I agree with the poster above. Having dilated pupils isn't really a problem as long as there is not much pain and your vision hasn't changed much.
I have bright bluish grey eyes and when i'm inside, be it high or sober, my eyes dilate so much they look pitch black. Then I go outside and my pupils shrink to the size of a pin point and the color of my iris's come out.
but this is what is most important to me about ur case, if it is just ur pupils ur most likely fine, however the pupils reflect what is going on in the brain. Have a friend get a small pen light and test out ur pupil response. U can even try this in a bathroom. Turn off the lights, ur pupils will explode, and while peering in the mirror turn them back on quickly and ur eyes/pupils should adjust drastically then settle in back to normal. If this is not occurring u r having an underlying neurological issue. Not that it is serious and u will go blind, but u should go to an eye doc tell them about all drug use (docs are pro drugs haha and they cant report u for illegal ones if no crime is involved at that moment) and see if ur optic nerve and back of ur eye are in good shape. But thats only if u have delayed or no pupil response to a pen light etc.
