The war between the federal government and the states of marijuana is about to explode with the Trump Administration preparing to be a lot harsher against hash than Obama was, and one battleground could prove pivotal in the coming years: Colorado. The state, one of several to legalize marijuana, is preparing an unusual strategy to counter the feds as they attempt to crackdown on pot, according to various news reports.

A bill that is making its way through the legislature there would reclassify recreational pot as medical pot to protect them from federal enforcement, a bold move that could cost the state millions of dollars in taxes. There are currently abou t500 licensed recreational marijuana dealers in the state, and the bill would reclassify them overnight, at a price tag of $100 million in lost taxes due to medical pot being taxed at a far lower rate.

And Colorado has reason to worry about a crackdown. Officials in Trump’s administration, including spokesman Sean Spicer, have suggested that marijuana is a scourge, particularly recreational marijuana.
