Colorado is working to becoming the first state to regulate production of medical marijuana. Regulators say pot consumers deserve to know what they're smoking, and producers should have safety regulations such as pesticide limits for plants destined for human consumption. Now, patients have no way to verify pot-shop claims that certain products are organic, or how potent a strain might be.
Colorado officials are having a tough time writing regulations for a product that's never been scrutinized or safety-tested before. New Mexico requires marijuana products to be labeled by strain and potency, and is planning to allow health inspectors to review samples. None of the 14 states that currently allow medical marijuana regulate how it's grown.
