Apart from being a drug (albeit one with no noticeable ‘high’), nicotine is also a powerful poison and tiny amounts are used in many commercial insecticides. If the nicotine content of just one cigarette were injected directly into your bloodstream, it would kill you. In fact, tobacco contains hundreds of poisons, including benzene, polonium and cyanide. This should not come as a surprise as the tobacco plant is from the same family as the Deadly Nightshade. In addition, many cigarettes also contain toxic additives such as ammonia and formaldehyde.
