dude one time my gf took the biggest rip off this bong i made, and she was higher than hell the rest of the night. it was too much though, becuase she was literally having a total panick attack; shivering, shaking, delerious, and her heart felt like a toad bouncing for dear life inside of her rib cage. me and my friend also got murdered from one hit each, only we didnt fall over the edge like she did. i think it was just cuz shes smaller.
