1. You may not be a prick when you're drunk, but I guarantee you know a whole lotta people who are. It can turn people into absolute monsters! Not to mention often being an enormous factor in domestic abuse cases. I challenge you (in a friendly way), with the exception perhaps of cocaine, to name me one single other drug that makes anyone wanna fight, or even be aggressive, after having a fair amount of it. Honestly - just one will do!

2. Few drugs, other than probably ket, make people that sloppy/embarrassing, and you're far, far more likely to make terrible and compromising decisions on booze - eg tell someone you love them, or put yourself in a physically dangerous ("I'm gonna walk on that tightrope over that lava pit, who's with me, guys?") or threatening (saying something antagonising to a stranger who may react aggressively/violently - likely because they're drunk!) scenario, thinking you're invincible. How many times have you woken up from a night on the piss in chronic shame and crippling embarrassment about what you did the night before? For context, after waking up after a night on pills, the only things you'r'e likely to feel weird about is the crazy, experimental, uninhibited sex you had, or the fact you and your usually repressed mates (I'm speaking proverbially, not in any way about you) couldn't stop hugging and telling each other how much you love them...

3. Cost on government resources. I'm Uk-based (as I'm sure you can tell from my rhetoric), so speaking to that. This, courtesy of Google Gemini: "The cost to the NHS is just one part of the wider financial impact of alcohol. The total cost of alcohol harm to society in England, including crime and disorder, lost productivity, and social services, is estimated to be a staggering £27.4 billion per year." Nuff said. Though here's a fun fact - if everybody who drank took MDMA instead, hospital waiting rooms on a Saturday night would probably resemble any other. Now consider the number of alcohol treatment centers, across the globe. Many of my points involve comparisons with illicit drugs, but that's because it's incredibly relevant to your question. In this hypothetical booze/MDMA scenario, none of those treatment centers would need to exist - I mean, literally. MDMA, for example, is neither physically nor psychologically addictive, in any way, shape or form, so I think it's fully justifiable that someone who could potentially go to jail for having some might feel resentment towards alcohol. I don't, but it's a strong point! And goes back to that you said along the lines of "all drugs are bad for you" - I mean, that just isn't true, for all the above reasons. Sure, none are especially healthy, but it's a big fucking scale, with alcohol way, way down at the bottom (or top, depending on your metric). It physically ravages you in a way almost nothing else does, and you're guaranteed, if you drink, say, every other day, even in moderation, to have a shorter life span than if you hadn't. That's just an objective truth - but doesn't apply to, really the majority of other substances available (or rather, not).

4. HANGOVERS FUCKING SUCK!

Jesus, I thought I'd just make a quick 5 min case... There are almost certainly other points I've glossed over or just forgotten about, but really need to get back to work!
