This week, cannabis company Terra Tech announced it is expanding its retail operations in Southern California. Derek Peterson, President and CEO of the company, has led his company to $7.8 million in quarterly revenue. Peterson says he's seen a big paradigm shift over the last two years in the marijuana space. Greater access to capital is creating a lot of opportunity for new business and innovation in this space. One way Terra Tech is capitalizing on this trend is by expanding its retail footprint in California and Nevada.
