MADISON, Wis. — A bipartisan proposal designed to help Wisconsin’s fledgling hemp industry has been modified to appease concerns of law enforcement.

Police testified against the measure earlier this year because it prevented someone who had consumed a legal product made with trace amounts of THC, such as the hemp derivative CBD, from being charged with operating while intoxicated.

Instead, the bill as amended would put into law the current practice of allowing a driver to have a trace amount of THC in their blood, far below the level that is considered intoxicated. Wisconsin would join six other states with similar laws.
