ETA: ... an "anxiety attack"?!?!! ... from pot?!?!!? OOOOO-KKKkaaaayyyy, then ... )
Thanks to the Jamaicans, I think, this is known as a "whitey", coined after the white people who couldn't smoke as much as they could. What's actually happening is a blood sugar drop, as marijuana affects that. If it drops so much, it can cause an anxiety attack, which is what is happening in that 911 call I shared. But, this is easily avoided. Pace yourself and if you go off the deep end, eat some (non-laced) chocolate to bring your blood sugar levels back up. You'll be back to your Spongebob episodes, pizza rolls and peach Nehi in no time.
