How to tell if someone smokes a ton of pot

[Undertoad]

After a decade of answering the phone calls of troubled teens and young people, Dr. Drew and Adam Carolla determined that serious stoners have a particular hiccup-y style of laughing.

It became comical, because they would hear the laugh and immediately tell the caller, wow, you smoke a ton of pot. And the caller would immediately confess to it, and the radio listener would immediately say, wow, that's magic, how did they know that?

This is that laugh. Anyone who laughs like this smokes a ton of pot.
