Smoking is a practice where a substance, most commonly tobacco, is burned and the smoke tasted or inhaled. This is primarily done as a form of recreational drug use, as combustion releases the active substances in drugs such as nicotine and makes them available for absorption through the lungs.
Tobacco is a nervous system stimulant that triggers complex biochemical and neurotransmitter disruptions. It elevates heart rate and blood pressure, constricts blood vessels, irritates lung tissue, and diminishes your ability to taste and smell. This is one of the main ingredients in a cigar.
Nicotine is an addictive stimulant and is one of the main factors leading to continued tobacco smoking. Although the percentage of the nicotine inhaled with tobacco smoke is quite small (most of the substance is destroyed by the heat) it is still sufficient to cause physical and/or psychological dependence.
