Senator Dick Durbin (D-Ill) will introduce the first bill in the history of the U.S. Senate to provide an affirmative defense to medical marijuana users facing federal pot charges--the Truth in Trials Act. From the Marijuana Policy Project (MPP):

For the first time ever, a federal law recognizing the validity of state medical marijuana laws will be introduced in the U.S. Senate. U.S. Sen. Richard Durbin (D-IL) will introduce the Senate version of the Truth in Trials Act in October. Now is the time for you to write to your U.S. senators urging them to be original cosponsors of this medical marijuana legislation.

Please take two minutes to fax your senators a pre-written letter explaining why it is necessary to provide federal protections to patients and caregivers who use and provide medical marijuana in compliance with state laws. Visit here, enter your address, select a letter, and click a button to send it to your senators.

The Truth in Trials Act would create an affirmative defense that could be used against the outrageous federal prosecutions of patients and caregivers acting with the approval of state authorities and in accordance with state medical marijuana laws. The Department of Justice is holding medical marijuana patients in federal prison and actively trying to increase their numbers....It is urgent that your senators hear your outrage!
