What state did he get arrested in? Was it packaged for resale? Did he traffic it across states/countries? Either way, he's pretty fucked.
Texas. It was mexi brick that was in multiple different bricks. Even if it was in 1 big brick good luck convincing anyone you have 500ibs in your truck for personal use. Also his record isn't clean and he has thug ass tattoos all over him further worsening the situation.
http://norml.org/index.cfm?wtm_view=&Group_ID=4566 sounds like he might be in for it, especially if he has a record and tbh, it's gonna be hard to convince someone you're buying 500 lbs. for personal use.
He is so fucked...I wish him well, because he doesn't deserve jail for that. Real criminals and violent offenders belong behind bars.
