Can you give a little more info? Which law? Statewide, county, or city? You might check the NORML website as they are usually really clear and up to date about the different laws.
The state laws that were passed last October affect anyone in the state who grows and/or purchases cannabis. I'm sorry, but NORML does not keep their site up to date, I always advise people to look specifically in their area and not to rely on NORML.
