The FDA and Health Canada don't want the truth, they just want to regulate what we can and can't do.
Nicotine is only 1 of the 4000 chemicals in a legal cigarette. Unfortunately we live in a world where the rich minority control the poor majority. If they stand to loose money something must be done to stop it, and we are the ones to pay.
I am addicted to caffeine, so shouldn't that be made illegal because I enjoy it, and can't live without it.
Nic calms my nerves, and for a minimum amount to be used to not be addicted is the question, it may not be the amount but how often that you use it. I enjoy getting drunk, but it doesn't mean I do it everyday.
