A 33-year-old Kalispell man has been arraigned on federal drug and money laundering charges after raids of medical marijuana businesses last spring.

The U.S. Attorney's Office says Christopher Durbin appeared before U.S. Magistrate Judge Jeremiah Lynch Wednesday and pleaded not guilty to charges of conspiracy to manufacture and distribute marijuana, possession with the intent to distribute marijuana and conspiracy to launder money.

Durbin also denied a charge of structuring, or making bank deposits of less than $10,000 in order to avoid IRS reporting requirements.

He was charged after a raid on Good Medicine Providers in Columbia Falls. He is detained.

Co-defendants Aaron Durbin and Justin Maddock pleaded guilty Tuesday to conspiracy to manufacture marijuana.
