I could just never justify the risk when it comes to the bigger stuff.
Yeah you might have some of the best experiences/feelings of your life, but there is the off chance that even if done safely and conscientiously you can die.
I prefer to have a consistently decent life than a super duper few years ending in a heart attack.
I didn't really make it clear, I'm not some fucking pill head that does this stuff all of the time. I don't actually like coke. I think I'm done with MDMA, it just fucks you up too much - I had a patch of anxiety and panic attacks when I was stupid and did too much one night, and though those effects have subsequently dissipated, I learned my lesson and haven't had such effects since. Another reason to be done with it is, as you say, that it greatly increases the risk of heart problems.
LSD, on the other hand, is widely misconceived to be the direct instigator of mental illnesses. Recent studies show that the risk to mental health is far lower than previously thought, and evidence suggests that used in the right way, it can be used to treat PTSD and anxiety.
If your family has a history of mental disorders such as schizophrenia, taking LSD can be a contributing factor in the development of such conditions. However, the probability and actual frequency of these events occurring is greatly exacerbated by stories of stars such as Syd Barrett. The reality is in most cases, is that they took too much - they pushed themselves too far.
Another point I'd like to mention, is that It doesn't put me in a funny mood for days whenever I take it, the comedown is far better than that of alcohol. In fact, I usually feel pretty centred for weeks after taking it.
Another thing - LSD is pretty much harmless to the body, with the exceptions of respiratory system damage from taking too much too often. To be quite frank, the damage it does to the large majority of people is far less than that of a night drinking too much.
MDMA, Coke, speed and other amphetamines, on the other hand, do put a lot of strain on the body and heart. LSD does not, hence my liking to it.
I saw a chart informing users of the dangers various drugs pose to the consumer, and LSD and Mushrooms were right at the bottom, with alcohol somewhere in the middle, and MDMA and other amphetamines at the top.
I just want to experience new things, new ways of thinking, new perspectives, and LSD is definitely one of the things that can help to do that. Once of my friends tried it for the first time recently with me, and he's not usually the kind of person to do this thing, but I had a feeling he might like it. I will also say that I did not pressure him, I asked him if he'd be up for trying a small amount, and he agreed. At first, he approached it with his usual skepticism, and he didn't like it so much. As the night went on, he came to understand how it works and how it affects your thinking, and he was very much enjoying it. And he said, "thanks for that tab man, it's given me some interesting insights, I've actually learned some stuff about myself".
It's not really something that can be explained, only experienced. But although I doubt I'll ever convince you to try it, I just hope I can convince you of its grossly misplaced distrust.
Though, to be quite fair, the fact that you're worrying about what it'll do to your body is probably a sign you shouldn't take it. Taking this stuff with a paranoid voice in the back of your head telling you it's going to kill you will only end in more paranoia.
