found widespread sales of unregulated — and sometimes phony — marijuana products at smoke shops around Philadelphia.

Montgomery County District Attorney Kevin Steele was joined by Bucks County DA Jennifer Schorn and Chester County DA Chris de Berrena-Sarobe to release the investigation’s findings, titled “Unregulated, Unsafe, and Illegal: The Reality of Smoke Shops in Pennsylvania.”

Investigators purchased about 144 products sold as THC items from smoke shops across the three counties and had them tested. “The results of it were astounding,” Steele said. He reported that 93.75% of the items contained “straight out marijuana” even though they were not labeled as such. At least one business owner has been arrested as a result of the probe.

The investigation also found many products in colorful packaging that could appeal to children, and noted that some smoke-shop THC products face no sales restrictions — raising concerns about youth access. Steele said tests showed not only mislabeled products that contained marijuana but also items that claimed to contain THC but had none at all.

The three district attorneys called on legislators in Harrisburg to tighten regulations on smoke shops so consumers know what they are buying and illegal drug sales can be curtailed. Steele warned smoke-shop operators that law enforcement will continue undercover purchases and lab testing: “We are going to keep buying and, if you sell it, we are going to test it. You’re on notice, plan on getting arrested.”

This is a breaking story and will be updated as new information becomes available.
