Parents should be on the lookout for "weed candy."
A report on WPVI Channel 6's website says that hard candy that looks like a Jolly Rancher but is made with THC, the active ingredient in marijuana, was found recently in Upper Merion Township, near Philadelphia.
Upper Merion Police Detective Andrew Rathfon told 6ABC that a parent brought them the candy and asked to have it tested.
Parents should look for "unwrapped or re-wrapped candies that look like Jolly Ranchers," the report said.
Rathfon also said the candy could be laced with other drugs or hazardous material.
It's often made in someone's home, so people who ingest it are "trusting whoever made that substance. It's scary," he said.
"It's something parents should know about," said Limerick Township Police Chief William Albany, who posted a warning about the new drug form on the department's Facebook page.
