This isn’t a told-you-so. Yet. But it’s a good way to bet:
Votes making Colorado and Washington the first U.S. states to legalize marijuana for recreational use could be short-lived victories for pot backers because the federal government will fight them, two former U.S. drug control officials said on Wednesday.
They said the federal government could sue to block parts of the measures or send threatening letters to marijuana shops, followed up by street-level clampdowns similar to those targeting medical marijuana dispensaries the government suspects are fronts for drug traffickers.
