This might just reopen a great conversation.
Compared to America's legal drugs of choice, alcohol and nicotine, marijuana is relatively harmless, in terms of the health effects. Far from creating monsters, as alcohol can, it creates a mellow atmosphere, where strangers can become friends. The mild hallucinogenic effects, the way it opens up reception to stimuli, and the way it makes all such stimuli fascinating are all in contrast to the hyperactivity of nicotine, and the depressive, even narcoleptic effects of alcohol.
Plus, it does seem to mitigate certain issues in regard to appetite and pain relief under certain circumstances.
The debate over the legalization of pot has yet to finish, and Robertson's endorsement of decriminalization seems a huge step forward. While I doubt Pat fires up a hookah, it does offer a comical moment, too, the picture of moral rectitude sucking a fatty as a way of helping hear a Word from the Lord.
