Applicable to both neophytes to the pipe and cigar, particularly those who are also neophytes to tobacco use: nicotine can sneak up on you.....to keep the sweats from developing into spins - or worse.
I am a newbie to pipe smoking, and I know this from personal experience.
My first time experiencing any nicotine was my initial outing with my Legend corn cob pipe, and some Price Albert. Smoked it fast (causing tongue bite), and got a case of massive sweats, upset stomach, and icky ashen taste in my mouth. Felt like I was going to pass out, and don't know how I avoided vomiting!!
Had a very similar experience about a week ago smoking back to back King Edward and Dutch Masters cigars. Smoked them incredibly fast, and got quite sick (sweats, head racing, feeling that I was going to throw up).
Slow, and steady is a much better way to go!!
