I used to smoke when I was a waiter.  It was the only way to get a break on a double!  No more of that going into my bloodstream anymore though.
That's good to hear, smoking is very harmful and quitting sooner rather than later is always a good thing!
Indeed!  Mostly it's dried leaves from the tobacco plant and they are rolled into long cylinders.  Some people also use a pipe.  Glad to say I use neither for Tobacco!
Yes there are many ways to consumer tobacco, as with other drugs, avoiding them at all costs is something I've tried to do over the years.
Yea they do have negative health effects.  Respiration and other various physiologic processes are effected.
It is also very addictive I've heard, with many people being unable to quit their entire lives!
Well luckily electronic cigarettes came to the market in hopes of creating the feeling of tobacco smoking with all of the negative effects.
