Always amazes me that LSD is illegal while alcohol is legal, the latter causing all host of metal and physical ailments, the former causing mostly hilarious navel-gazing
It always amazes me how many people on HN trivialise extremely dangerous drugs saying that alcohol is more dangerous. I'd rather stay in a room with someone that drinks a glass of wine a day than with someone that assumes LSD every day.
In addition, the comparison would work better with pot. Would you rather spend time with someone drinking a bit or that smokes a bowl every night? That gets to be a much more fuzzy.
In addition, there are questions like: Assiming folks are taking as many responsible precautions as would be expected, is it better to get wasted by alcohol once a month or two or to take some lsd once a month or two? What about once or twice a year? These sorts of questions are closer to mimicking most folks' use of lsd.
But most folks use such things in a much more responsible manner. Occasionally. There will be outliers, just like alcohol. Most folks don't get addicted: 25% of heroin users might, and the rest is at 10% or less (Source: https://www.theguardian.com/society/2016/aug/26/neil-woods-u...).
As far as dangers are concerned: Part of the danger is not having honest sources and not having access to good information (think about how much more dangerous alcohol was during prohibition). Sure, there is a risk of addiction, but you have that with alcohol, prescription drugs, gambling, and a myriad of other things. Effects on society are heaviest on the illegal things because of the illegality. Current laws would cover a lot of the other 'dangers' much as they do with alcohol (don't be violent, take care of your kids, drive sober). We can regulate potency much like we do with alcohol. Sure, some things can be dangerous, but most folks aren't doing it in those ways. Just like alcohol. We just hear about the bad stuff more because of the political and moral stance on them.
