A Colorado proposal to certify organic marijuana has been rejected amid concerns the labels would imply pot is healthy.

The bill rejected in a legislative committee Tuesday would have created a first-of-its-kind label for marijuana that had been produced without pesticides.

Republicans voted against the measure, saying it could wrongly imply that marijuana is healthy. Other lawmakers worried that the U.S. Department of Agriculture would penalize state agriculture regulators for labeling pot as organic.

Colorado would have been the first state to regulate organic labels in its pot industry.

Sponsors said that consumers are currently confused about organic marijuana claims.

Organic standards are regulated federally, and pot remains illegal at the federal level, meaning there's nothing stopping commercial pot growers from calling their wares organic.
