Cigar

A cigar is a nicotine delivery device in the Generation 1 continuity family.

A cigar is a tube of dried tobacco leaves. They are designed so that a human can place one end in his mouth and light the other end on fire and puff the resulting smoke.

They are apparently also referred to as stogies.

To suppress Kup's flashbacks of slagging everyone on the planet with the crystals, Kup was given a cy-gar - a pump-thing that fed him a synthetic version of the planet's crystal energy.
