So you basically did 6-7mg of LSD. Yes... that can mess you up long-term, but you won't know if it's permanent until a lot of time has passed. I don't think being 17 had much to do with it. It would mess up anybody. I don't care what anybody says, high dose LSD can alter brain structure. One time I accidentally did about 2mg from a concentrated liquid and it took me 3-6 months to return to normalcy. It didn't help that I was freaking out the entire time, which just made it worse. The brain responds to intense trauma with downregulation, it kind of "shrinks back." Trauma can cause brain damage. So I think that factored into it for me as well. I was able to still go to school and engage with my life, but internally I was not in touch with reality. I still debate to this day whether or not it was a psychotic break. If it was, it wasn't a traditional one. I think it just dissolved all internal frames of reference and I had a hard time getting grounded in a meaningful life after that. Everything just seemed like "oneness" and deconstructed into meaninglessness.
LSD clears the body within 90 minutes to 2 hours, but it leaves a powerful "echo" on neurology. The patterning continues to cascade until the nervous system settles into some kind of equilibrium; but if you've taken an extreme dose, the equilibrium may not look like the pre-LSD equilibrium. The 5HT2a receptors will have a different configuration from being broad-spectrum blasted by a high-dose sympathomimmetic serotonin analogue. With time the receptors will likely heal and go back to something resembling their near-original state, but you will be changed forever.
I have seen auras all my life around living things, but after that trip I started having phosphenism around every object, alive or not. It took about 10 years to fade away. I kind of learned to live with it but it sometimes got on my nerves, especially at night time because any light source would generate a lot of phosphenes in my vision. Other times, I enjoyed it. This is all to say, the brain is a remarkable organ and maybe in time it will heal. As a male, you don't stop fully developing until age 25. And the brain is pretty adaptive until after 35 when it starts to progressively slow down.
Side story, I once met a 35 year-old nurse when I was working in festival HR (she was my co-worker) who said that she used to live with a chemist who made LSD. One day he was dissolving a gram crystal of LSD in solvent, in the fucking kitchen. She thought it was a cup of water and drank part of it. She spat it out as soon as she realized it wasn't water, but had already swallowed some. She said that she was freaking out when the high started coming on. Then all she saw was white but after that she remembered nothing. The chemist sat with her and monitored her vitals for 12 hours without leaving, getting ready to call an ambulance. Apparently he said it looked like she was in a coma. She laid very still and was breathing very slowly. She woke up after 12 hours but it took her a week to feel somewhat normal again.
