Three of the four marijuana-centered lawsuits filed against Colorado officials and businesses were organized and at least partially funded by out-of-state anti-drug organizations and socially conservative law firms. Only one lawsuit, filed by the states of Nebraska and Oklahoma, appears to be entirely homegrown. For those who oppose Colorado's marijuana laws, the out-of-state money offers a chance to fight back against what they characterize as a well-heeled marijuana lobby that changed public opinion with misleading messages.
