Brazil opens first 'ExpoCannabis' amid pot debate

Launched in Uruguay a decade ago, the huge marijuana fair opened its first international edition Friday in Sao Paulo, complete with DJs, guest speakers, myriad pot products and a large outdoor space packed with hundreds of visitors, nearly all of them smoking up.
