not true, at least for me, ive hallucinated twice and ive been smoking for a while and ive had lots of different kinds i had some g-13 almost a half of it and i smoked as much as i could, at a certain point you just get too high and it felt like my nerves were so high strung that i was gonna snap and freak out, and that feeling mixed with some heavy random paranoid behavior. it was stupid as hell, then i kept that up though i just kept smoking more and more until finally i think i smoked myself sober. i felt completly sober in all aspects and so i just though SHIT what a waste of weed and then i went to bed.....
