Cigars and tobacco contain nicotine which can make you feel nauseous, dizzy and sweaty. These symptoms are caused by a overdose of nicotine from a strong cigar.
Nicotine is both a stimulant and relaxant. It is absorbed through the inner lining of your mouth from the cigar smoke. It then goes straight into your bloodstream.
Advice: Limit your exposure to cigar smoke until you have built up a tolerance for nicotine.
