Well, that's a whole other debate, but yes.
There is an argument for decriminalising drugs and allowing Smack R Us stores to pop up on the high street. I think there's (at least) two issues with this.
Firstly, that sort of paradigm shift would be incredibly hard to implement, and I suspect widely unpopular. I can't imagine many people not having an opinion on it.
Secondly, making it legal sort of gives it a seal of approval, it makes it normal and 'safe'. Whilst the dangers of alcohol are well reported, I'd hazard that the problem drinkers - the alcoholics and the ones who think a good night is twelve pints of Stella and a glassing - are actually a minority. Compare and contrast, say, heroin. Is there such a thing as a casual heroin user? Can you see people having a lunchtime wrap with their meal of a Tuesday lunchtime?
For me personally, I've never touched any 'hard' drugs. Part of that is probably down to successful campaigning - I grew up in the 80s, so I know that Zammo chased the dragon and got a smack on the nose, and also learned the life skill of how to put a condom onto a banana - but I think a big part of it is that my brain perhaps recklessly connects "it's legal, it must be relatively safe / it's illegal, it must be really dangerous." As such, I was drinking in my mid-to-late teens but had absolutely no desire to find out what that cocaine stuff was all about. (As an adult I've subsequently learned that coke is basically instant tedious arsehole mix, so I didn't miss much it seems.)
I can't say for sure, but if harder drugs had been normalized when I was young I perhaps would have had a different attitude to them. And certainly they'd have been easier to obtain, my exposure to drugs and users is relatively tiny; I don't think I even saw cannabis first-hand until I was at university.
