Researchers from The ArcView Group, a cannabis industry investment and research firm based in Oakland, California, found that the U.S. market for legal cannabis grew 74 percent in 2014 to $2.7 billion, up from $1.5 billion in 2013. As America’s fastest growing industry, business professionals of all ages and backgrounds are trying to join the green rush.

There are many of opportunities to break into the legal industry from startups to consultant positions, but there are still many challenges due to lack of research on the once taboo topic. Prestigious universities, such as Northeastern and University of Vermont, are starting to offer courses investigating the science and the uses of medical marijuana. This is a good step to turn the once naive consumers, employees and entrepreneurs into educated professionals.
