>GABA, which is part of the brain’s natural calming system, is strongly affected by alcohol. Scientists think this is the mechanism by which drinking can reduce stress and anxiety. GABA Labs, a firm based near London, is trying to develop a flavourless substance called Alcarelle that has a similar effect. Trials to show that it is safe could take years. But if they are successful, the firm will be able to market Alcarelle to drinks makers as a way to create soft drinks that mimic the buzzy feeling of booze, with none of the downside.

We already have GBL. It's semi-legal and feels like a long lasting ethanol. I tried it a couple times and thought it was boring. But yeah, we have plenty of alcohol alternatives already. Etizolam seltzers could be a thing.
