For how long must the blue copy of the DEA 222 form be kept by the purchaser?

The blue copy of the DEA 222 form must be retained by the purchaser for a minimum of two years. This requirement is established under federal regulations that govern the purchase of controlled substances. The records need to be kept for this duration to ensure compliance with regulatory audits and to help track the distribution and use of these controlled substances. Maintaining accurate records is vital for accountability and to prevent misuse and diversion of these drugs.

The requirement of two years reflects the importance of having an adequate timeframe to monitor transactions involving controlled substances while balancing the record-keeping burden on pharmacies and other entities involved in the distribution of these medications. The law does not require an extension beyond this timeframe unless specified by additional state regulations or specific circumstances pertaining to particular substances.
