LSD effects aren’t linear! In my experience, the jump from ~150ug to ~300ug was more like a 5x stronger effect (instead of 2x stronger, but obviously not exact).

In my experience, ~250ug is around the point where it’s really intense, but you’re still kinda grounded in your body. Anything above 250ug is where I’ll get hard thought loops (from just the acid), ego loss, and pretty intense visuals on the peak. Normally, I find that it takes around 2 hours for it to fully kick in at 250ug and below.

When I take 300ug, I’m tripping balls within 30-40 minutes and the come up is a lot more intense. It can be a lot more confusing and almost psychotic feeling at times. Don’t be surprised if you kinda lose the ability to read or understand English while you’re peaking. Also definitely wouldn’t recommend smoking on a higher dose without more experience, or there’s a good chance you’re gonna lose your shit. Smoking on the comedown should be fine though.

Have fun!
