A person does not automatically become a member of a federal drug conspiracy merely because he buys or sells illegal drugs. Every drug sale necessarily involves an agreement between a buyer and seller, but federal conspiracy law requires an agreement to participate in a broader criminal objective.
The distinction can be extremely important. A defendant charged with a federal drug conspiracy under 21 U.S.C. § 846 can face serious penalties based on the scope of the alleged conspiracy and the quantity of drugs attributed to the offense.
The law concerning the difference between a buyer seller relationship and a drug conspiracy has also changed significantly in the Seventh Circuit.
What Must the Government Prove in a Federal Drug Conspiracy?
Under 21 U.S.C. § 846, federal prosecutors may charge a person with conspiring to commit a federal drug offense.
A conspiracy requires an agreement between two or more people to commit the underlying crime. In a drug distribution case, the government ordinarily attempts to prove that the defendant knowingly joined an agreement involving the distribution of controlled substances.
Mere association with drug dealers is not enough.
Likewise, simply knowing that another person is involved in criminal activity does not necessarily make someone a member of that person’s conspiracy.
The government must prove the defendant knowingly participated in the criminal agreement charged.
The Buyer-Seller Rule
The buyer-seller rule recognizes an important distinction in federal conspiracy law.
A simple agreement to buy and sell drugs does not automatically establish a separate conspiracy to distribute those drugs.
Otherwise, virtually every drug transaction could automatically become a conspiracy prosecution.
The issue is whether the evidence shows something more than the agreement inherent in the sale itself and supports the conclusion that the defendant knowingly participated in a broader drug distribution conspiracy.
United States v. Pulgar
The Seventh Circuit addressed this issue in United States v. Pulgar, 789 F.3d 807 (7th Cir. 2015).
Herberto Pulgar sold substantial quantities of cocaine to another individual over approximately 11 years.
The government argued that the lengthy relationship, quantity of cocaine, alleged credit transaction, returns of poor-quality cocaine, and friendship between the men established a conspiracy to distribute cocaine.
A jury convicted Pulgar of conspiracy.
The Seventh Circuit vacated the conviction.
At the time, the court concluded that the evidence was just as consistent with a long-term buyer-seller relationship as it was with a drug distribution conspiracy.
The court emphasized that repeated sales, even involving substantial quantities of cocaine, did not necessarily establish the separate agreement required for conspiracy under the Seventh Circuit law then in effect.
The Seventh Circuit Changed the Law in 2024
The Seventh Circuit subsequently reconsidered its buyer-seller cases.
In United States v. Page, 123 F. 4th 851 (7th Cir 2024) decided by the Seventh Circuit en banc in December 2024, the court altered key aspects of its prior buyer-seller analysis.
The court expressly overruled Pulgar and several related decisions to the extent those cases were inconsistent with the new standard.
That change is important for anyone relying on older Seventh Circuit buyer-seller cases.
A defendant can no longer safely argue that repeated transactions involving distribution quantities are insufficient merely because the government lacks additional evidence such as sales on credit, consignment arrangements or other traditional indications of cooperation.
Repeated Distribution Quantity Transactions Can Matter
Under the Seventh Circuit’s current approach, evidence of repeated transactions involving distribution quantities of drugs can support an inference that the parties agreed to participate in a drug distribution conspiracy.
This does not mean every buyer-seller relationship is automatically a conspiracy.
The basic distinction still exists.
A simple purchase or sale does not necessarily prove that the parties agreed to participate together in a broader distribution venture.
But the nature, quantity and frequency of the transactions can provide circumstantial evidence from which a jury may infer the required conspiratorial agreement.
That makes the factual circumstances of the transactions particularly important.
Evidence Prosecutors May Use to Prove a Drug Conspiracy
Federal drug conspiracy cases are frequently proved through circumstantial evidence.
Depending on the case, prosecutors may rely on evidence such as:
Repeated purchases involving distribution quantities of drugs
Sales on credit or consignment
Fronting drugs for later payment
Coordinating customers or suppliers
Sharing information about law enforcement
Providing assistance in distributing or storing drugs
Using middlemen or couriers
Sharing profits or paying commissions
Recorded calls and text messages discussing drug distribution
Testimony from cooperating witnesses
No single fact necessarily decides whether a conspiracy existed. The government will generally ask the jury to consider the evidence as a whole and infer that the defendant knowingly participated in the charged agreement.
Drug Quantity Alone Can Have Serious Consequences
Drug quantity can affect much more than whether prosecutors attempt to prove a conspiracy.
Under 21 U.S.C. § 841, the type and quantity of controlled substances involved in an offense can trigger significant statutory penalties.
In a conspiracy case, disputes can also arise concerning which quantities of drugs can legally be attributed to an individual defendant.
A defendant should not automatically be held responsible for every drug transaction committed by every person associated with an alleged conspiracy.
The scope of the defendant’s agreement and the applicable rules governing the attribution of drug quantities must be examined carefully.
Cooperating Witnesses in Federal Drug Conspiracy Cases
Federal drug conspiracy prosecutions frequently depend heavily on testimony from cooperating witnesses.
A cooperating witness may have been arrested and agreed to provide information to the government in exchange for the possibility of receiving favorable treatment.
That does not automatically make the witness’s testimony false. But it creates important issues for the defense to investigate.
The defense should examine prior inconsistent statements, plea agreements, benefits expected by the witness, criminal history, recorded communications, and whether independent evidence corroborates the witness’s account.
In some cases, the government’s claim that a defendant joined a conspiracy may depend substantially on how a cooperating witness characterizes what were otherwise ordinary buyer-seller transactions.
Defending a Federal Drug Conspiracy Charge
There is no single defense to every federal drug conspiracy prosecution.
The defense should examine precisely what agreement the government alleges existed and what evidence supposedly establishes that the defendant knowingly joined it.
Potential issues can include whether the evidence proves only purchases or sales, whether the alleged transactions involved personal use or distribution quantities, whether cooperating witnesses are credible, whether the government can prove the alleged drug quantities, and whether intercepted communications actually demonstrate participation in the charged conspiracy.
Search warrants, wiretaps, confidential informants, controlled purchases and statements obtained by federal agents may also present separate constitutional and evidentiary issues.
Older Buyer-Seller Cases Must Be Used Carefully
Older Seventh Circuit decisions remain useful for understanding the development of the buyer-seller doctrine, but they must be read in light of the Seventh Circuit’s more recent en banc decision.
Pulgar remains an important example of the distinction courts historically drew between drug transactions and conspiracy.
But a defendant or attorney should not rely on the old Pulgar formulation without considering the Seventh Circuit’s 2024 change in the law.
That distinction is particularly important because older internet articles and case summaries may continue to describe rules that no longer accurately reflect current Seventh Circuit law.
