Maybe what I read previously about Xanax wasn’t explained very well. I looked it up again today. Xanax doesn’t actually contain an extra ingredient, but does have a unique chemical structure that other benzos don’t. It’s called a triazole ring, attached to the benzo nucleus., whatever that means. This affects the way it attaches in the brain, giving it an extra “punch”, albeit short-acting, that I guess could be felt as euphoria by some. Anyway, I do know it works better for me than the others. Hope this helps.
