marijuana addiction:possible but not physical.

is it possible to be addicted to marijuana. well physically no, one cannot become addicted to marijuana, but mentally yes. i myself have experiences withdrawls from not smoking marijuana a day or two. not crazy painful withdrawls but more of a headache. this may be different for some. medically marijuana is not considered addictive because there is no physical addiction.. its not like if you dont smoke your body thinks it needs it, it is more like your head does.
