There is a tobbacco shop in the town where I live, called the Owl Shop. I went in there one day out of curiousity; but intending to attemp to buy some herbal, tobbacco free cigarettes out of curiousity. I saw ginseng cigarettes, $5.25 for a pack of 20. The box says, 'tobbacco free, nicotine free.' I decided to try them. Because they have no tobbacco, I did not need to show an I.D.
I returned to my fraternity house, and my roommate and myself each smoked one. He experienced something similar to a strong nicotine buzz; I experienced a sudden urge to have a grin on my face and felt rather loopy and giddy. Another person felt no buzz. I enjoyed the cigarette and found it rather smooth, but they left a dead-fish smell in the room.
I've hunted around a bit for info on ginseng cigarettes, but I have not been able to find any referances so far. The pack says, 'Imported from England.'
