As perfect as it might sound to assume that my cultural background is forcing me to see alcohol in a way that I shouldn't, the truth is that I'm not biased. I'm just being realistic. From a biochemist's standpoint, alcohol really just isn't the same as any other food. It does things to your perception and analytical skills that other substances don't; that's what makes it special. By pretending that there's nothing unusual about it, you're ignoring what makes humanity attracted to it in the first place.
Can you get addicted to other things? Sure. Caffeine addiction, for instance, is seen as completely normal in this 'conservative' society, even for children and teens. And no one cares at all about sugar addiction, despite how powerful it is.
The reason we don't dramatize them, however, is because there's not much dramatic about them. Caffeine may make you hyper or jittery, but it can't form a completely different persona for you the way alcohol can. And unless you're diabetic, you aren't likely to see the detrimental effects of excessive sugar intake until years after the fact.
My point is that there are lots of psychoactive substances, and if you want to be technical, sure, in the end it's all just food. But each one of them has its own properties, and for some those properties are more powerful than for others. That's not a 'negative' outlook, it's reality.
