Actually, Class B cigarettes were once made by Nat Sherman (tabacconist to the world). They were, yes, six or seven inches long, and available by special order only, in attractively colored papers as well. The whole Class A/Class B thing didn't always exist; at one time, cigarettes were taxed by the pack only, leading one enterprising manufacturer to market footlong coffin nails, ten to a pack, which the consumer could cut to size at will.With legal marijuana looming on the horizon, their trade name might just come back:"Head Plays".
