Abstract

An aspiration device for delivering a controlled dosage of a drug to a smoker's mouth and lungs comprises an elongated container adapted to be positioned within a cigarette or other smoking article adjacent the end intended to be held in the smoker's mouth. The container holds a supply of a drug which is aspirated directly into the smoker's mouth as a result of the suction applied by the smoker to the end of the cigarette. An air inlet port communicates with the outer surface of the cigarette and permits air to enter the container in response to the partial vacuum created by the applied suction. The drug held within the container is discharged through an exit orifice thereof which is coplanar with the end of the cigarette, so that mixing of the drug with the tobacco smoke occurs within the mouth of the smoker, at reduced temperature and lower smoke concentration. By appropriate selection of the size of the exit orifice from the container, the rate at which the drug is delivered can be controlled, so that an amount of drug proportional to the amount of smoke withdrawn from the cigarette or other smoking article can be delivered into the smoker's mouth.
