DENVER — What's in that joint, and how can you be sure it's safe?
Colorado is working toward 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.
Right now, patients have no way to verify pot-shop claims that certain products are organic, or how potent a strain might be.
"You don't go into a Walgreens with a headache and put on a blindfold and pick something off a shelf. But that's what some people are doing when they buy marijuana," said Buckie Minor of Full Spectrum Laboratories in Denver, which does voluntary marijuana analysis for about 100 growers and dispensaries.

Colorado officials are having a tough time writing regulations for a product that's never been scrutinized or safety-tested before.
