Most pharmacies spend a lot of time evaluating generic pricing and delivery timelines when they’re shopping for a new distributor. That’s fair. But when it comes to controlled substances, those aren’t the questions that will keep your license intact.
Schedule II through V drugs carry a different kind of weight. The DEA watches this supply chain closely. One weak link, whether that’s on your end or your distributor’s, can escalate into something far more serious than a fine. Pharmacies that get ahead of this ask the right questions before they sign anything.
Here’s where to start.
Does the Distributor Actually Have the Right Licenses?
It sounds basic. It gets skipped more than you’d think.
Every distributor working with controlled substances needs an active DEA registration covering Schedule I through V. They also need valid wholesale distribution licenses in each state they’re shipping to, not just their home state.
Before anything else, ask for that documentation. Then go verify it yourself through the DEA’s Diversion Control Division. Don’t take a PDF at face value. Legitimate drugs distributors hand this over without hesitation. Delays or runarounds on a licensing question say something.
NABP accreditation is worth looking for too. It’s not a legal requirement, but it shows the distributor is being held to a standard beyond the minimum.
How Do They Handle Suspicious Order Monitoring?
The Controlled Substances Act puts a real legal duty on distributors to flag and then report orders that look, a little, out of the ordinary—maybe a weird volume, strange ordering patterns or a frequency that just doesnt line up with a pharmacy profile. People call this a Suspicious Order Monitoring system, SOM, and it kind of acts like a radar for those odd things.
A lot of distributors have one on paper. Fewer have one that actually works. So push past the surface answer and ask:
- What specifically triggers a review in their system?
- Who’s responsible for looking at flagged orders?
- Is there a hard stop on suspicious orders, or just an internal note?
- How quickly does a flagged order get escalated to the DEA?
The opioid litigation that wrapped up in 2021 made one thing very clear. Some of the biggest drugs distributors in the country had SOM systems that were essentially decorative. Pharmacies tied to those distributors didn’t escape scrutiny either. You don’t want to inherit someone else’s compliance failure.
Are They Actually DSCSA-Compliant, Not Just Technically?
Since 2025, full enforcement of the Drug Supply Chain Security Act means every distributor in the chain needs unit-level serialization and the ability to share complete transaction records electronically.
The documents to ask about are TI, TH, and TS — Transaction Information, Transaction History, and Transaction Statement. These should accompany every controlled substance shipment, without exception.
Beyond that, ask whether their system actually talks to your dispensing software. Ask what happens when a serialization scan doesn’t match. A distributor who fumbles that question, or gives you a vague answer, probably hasn’t dealt with a real traceability mismatch yet. That’s worth knowing before you’re in the middle of one.
- Can they produce full transaction documentation per shipment?
- Do they support electronic verification at the pharmacy level?
- What’s their process for flagging and resolving traceability discrepancies?
Traceability isn’t administrative overhead. It’s what stops diverted or counterfeit product from making it to a patient.
What Do Their Storage and Security Setups Look Like?
DEA regulations are specific about how controlled substances get stored. Vault and cage requirements exist for a reason. Your distributor’s warehouse needs to meet those standards, and you should know what those standards look like before assuming they’re met.
Ask about:
- Physical access controls and alarm systems in their storage areas
- How often they do inventory reconciliation on controlled substances
- Their process for reporting losses or thefts to the DEA
On the theft reporting piece, the legal window is tight. Significant losses have to be reported to the DEA within one business day, so yeah ask them how they handle that, in real life not just what the policy doc says. Â
Also check whether they carry cargo insurance that covers controlled substance loss in transit. A lot of pharmacies don’t think to ask this until something actually goes missing.
Is Their Pricing Too Good to Be True?
DEA production quotas, manufacturer caps, and demand swings make the controlled substance supply genuinely unpredictable, like you know it can change fast. Good drugs distributors are honest about that. They also won’t promise you steady availability of a product they really can’t guarantee. Â
And when the pricing lands noticeably lower than what you’re seeing elsewhere, it’s worth asking why. Gray-market sourcing and unauthorized channels do exist in this area. A price that looks like a deal can come with sourcing you don’t want attached to your DEA number.
Ask directly:
- Which manufacturers are they sourcing from for the specific products you need?
- Are they an authorized distributor for those manufacturers?
- Do they have a written allocation policy when supply runs short?
That last one is something most pharmacies forget to ask. When there’s a shortage, smaller accounts often get pushed to the back. Knowing whether that’s their default practice matters.
What’s Their Response When Things Go Wrong?
Controlled substance distribution isn’t a space where everything always goes smoothly. Shipments come up short. Products get recalled. Diversion incidents happen. The question isn’t whether a distributor has ever had a problem. It’s how they handle one.
Ask:
- What’s the step-by-step process if a shipment arrives with a discrepancy?
- How do they manage a DEA-mandated recall on controlled substances?
- If a pharmacy raises a diversion concern, what happens and how fast?
The answers here are more telling than any policy document. A distributor who walks you through a clear, practiced process has dealt with real situations. One who gives you a generic answer probably hasn’t, or hasn’t handled it well.

Frequently Asked Questions
- Are all pharmaceutical distributors required to have DEA registration to distribute controlled substances?
Yes. Any distributor handling Schedule I through V substances needs an active DEA registration and current state-level wholesale licenses in every state they operate. Verify this directly before signing any distribution agreement.
- What is a Suspicious Order Monitoring system and why should pharmacies care?
An SOM system is how distributors track and report orders that look unusual in volume, pattern, or frequency. If your distributor’s SOM is weak or inconsistent, your pharmacy can get pulled into a compliance investigation even if you did nothing wrong. It’s your supply chain. That risk is real.
- What transaction documents should a distributor provide under DSCSA for controlled substances?
They should provide Transaction Information , Transaction History, and a Transaction Statement with each shipment. These records kinda confirm the full chain of custody from the manufacturer all the way to your dispensing system.
- What should a pharmacy do if a distributor’s controlled substance pricing seems unusually low?
Ask where the product is sourced confirm the distributor holds authorized status with that manufacturer, and compare against market pricing from other reputable drugs distributors. Low pricing in this category sometimes points to sourcing you don’t want attached to your license.
