Re: How many degrees does the body/skin temperature drop when smoking?

Phyllis Pugh, a former Mad Scientist 
who also actively researches on the effects of nicotine, researched this 
question - thanks Phyllis!.

Nicotine administered directly drops skin temperature up to 2.3 C degrees.  A 
reference for that is figure 4 of Jones et al available online at

You could go look for what nicotine levels are associated with smoking; blood 
nicotine levels hover about 0.5 nM in heavy smokers.
