In the early 70's , it seemed every bar in Fukuoka had the whiskey with the snake in it. The bottle always had a ton of skin and scale flakes floating around in it and appeared so gross that I never tried it. For military drinkers , absinthe was the dare devil drink. It was served in tiny glasses and just 3 drinks often pet the drinker in a sleep coma for 12 hours or more. After seeing my shipmates so drunk , you couldn't wake them up , I never dared to try it. The rumor was it contained cocaine but it seemed to be the "wormwood" in it that affected the drinker.
