Our input should help you decide whether you will grow and sell the marijuana or source the products from a grower and deal solely with retailing it at the dispensary.
Facts
Your boss at the clinic purchased a lottery ticket to reward you for being a hardworking employee. When the draw was done you became the winner of $500,000. You plan to reinvest the money into a marijuana dispensary. You have two options regarding operating the dispensary with the expectation to sell 10,000 ounces per year at $200 per ounce. The first option is to set up a growing and processing operation. The cost of operating the farm and other related costs is $800,000 and the retail store will cost $200,000. The expected profit from this option is $1,000,000 before federal taxes. The second option is to buy it from growers and sell it at the dispensary. Under this option, 10,000 ounces would be purchased at $900,000 and a rent of $200,000 paid for the retail store. The net profit before federal taxes is expected to be $900,000.
