The irresponsible use of drugs is very often a precursor to serious crime.
The addicted are very often inclined to commit criminal acts in order to finance their addiction.
Responsible citizens (of any nation) decry the prospect of witnessing their children being drawn yet further into a culture of a drug (or alcohol) induced euphoria, the damage caused by 'MISUSE' of either or both of these is obvious wherever such 'MISUSE' is (rapidly becoming) an accepted daily spectacle.
Those who advocate the legalization of the class of drugs known to be (and proven to be) detrimental to health, usually do so out of self interest, confused perhaps by their own little forays into the unknown and mysterious land of "WOW!"! which is the only place which enables them to enjoy their sad lives.
The occasional 'Joint' (if we must be sucked into the jargon) is not quite such an issue providing the user has the intelligence enough to avoid excess, the trouble is, they usually are not.
I would have thought that THIS thread would have developed into an intelligent exchange of views directed toward 'Praise' for the efforts of the Iranian authorities which are apparently the major barrier to an increasingly serious problem in Western society.
Whatever the outcome of 'Lawful Intervention' by those who are empowered to make decisions, I doubt if 'Heroine' (and other such substances) will ever be made freely available to those who regard a 'Buzz' as the ultimate pleasure of their lives, certainly such folk will hardly be able to force their governments to legalize such potentially damaging drugs.
They can all 'Buzz Off' as far as I am concerned.
