21 U.S.C. 846 punishes attempts and conspiracies to commit covered federal drug offenses using the penalties prescribed for the underlying offense. A completed sale is not required to establish a conspiracy, but the government must establish the unlawful agreement and the defendant’s knowing participation. [1]
Association is not the agreement
Being present, knowing a participant, or communicating with someone later accused of trafficking does not by itself prove membership. The complete evidence must show the legally required connection to the shared unlawful objective. Messages, transactions, recorded conversations, and conduct can provide evidence, but context matters.
Identify the underlying offense
Section 846 does not supply one fixed sentence for every conspiracy. The object offense, drug, quantity, qualifying priors, and other legally required findings affect the statutory range. Section 841 contains many of the underlying distribution penalties. [2]
For example, the size of an entire organization’s operation does not eliminate the need to determine the findings legally attributable to a particular defendant for the applicable sentencing issue.
Keep liability theories separate
Conspiracy, aiding and abetting, and liability for another participant’s acts have different requirements. A guilty plea should identify the actual agreement and consequences rather than rely on a general statement that the accused “was around drugs.”
A formal contract or completed transaction is unnecessary
The alleged agreement can be proved through circumstances, but the government still must show the required knowing participation. A defendant need not know every participant or every detail to join a qualifying agreement. Conversely, a purchase or conversation should not automatically be converted into the broader agreement alleged without examining context. In United States v. Shabani, the Supreme Court held that section 846 does not require a separate overt act as an element. Do not import that requirement from a different conspiracy statute. [3]
For sentencing, identify which drug and quantity findings affect the particular defendant rather than merely repeating the organization’s largest alleged total. A plea discussion should distinguish admission to the agreement from admission to every transaction, enhancement, or disputed sentencing fact. [1] [2]
Preserve communications, transaction records, search materials, and evidence that clarifies the person’s actual role. See section 841(a)(1) charges and co-conspirator statements at James hearings for the substantive offense and evidence issues commonly accompanying conspiracy allegations.
