In many states, medical cannabis programs are the only way to legally acquire cannabis. In these states, the end customers are patients looking for relief from their suffering. They have turned to cannabis for a variety of reasons, but they can probably all agree that they expect a high-quality product that is all-natural, and free of impurities such as mold, bacteria, and pesticides. After all, conventional pharmaceuticals are produced under strict clean room conditions, leaving little doubt regarding the quality of the medicine received. Cannabis should be no different. In order to protect patients, and meet a growing demand, quality control needs to be a top concern for growers, investors, and the end user.
