The three-day music festival known as Boston Calling begins Friday in the Harvard stadium in Allston. The concert series has grown in the past decade or so to include more bands, feature guest comedians, move a larger venue and attract more and more people. This year, the festival will bring headliners 21 Pilots, Tame Impala, Travis Scott to the music stage, with comedians Fred Armisen, Jenny Slate, and SNL's Michael Che in the show tent. Dozens of other bands and performances will make appearances on stage throughout the weekend.

With the uptick in attendees and the legalization of marijuana possession in Massachusetts, police are planning to be more vigilant than ever in seeking out and fining anyone smoking weed in public, which is currently against Massachusetts law.

CBS Boston reported that the Boston PD's vigilance is spurring Massachusetts citizens to push for marijuana permits. Joe Gilmore of the Massachusetts Recreational Consumer Council told CBS Boston that in many cases, marijuana is far less damaging than alcohol.

“I think it’s so hypocritical. As you can imagine, there’s so much more deaths from alcohol every year,” Gilmore said. "If you can have an alcohol permit, why can’t you have a cannabis permit?"

For the time being, if you're heading to Boston for the best music fest the city hosts all year, be sure to follow Massachusetts' current laws regarding cannabis possession and consumption.
