Even though half the country has medical marijuana, states are still lookin for a way through this. You may legalize medical marijuana, and on the first day that sales begin there might be only a few dispensaries and grow operations that have actually opened. There may be lawsuits after licenses are awarded. Massachusetts has seen a ton of delays and now has only a half-dozen dispensaries have opened at this point. It serves as a warning. If you want to get into the business you need enough working capital to last a long time.
