I am 18 and have taken lsd about 8-9 times in the course of a half year. I have noticed after a really intense 200ug acid trip that i had very light tracers when i wave objects and my hands in front of my face. Colors dont blend together but they do seem more vibrant than normal. I dont have anxiety or feel depersonalized. At this point it has been about a month since these my last trip and the onset of these minor symptoyms. Now i am curious do i have hppd of some sort?
