It never ceases to amaze me how often I hear people say that because they have a physician’s recommendation to use medical marijuana, or a Medical Marijuana Program Act ID card, they can smoke marijuana anywhere while doing anything…even while driving! Before delving into the inaccuracies of the above statement, let me be crystal clear on one issue: possession of marijuana is illegal under Federal law and any advice rendered, applies only to California state law.
Before I explain where you can smoke medical marijuana legally in the state of California, perhaps it would be better to start by explaining where you cannot smoke medical marijuana. Under California state law, you cannot smoke medical marijuana in any place where smoking is prohibited by law; in or within 1,000 feet of the grounds of a school, recreation center, or youth center, unless the medical use occurs within a residence; on a school bus; while in a motor vehicle that is being operated; or while operating a boat. That being said you are free to smoke in any place that is not listed above.
