gitterdun:I just wonder if it is in the blood, whether or not it can have an effect on the release of gases, if restricting the movement of blood in the system.
I don't know about the effects of nicotine per se, but the impaired lung performance caused by smoking adversely affects the efficiency of off-gassing.gitterdun:Is there an effect on off-gassing with nicotine in your system?
H2Andy:nicotine does narrow the arteries, but this is a short-term effect ... i would imagine after a 30 minute dive or so, that effect would be gone ... of course, nicotine also increases heart rate and flow of blood from the heart, so ... probably balances out anyway
smoking does put a lot of carbon monoxide in your system, which limits the amount of O2 the blood can carry ... i think that would be a much bigger problem than the nicotine itself
