Perhaps, musick, but I do not believe the Yaquis were the models for the cigar store Indians. I think this idea of smoking mind altering substances is a touchy area for many native peoples...

Anyway, at the bookstore yesterday I did some follow-up.
Tobacco was used in many native american ceremonies, and had medicinal properties as well. It was offered as a blessing at the time of 'planting', and given as thanks to medicine men for their services. When it was smoked in the pipe, the actual smoke itself is believed to rise up and convey the people's thoughts to the spirits. I'm not saying that well, the concept is far more compelling....
