The Toronto Police Service has cooked up a new public service announcement, warning young adults about the dangers of a popular psychoactive party drug.

The "Cookin' with Molly" campaign was released on Friday in response to two drug-related deaths at a music festival last summer. Willard Amurao and Annie Truong-Le died in August 2014 after ingesting what police say they probably thought was ecstasy.

"This is in response to the summer rave tragedy where two young adults lost their lives as a result of consuming an unknown narcotic pill they likely believed was ecstasy, which is an MDMA compound and goes by a number of street names, the most common being Molly," Det. Chris Scherk said in a statement on Friday.

In the PSA, a shady chef is seen cooking up a batch of Molly using pure MDMA, which he grinds up before adding a pinch of bath salts to give the mix a "little heat." The man then cuts his powdery concoction with methamphetamine, "the star of the show."

Scherk says Molly is not a drug that is produced by pharmaceutical companies.

"It's made in basements, garages and on the streets."
