The San Francisco Board of Supervisors could be trying to legislate that “…everybody must get high”.
If you actually inside city hall, its okay to smoke medical pot. Likewise if you are on the street at a fair, festival or any other outdoor event that occurs on city property. What is not okay is smoking anything else.
Eric Mar, San Francisco Supervisor sponsored this proposal which is being considered in the city.
