The tobacco in one cigar can contain as much as tobacco in ________ cigarette
ser-zykov [4K]

The tobacco in one cigar can contain as much as tobacco in full a packet of cigarettes.

<h3>How much tobacco is in a cigar compared to a cigarette?</h3>

Cigars are bigger than cigarettes so one cigar can contain as much tobacco as an entire pack of cigarettes. Cigars contain about 100 to 200 mg of nicotine while on the other hand, cigarettes contain approximately 10 mg of nicotine which means that 10 to 20 cigarettes have same the amount of tobacco as one cigar.

So we can conclude that the tobacco in one cigar can contain as much as tobacco in a full packet of cigarettes.

  • <u><em>Distal </em></u><em>has to do with anything that moves away from the center of the body, with the thoracic and abdominal cavities being proximal</em>
