Nobody is talking about creating a "risk-free" world/society. We are talking about maintaining an existing functional society as opposed to letting it take a poison pill.
Of course, the way things have been going socially, perhaps a poison pill is exactly what we need. If I am of any divided mind about the legalization of drugs, this is the argument that seems most compelling in favor of it.
In my thinking, it is no accident that Drugs, Homosexuality, Destruction of Marriage and government spending us into poverty are all occurring at this point in history. They are simply different aspects of the same underlying cause.
In my ever so humble opinion, the existing society is not very functional and change is inevitable. And though I'm not sure what you mean by "poison pill", I think society went off the rails long ago.
Why? When we can't be honest, when we must alter and/or omit contrary facts and experience in order to maintain our own personal wants and desires for how things ought to be, and then ignore the damage that results, we have a life, a relationship, a family, a business, a society or whatever, that cannot exist for long.

It's no wonder people in those situations often choose to self-medicate.
And, no amount of state control will keep people from doing so. Even in the former Soviet states. Or even in a prison. Attempts to do so in a society just causes worse problems.
Society will fail when you lose trust and make human nature illegal or worse, legal for some and illegal for others.
Jesus just had two commandments. In my opinion, we each should follow them and let God take care of the rest. After all, He's still the One in charge.
