If my physician offered LSD to me, would want to be sure it was a last resort. Don't want to risk HPPD without good reason.

After experiencing very mild visual snow for a few months, that's frightening enough for me. My job is looking at a computer screen. I need my vision intact.

This happened to me. After one particularly intense trip I couldn't even look at a television for 6 months without having really jarring visual hallucinations. A few years of panic attacks too.

I quit taking LSD after that one and all psychoactives not much longer after.

Similarly, MDMA may cause (and does cause in many individuals) visual snow.

It went away? That's pretty uncommon from what I can tell.

I had a similar experience with a similar time frame. It didn't completely go away, but I stopped noticing it as much. Except for situations where it's hard to not notice like at night or when it's dark or I actively pay attention to it, I ignore it without having to think about it most of the time.
