Temperance and Drugs
There's an interesting commonality between the Temperance-Era activists and those proclaiming the ideal of being "drug-free" today: neither of them are really advocating the Christian virtue of temperance at all. The great Christian apologist C.S. Lewis explained the true meaning of temperance in his book "Mere Christianity":

"[Temperance] now usually means teetotalism. But [originally], it meant nothing of the sort. Temperance referred not specially to drink, but to all pleasures; and it meant not abstaining but going the right length and no further. ... Mohammedanism, not Christianity, is the teetotal religion. ...

The nimble Christian principle of temperance demands abstinence when it's needed: abstinence from pleasure drugs is appropriate for kids and, generally speaking, for expectant mothers; abstinence from anything that impairs skill and judgment is necessary when driving, operating machinery, etc. But for mature adults, there is no logical reason whatsoever to prevent them from enjoying whatever pleasure they care to pursue, so long as they are not endangering others.

The bible says - "[Wine] has been created to make men glad. Wine drunk in season and temperately is rejoicing of heart and gladness of soul. Wine drunk to excess is bitterness of soul, with provocation and stumbling."

There's no permissive slack here. Approval and rebuke are side by side, just as when a parent trusts a child with a treasured possession saying "use it, but don't break it." This is exactly the attitude that allows the Judaeo-Christian tradition to call a Godly creation "very good" without endorsing human abuses of it.

The real danger of any pleasurable activity is when you take away the right for people to control themselves, take away the assistance for those who can’t, punish those who indulge and create a black market where huge profits can be made, so that crime, violence and even war become the natural outcome – all over something that is completely natural, completely human – the pursuit and enjoyment of pleasure. Nowadays, you can be locked away for ten years for doing nothing more than providing chemical pleasure to people – something a publican does every day, while murderers get out on parole after six months.

That kind of legal logic is completely devoid of prudence and justice, fortitude is nowhere to be seen, as politicians bow to the alcohol-consuming majority even though alcohol kills 50 times more people each year than all illegal pleasure drugs combined.

Still, many people are eager to see drug users and dealers punished. Perhaps Jesus would have confronted this mob like he confronted those who surrounded the woman taken in adultery: 'Let the one among you who has never been drunk and never patronized an alcohol dealer slam the prison door on this druggie.'

Our so-called Judeo Christian society has completely lost the meaning of the cardinal virtues. At first glance, classical Christian temperance seems permissive next to the "drug-free" ideal. But in the end, true temperance is a higher standard, more wholesome and more demanding on our society. It calls for responsible citizens, not obedient subjects. It calls for compassion for those who succumb to addiction of any sort, and it rejoices in the capacity for humans to experience pleasure.

As for those who fail to distinguish the goodness of wine from the evil of drunkenness, St Chrysostom chided them as "the simple ones among our brethren.". "Wine makes not drunkenness; but intemperance produces it. Do not accuse that which is the workmanship of God [wine], but accuse the madness of a fellow mortal. Otherwise you ... are treating [God] with contempt."
