• Nicotine is five to ten times more potent than cocaine or morphine in producing behavioral and psychological effects associated with addiction, including feelings of pleasure, according to a report produced by the U.K.’s Royal College of Physicians in 2007.

These expensive one shot wonders seem to ring well with retail as they pop up in chain drug stores and gas stations.
