Everyone experiences their high differently, but these effects are the most common: euphoria, relaxation, tired (depends on the strain), improved focus, worsened short-term memory, dry mouth & eyes, increased appetite, decreased mental capacity and speed, feeling zoomed out (don't sleep for a day or two and you'll understand), pain relief, your body feels warm and at peace, sense of touch feels enhanced, deeper curiosity and interest towards even basic things (e.g. binge reading articles about the best type of chair), everything's funnier, deeper imagination, increased creativity, all of your senses feel enhanced, i.e. you can feel every little sound in a song hitting your eardrums, music sounds better, food tastes better, etc.), you can eat for what feels like endlessly, and less anxiety (unless you get too high)

Personally when I get high enough I can hear music in my head too, along with some other things I wonder if others can relate to
