(Image: George Vlahos) By Leia Vlahos Alex Smith* is in his early 20s, enjoying his Friday night off with a few pints in a dingy bar just off Hindley Street in Adelaide’s CBD. Fairy lights illuminate his face as he places a small pouch between his gum and upper lip. He smiles through this discreet action: any onlookers could’ve missed it with a blink.
