Though one can be stoned on any variety of recreational drugs, marijuana is the most common cause of such a state. Being stoned is what every person should do once in their life just to realize that alcohol is not their only alternative for escaping the realities of one's own conciousness. Being stoned is an intentional alteration of one's normal thought patterns for the sake of recreation. If every ignorant savage that thought marijuana should be illegal got to smoke one joint, there'd be no argument.
