Hi hi, I'm going to chime in.
I'll kick off by saying I'm not against it, but I can provide life experience that isn't going to match what people tend to say or think for that matter.
I'm one of the few people that had a legitimate "problem" with LSD and it's many derivatives, and while I don't have a problem with the decriminalization of it, I do have experience.
6 years of solid use of it worth of experience - literally. Every day, from 13 - 19 I was off my tits via it. You can toss in the occasional other substance, but Acid (the primary method of selling LSD at the time) was my main go to. It's best to consider this as me tripping my balls off 9 - 5 lol.
Obviously, as someone in the UK that means it covered almost all my time in high school through college and beyond.
While people will say you can't get physically dependent on it (aka what people consider addiction), you can very easily become psychologically dependent - something that seems to be an unspoken bullshit thing now. Just as much as you can easily become psychologically dependent on the weirdest off things. Even fapping can cause a psychological hook akin to addiciton. (lolol)
And as someone who had to go through rehab to get clear, that should say a lot.
Of course, I'm not going to say it's physically an issue, so long as you're mentally sound enough to keep a lid on it, but it can cause problems, and I've while I never had any particularly negative experiences during that time, I've known many people who werern't that lucky.
Past tense applicable because they're long dead.
Lets just say that what you read, and what you personally experience isn't necessarily tied to the outcome, and with LSD and things based on it you really do need to have a good head on your shoulders for it to not go wrong.
RIP all too many people.
I will rel-literate though, despite never personally having a negative experience, although having issues getting "free" from it; I've also had a lot of negatives due to people that weren't able to cope with what it entails.
Add that sadly there's far too many people that'll get dosed and hop in a car or do something else dumb that ruins it for everyone else.
On the other hand, I honestly wouldn't have made it through my teens without something; and despite the whole 'if you're in a bad frame of mind don't take it' rule that tends to be attached I not only got through a frankly shit period of life, I pretty much thrived during.
Feel free to say I'm biased, but I honestly don't regret it even after the hell of meeting reality after.
