All You Need To Know About Nicotine
Nicotine in the diet
Nicotine is a normal part of the diet and everyone tests positive for it. In all of the large-scale clinical surveys where hundreds of subjects were tested, no person has ever tested negative for nicotine [13]
Nicotine is a normal ingredient in vegetables and everyone consumes it (13]
Nicotine is an active alkaloid [14] and an active part of the diet [15] - removing it has negative consequences for some [16], and supplementing it has benefits for some [17]
Its sister compound nicotinic acid, co-located in the same plants and with several benefits in common with nicotine, has been allocated vitamin status as Vitamin B3 (although the researchers had to invent a new name for it in order to get it accepted) [18]
You feed your baby nicotine in her mashed-up vegetables, and no corrupted medic has ever dared to claim this is a bad idea since nicotine is so closely associated with the B vitamin group that a nutritional deficiency would almost certainly be created if an attempt were made to try and artificially exclude any active ingredient such as nicotine [20].
But the question is about children vaping, which would be a bad idea for them to do, unless they had a cigarette in hand and about to light up. Kids will do what kids want to do when nobody is watching. I think most people would prefer they did neither (smoke or vape). Looking at the past century before e-cigs, how many of us could have made a better choice if we had the option.
