Cannabis is being legalized across the U.S. and some entrepreneurs have been waiting for years for that moment. The trend is now triggering a lot of entrepreneurial innovation. Here is a company promising to introduce cannabis coffee pods that will be compatible with familiar Keurig machines. The pods will contain a mixture of caffeinated coffee and cannabis flower. Each cup of the initial product will contain 10 milligrams of THC, the active marihuana ingredient, for recreational users, and up to 50 milligrams for medical users.
