D.C. Police and Park Police as well as Secret Service were all on site, but there were no visible arrests. A few people were plucked from the crowd and appeared to be ticketed, however.
A Park Police spokeswoman told ABC News that they had no jurisdiction over the demonstrators since they remained on Pennsylvania Avenue and did not enter the park area.
According to DC Police, two citation were issued for public consumption.
Secret Service had not yet responded to ABC News' request for comment on the protest.
Earlier in the day, the Secret Service blocked the protesters from lugging a 51-foot inflatable joint onto Pennsylvania Avenue.
The protesters deflated the joint, and later were escorted off the premises when they blew it up against Secret Service's wishes in front of the White House.
The protesters shrugged off the fact that President Obama was not actually home and able to get a contact high. The president spent his day on the golf course.
