VICE News correspondent Nilo Tabrizy joined 'On The Line' to discuss the rapidly expanding legal marijuana industry. Marijuana is America's fastest growing industry. Last year, the legal market was valued at 2.7 billion dollars. But, marijuana is still illegal on the federal level, which has led to conflicting state laws, restrictive regulations, and endless problems for cash-only marijuana business owners and operators. Nilo Tabrizy traveled to Colorado and Canada for VICE News to explore the promises and perils of the bud business.
