Earlier this week, 33 people were hospitalized after smoking synthetic marijuana -- or K2 -- allegedly purchased from bodegas in Brooklyn.
While real marijuana generally produces a mellow and pleasurable high, bad K2 can turn users into zombie like creatures.
Check out some video of what went down in Brooklyn.
The man in the last clip, James Jones, has apologized for his behavior, which included terrorizing a family of tourists.
“Their first impression of New York is me running into them. I hope I’m not the reason the city gets its reputation in foreign countries," the 27-year old told the New York Post.Jones claimed he'll never smoke K2 again.
