Randomized Trial to Evaluate the Effectiveness of X-22 as a Smoking Cessation Aid

"The X-22 Smoking Cessation Product is a tobacco-based (botanical) medical product consisting of very low nicotine (VLN) cigarettes.~Subjects will be allowed to smoke as much as desired throughout the 6-week treatment period."

"The Active Control cigarette is identical to the X-22 cigarette except for the tobacco, which has a nicotine content similar to that of a conventional light cigarette.~Subjects will be allowed to smoke as much as desired throughout the 6-week treatment period."
