i smoked a joint with 2 friends yesterday afternoon and woke up this morning with after effects...like i scratched my arm only i couldnt really feel myself scratching my arm... and if i bumped into something, i didnt really feel it. my reaction time was slowed too. is it normal to feel effects for this long? i also smoked again today almost 10 hours ago and am still feeling the same syptoms i was feeling this morning. how long will it take to go away??
