Re: Controversial opinions about food

I'm surprised how few places, outside of Texas and California, know what a breakfast taco is. There's nothing like a good chorizo and egg taco on a fresh tortilla with a little bit of salsa or pico de gallo. I haven't had a proper one since leaving San Antonio.

Re: Why no artificial alcohol like there are e-cigarettes?

IIRC, alcohol doesn't actually kill brain cells and moderate drinking has no cumulative long-term effects. Though maybe we're thinking of a different definition of "moderate". In my view, a moderate drinker does not drink to the point of functional impairment. A moderate drinker can safel...

Re: Why no artificial alcohol like there are e-cigarettes?

They know very well how alcohol affects the GABA system in the brain, and so drugs that target the GABA system more selectively - but without the toxicity alcohol has - are relatively easy to find. You're probably referring to bendoziadepines , which include things like Librium, Valium and Xanax. I...
