But in the practical sense, for relevant real-world drugs and populations, I don't think there's any evidence that enforcement has ever had one iota of effect. People switch drugs, switch suppliers, switch habits, switch methods of consumption etc. etc. Not to mention that some drugs are legal (mostly, such as alcohol and nicotine, or partly such as various medicines), so even if "drugs" are less-consumed, the legal variant might still be just as nasty which renders the enforcement pointless despite "success". And even if overall consumption were to drop, you still might find that drug harm has not - some methods of consumption are more dangerous than others.
Given the absurd level of long-term investment there's been, you'd expect some evidence of meaningful success. Where is it?
I believe you are confused about enforcement of sale vs use, and the specifics of any policy beyond the buzzword "drug war", which is typical of this debate.
In any case, I don't want to suggest that the alternative is some kind of anarchic free-for-all - so enforcement wasn't a well chosen word (sorry!). I mean prohibition specifically, not just any kind of regulation.
If anything, I think existing "legal" drugs like nicotine and especially alcohole could use more regulation, not less.
The saying perfect is the enemy of good pretty much sums up my stance here :-) - don't bother aiming for complete abolition despite the fact that that might be a "perfect" solution if achievable.
I think the natural path for anything that is suppressed is to increase after the suppression is lifted, and then slowly decline. I wouldn't be surprised if drug legalization would increase drug use right at the beginning, but it certainly didn't have such a long term effect in Portugal -- quite the opposite.

It should be noted that we decriminalized them, not legalized them. The results shouldn't be naively extrapolated to an hypothetical legalization.
You still need to enforce against the people who deal addictive drugs, and Portugal still does.
Also, if you are caught with personal use quantities in Portugal it is usually confiscated and you are obligated to some interactions with the state aimed at treatment.
Missing the point. There is a very high addiction rate of alcohol, caffeine, porn, and sugar. Addicts are going to be addicted. Society has not yet collapsed despite these legal addictions running rampant. Closing the oxy loophole would lower oxy use. The same people would move on to different substances. What positive has been accomplished? Some of them would spend decades in jail, despite causing no other harm or threat to society. Think big picture. Are you trying to have a civil society or are you trying to end addiction? The only way to end addiction is the extinction of the human race.
What does that have to do with the War on Drugs? There is no evidence that it lowers drug use; quite the contrary.
