That's heroin, right? We're Internet nerds, so don't ask us.
First, an obligitory display of minimal ethics: LeBron James is not really endorsing this heroin. These were found on a 19-year-old Philly drug dealer named Marlon Guess, as in "Marlon guessed it was a good idea to make his heroin brand way more noticeable than everyone else's." How much does LeBron go for? $750 for 140 packets (no, we have no idea how many "heroin doses" are in a "packet"). So that little baggie up there costs roughly $5.36, or about 1/56th the price of a pair of LeBron James sneakers. So how high does LeBron get you? Probably about as high as heroin.
