Breathing deep, he can't say there isn't a placating effect: that had kind of been the point, of the gum. "Bit of a placeholder for other habits," he admits.

Habits he'd never had, in this incarnation. Habits he couldn't even act on. The rarity of alcohol was surpassed only by the rarity of cigarettes, and he'd never heard of anything stronger appearing.

Weed, in his opinion, barely counts. "Scent is supposed to be pretty well tied to memory, but does it say they're for anything other than nostalgia?"
