Not to hijack, only to add to your experience....
Doctor's visit yesterday....
He had previously invited me to google arthritis and smoking (I have a mild case of rheumatoid arthr.... I did and I found a study in Switzerland (Geneva and Zurich both) that showed the while smokers are more liable to develop R.A. that after inception, that smokers experience less progression than non-smokers because nicotine is an anti-inflammatory substance. I told him this and of course he was not pleased but said, basically, 'well IF there was a good way to isolate the nicotine that would be fine, but there are other drugs to do that and the delivery system of smoking
tobacco was worse than any benefit.'
I basically said, 'funny you should say that, because because of 'this' pulling out the 510 from my case, I was able to stop my 3 pack a day habit for over 30 years and I've found an effective way to get the nicotine without the tar, carbon monoxide and other carcinogens related to tobacco combustion and eliminate the other 4000 chemicals in cigarettes. Have you ever seen or heard of them?' He hadn't nor did the intern that accompanied him this visit. I proceeded to take it apart, explain the parts and how it worked then asked if it would be ok to demonstrate making sure they understood this was vapor not smoke so no secondhand aspect to it. They leaned in as I took it apart and seemed intrigued and interested and consented to the demonstration. I drew and let out a pretty good cloud (ecopure ;-) and I said that would dissipate shortly which it did.
Basically he was happy I had ditched tobacco and pleasantly amused at my solution and the intern looked interested. lol.
