Colorado starts work Friday on becoming the first state to regulate organic labels in its pot industry, with other legal weed states watching to see whether they too should step in to help consumers wondering what's on their weed.

Two marijuana users in Colorado filed a lawsuit Monday against a pot business they said used an unhealthy pesticide to grow their weed — a case that lawyers say is the first product liability claim in the nation involving the legal marijuana industry.

An accounting error in Colorado is paying off for marijuana consumers Wednesday, when a quirk in a state tax law prompts the state to suspend most taxes on recreational pot.
