Sorry but I totally disagree...

I smoked for over 15 years, and was also a smokeless tobacco user.

I was also in the military and that was where my "smokeless tobacco " use came into play. ( read: Red Man, and Skoal and other dips and snuffs )

It was a nasty, dehydrating habit while out in the field.

I found that nicotine made me more mellow, not more alert.

And the last thing I need is running out of a substance I'm addicted to when I'm in a survival situation.
