Trayvon smoked pot at least four hours earlier according to the autopsy plus pot was in his blood gases which means he smoked it two weeks to a month before too. so it sounds like he was a regular user. Wonder how he paid for it since he couldn’t even stay in school much less have a job? Robbing houses, maybe?
Selling it is my understanding. I believe they have text and other messages suggesting he sold it. People frequently do that at the lowest 'retail' level in the black market to support their own use at no cost.
