Synthehol is a science-fictional substitute for alcohol that appears on the Star Trek:The Next Generation television series. It allows drinkers to experience all of the enjoyable, intoxicating effects of alcohol without unpleasant side-effects like hangovers.
And cirrhosis and perhaps other deadly by-products. Aside from the "what-could-possibly-go-wrong" suspicion that acommpanies any propeller-head getting busy with mind-altering chemicals, I'm all for it!
