Alcohol Without Liquid (AWoL) is the trade-name for a vapourised vodka product that's dispensed through a portable booze-bong that has become trendy in London clubs. Now NYC meatpacking district clubs have taken up the craze and are selling booze-inhalers to their customers.
AWoL users pour a shot of their favorite spirit into a diffuser capsule, which is connected to an oxygen pipe.
Oxygen bubbles are pumped through it, absorbing the alcohol and creating a smoky-looking vapor, which is then sucked through a tube and inhaled.
