Colorado Criminal Defense Attorney writes on his blog about IRS Audits of Marijuana Dispensaries that they may be a part of the way the United States Government is responding to recent changes in state laws regarding the possession and use of Marijuana. Colorado, Washington and California are three states have made marijuana legal. These amendments are not in accordance with Federal Narcotics Laws. So Federal Charges may be levied against those in possession of or manufacturing marijuana, especially in large amounts.
The Federal Authorities said they are not doing this, however an IRS audit often begins with an IDR or Information Document Request . This often gives way to the discovery of criminal activity leading to federal charges against the Marijuana Dispensaries.
