  • Patent number: 4246913
    Abstract: A device for use by a smoker in developing a subconscious aversion to smoking. The device includes a special pressure transducer that is coupled to a holder for a smoking article such as a cigarette, for sensing whenever smoke is drawn from the cigarette and for producing a corresponding electrical control signal. The device further includes a transformer for converting the control signal to an electrical shock signal having a substantially higher voltage level, a potentiometer for permitting a manual adjustment of the voltage of the shock signal to a prescribed level, and a pair of electrodes for coupling the shock signal to the skin of the smoker, whereby every time smoke is drawn from the cigarette, a small, but annoying, electrical shock is received by the smoker.
