In todays world drugs are everywhere. Speaking as a healthcare professional I know people will always take drugs. Many heroin users every day accidentally overdose. Theres no medically recommended dose for heroin as its use is frowned upon.
There is a drug available that halts the deterioration of a patients state when he has taken an overdose. This drug is called Naloxone and is administered in hospitals for accidental morphine(essentially heroin) overdoses. I would argue that chemists should provide this drug over the counter. We cant stop people taking heroin but maybe if we make this opiate-antagonist more freely available we can stop people dying from heroin use.
One argument against this is that if users know they can reverse any accidental overdose they might be more inclined to take more heroin, or even deliberately overdose just so they could reverse it and have the full 'trip' effect.
I dont agree with the use of drugs, but I am sick of seeing people kill themselves when it can be prevented.
