Yup, Pagans love their ciggies. While not all Pagans/Wiccans/etc. smoke, a little time spent at any gathering or moot will prove that many of them do. For a group of people who claim to be into natural remedies and health for their bodies and the planet, an awful lot of Pagans can't resist these air-polluting, lung-soiling little sticks o' fire.
Maybe it's just being so close to the element of fire that is so appealing. Perhaps some people feel they are getting in touch with their faux Native American roots by using a plant that is sacred to so many traditions. Who knows. Just make sure you hold your next open circle outside, weather permitting, so people don't have to keep going outside for a puff.
Most Pagans are careful not to let their butts litter the ground, however, which is more than I can say for most people.
