PHILADELPHIA — They’re having a high ol’ time at the DNC thanks to Philadelphia’s decriminalization of pot and a DNC platform moving in that direction.

“Cannabis is having a very good convention,” said Chris Goldstein, from Philly NORML, the marijuana advocacy group.

“I’ve seen plenty of open marijuana smoking in sight of law enforcement. Safety is their priority. We appreciate that.”

The convention kicked off with a cannabis welcome party Monday night at a dive bar where delegates — and even one congressman — attended.

Goldstein wouldn’t identify the lawmaker.

Protesters got in on the action by carrying a 51-foot inflatable joint through the streets.

There was supposed to be a second giant inflatable joint brought by New York pot pushers , but it didn’t make it through the entire parade because of the marchers were done in by temperatures hovering in the 90s.

Philadelphia decriminalized marijuana in 2014. Those caught with weed face a $25 summonses, while public smoking carries a $100 fine.

Police said there have been no summonses issued at or around the convention center
