Who retains the first copy of a DEA Form 222?

The supplier retains the first copy of a DEA Form 222 because this form is used to order Schedule I and II controlled substances. Once the order is filled, the supplier keeps the first copy for their records. This copy serves as documentation of the transaction and is important for both legal compliance and inventory tracking. The other copies of the DEA Form 222 are handled differently: the second copy is sent to the DEA to maintain regulatory oversight of controlled substances distribution, and the purchaser retains the third copy for their records. This system ensures proper accountability throughout the supply chain of controlled substances, reinforcing safety and regulatory compliance.
