As a bartender in the 90's there were popular cocktails that did this. High alcohol, large round glass, set alight, put your hand over to extinguish, push a straw through fingers and suck out the vapour. The effect was very quick and very strong, much more so than drinking spirits alone. It was also short lived. I'm sure these were a terrible idea, but still, people using alcohol vapour to get a hit.
