Belive it or not, yes! nicotine is the tobacco plant's natural protection from being eaten by insects. It is a super toxin that, drop for drop, is more lethal than strychnine or diamondback rattlesnake venom, and three times deadlier than arsenic.
The pharmaceutical industry are developing nicotine-based drugs to treat a whole range of medical conditions, including Parkinsons Disease, Tourette's Syndrome, colonitis and obesity!
All plants produce allelochemicals and nicotine is one example. Billions of dollars have been spent researching nicotine but how much on those allelochemicals produced by the plants we eat and consider 'healthy'? Just how toxic, 'drop for drop', are those produced by peanuts, sweetcorn, strawberries, purple sprouting broccoli...? Potatoes, tomatoes, peppers and eggplants (and deadly nightshade) belong to the same plant family as tobacco!
A typical cigarette 'delivers' less than a thousandth of a gram of nicotine. The first rule of toxicology is "it's not the toxin, it's the dose".
