Firstly, to help if you're not a native English speaker, it's spelled cannabis. :) I am a frequent user (4+ times daily most days, for the past 2 or so years). I've never noticed a difference in my ability before or after smoking, vaping, or eating an edible (I take up to 100mg at a time). The only times I've ever had visual imagery are: a) while dreaming, but I lose the visuals after I wake; b) during a PTSD flashback, and then only on occasion, not every time; and c) this one time I took a mega dose of magic mushrooms and was able to see faint mandala/firework-like designs on the ceiling and when I closed my eyes. I've since started taking an antipsychotic, which treated my visual and auditory hallucinations, but I no longer get any effect from shrooms. :(
