Weed. Anything made out of tobacco has nicotine.
Yes; along with numerous other toxins emitted from the burning of the cigarette/cigar.
You shouldn't inhale cigars because they are high in alkaline and high in nicotine, and inhaling will make you cough. You can enjoy the flavor of a cigar without inhaling because the nicotine is absorbed by the mucous membranes of the nose and mouth. (Cigarette smoke being acid, it is almost exclusively absorbed in the lungs.)
There really isn't an equivalency because of the way they're smoked. When you smoke cigarettes you inhale, so you get all the good carbon monoxide and other fun chemicals in your lungs, and into your blood. Plus, cigarette smoke is acidic and it seems that pH affects the addictive quality of nicotine.
A "butt", in terms of smoking, is the unburnt portion of a cigarette or cigar that is thrown away by the smoker. They contain concentrated coal tars and nicotine, and some people who are desperate for a nicotine fix pick them up and smoke them.
Drink water while you smoke. A little sugar on the tongue will curve the nicotine buzz.
The only danger in smoking one cigar would be if you are tempted to smoke another one, which eventually can lead to nicotine addiction. It is better not to take the chance. Just say no to tobacco. - - - - - The addictiveness of nicotine is directly related to the pH of the smoke. Cigarettes, which are addictive, have acidic smoke. Cigars have alkaline smoke, and they don't seem to be as addictive as cigarettes. Some cigar smokers never get addicted although they've smoked for years--they can stop smoking cigars for a few weeks and not suffer withdrawal. As to the question: no, one cigar in a lifetime won't hurt you.
No a dog can't smoke a cigar.
Zero! You might get a smidgon if you chewed on it for hours.
