SAN FRANCISCO (KRON) — No that is not a fire! It is the smoke from marijuana.

The 420 festival at Golden Gate Park’s Hippie Hill may be the biggest day for marijuana enthusiasts.

But it is also one of the biggest days for KRON’s Stanley Roberts. Remember, Golden Gate Park is a drug-free zone.

And also, no booze is allowed in the park.

Stanley even gives Facebook Live a try to catch people inhaling badly in San Francisco.
