Benzodiazepines: Difference between revisions

>Keys
I added general information, emphasizing how benzos alone are rarely deadly, if at all. Meanwhile once coingestants are involved, particularly GABAergics (due to GABAa activity) such as barbiturates and most commonly, alcohol, the risk for life-threatening respiratory depression can significantly increase. Furthermore, I replaced missing or (one) incorrect citation/s with reliable sources and added IEEE in-text citations, and the corresponding full references.
