It doesn't make sense to get involved. As little as one cigarette can make permanent changes to your brain, and not for the better. This was a surprise to many and the research results on this will probably take years to trickle down to the "Wheel-Of-Fortune" mentalities, however it's true and even more rapidly addictive for young people.
I dipped for 12 years before becoming a JW and that was the most difficult thing to quit. A dipper (I used copenhagen, swallowed about a can's worth a week) will get about 7 times the amount of nicotine in his system as a smoker.
I suppose this was one good thing I got out of the process. It gave me the motivation to quit. I could easily return, but that would be stupid.
I disagree. Nicotine fires up the neurons in your brain and forces synapsis connection. Its actually very helpful in focusing and brain function. I use the gum and smoke and it does give a nice euphoric feeling, along with making colors more intense.
