I picked up smoking in college, Freshman year, 1981 and didn't quit until 1995 when I decided I wanted to see what my body could do while it could maybe still do it.

From the perspective of a customer,
Nothing much to say starting out here since I'm pretty new to the forum, other than to say that the FDA's been behaving in a most unscientific manner.
My contribution so far has been to bring the perspective of a professional chemist to the mix.
I've mostly been messing around with showing folks how they can figure out the nicotine content of their e-liquids themselves without a lot of fancy equipment.
