Despite some recent baby steps, the untangling of the federal government's enduring and preposterous opposition to cannabis as a medicine or recreational substance is going to take a long, long time.
Nevertheless, I was delighted to read that the Senate had recently passed a bipartisan legislation loosening rules about cannabis research, "Cannabidiol and Marihuana Research Expansion Act." (The strange spelling has an unfortunate historical precedent.)
That is, until I spoke to a well-known cannabis researcher and a couple of attorneys who have sued the federal government on her behalf.
