Drugs that can be life-threatening are commonly sleeping pills, the most effective of which is potassium hydroxide. As far as sleeping pills are concerned, there is a very large variety of them, including sleeping pills of the barbiturate type, and those of the benzodiazepine type, specifically sulpiride, triazolam, midazolam, flurazepam, nitrazepam, eszopiclone, alprazolam, and zopiclone, zolpidem, and so on, which are not available in pharmacies, and which have to be prescribed by a doctor in small quantities on a daily basis. Almost all of the poisoned drugs, or drugs that cause the sudden death of a patient, are basically unavailable in pharmacies and must be purchased in hospitals with a doctor’s prescription. Life only happens once, so it’s best to cherish it.
