I would even say that opium was likely the “forbidden fruit”.

So, why don't I? Could it be, that despite the protests of neo-prohibitionists such as yourself, I don't actually desire such a thing? I'm also not getting high on pot, acid, or heroin. You know all of those drugs are illegal right? Yet, given am hour or so, I'd be willing to bet I could locate all of them if I really wanted to. The thing that stops me is not the law or your police state. It is simply my lack of desire. I don't even take aspirin unless I really need it. All of the bad things that come from drugs are happening, yet they are all illegal, so we also get a ton of other bad things thanks to people like you who support the ever expanding police/nanny state.
The drug war is impossible to win. It is impossible to stop people who want to do drugs from doing them. I can prove that without any difficulty whatsoever.
Think of the most insanely strict totalitarian paradise you support. The police can enter everybody's dwelling at any time for any reason or no reason at all. You have no personal property, nor any privacy. Your conversations can be recorded at any time. You have no freedom of movement, no ability to do anything unless your masters tell you you have their permission to do so. There is such a place you know, and it exists right here in this country. They are called prisons. Yet drugs get in there too!. Prisons have everything you totalitarians could ever dream of, yet they still aren't drug free.
But you and your ilk have the nerve to tell me that all I have to do is give up just a little more of my liberty to usher in your impossible drug-free world. Logic is not a strong point is it? How much of your income is derived from the anti-drug police state?
