it could of been many possible explanations of why he didnt get high most people dont get high until their second or thrid maybe forth time, it took me until my third time to get a high. maybe he wasnt inhailing correctly, i know when my friend did it for her fifth time everybody was saying she was inhailing correctly, but she didnt get high, and afterwards she found out what she was doing wrong. and maybe since it was his first time doing it he didnt know if he was high or not...but i think the real reason is because it was his first time...and most people dont get high until their third.
I smoked like 5-6 bowls at a time with this one guy. Finally, about the 7th time we smoked him up, he got high.
