Philadelphia drug dealers are trying to spice up their heroin marketing campaign by stamping packets with the likeness of Golden State Warriors star Stephen Curry.

Regional transit police chief Thomas Nestel tweeted a picture Tuesday of several packets of heroin featuring Curry’s face and named. His capture rad, “Thinking Steph Curry wouldn’t be happy that he is this week’s brand for heroin in Philly.”

Philadelphia is known for having the most potent heroin in the country.

Nestel said he noticed the Curry heroin-branding this week after an officer stopped a man with the packets.

Nestel said the approach is "definitely unique" for Philadelphia. He says he hasn't seen drug dealers taking the names of other athletes or celebrities to promote their wares.
