Drugs are admittedly fantastic, but potential usage must always be subjected to a simple risk vs reward equation in the mind of the user in order to avoid situations of retardation eg. overdose, accidental death etc.
No doubt the high of heroin is amazing, but heroin usage statistically involves an unattractively high probability of death in a variety of retarded possible scenarios - some of which the user is not realistically able to exercise control over.
Conclusion: reward not worth risk.
