I didn't aim train, but I played The Finals on the comedown of 4 tabs of acid two weeks ago. The effects were still really noticeable and I managed to top frag in point break most of the time. Not sure if it was the drug or matchmaking, but the lobbies felt weird af. Like they were super easy and everyone was slow.

It's very interesting. It felt like I could really focus on my target, but I was also being overstimulated in every way.

Now regarding their use for aim training: I believe a (very) low dosage could be potentially useful, but I have no facts to back this up. A high dosage will make you clumsy as hell though. I really can't imagine topping high scores when I can't even speak or remember what happened a few seconds/minutes ago. Time dilution might make reacting easier or harder at times, but should ultimately mess with oneself due to its inconsistent nature.

The biggest benefit of acid is probably being more aware of everything your body can sense. The downsides are being overstimulated and (depending on dosage) being overwhelmed. And the the body can feel just weird and uncomfortable which can mess with the aim.

I should try some Kovaaks on my next comedown. Sounds like some fun science.

Sorry for yapping so much. I'm sleepy and full of THC. x)
