21 USC 841(a) makes it unlawful, except as authorized, to knowingly or intentionally manufacture, distribute, dispense, or possess a controlled substance with intent to do those things. It also covers specified conduct involving counterfeit substances. The offense provision and the penalty provisions serve different functions: subsection (a) defines conduct, while subsection (b) supplies the relevant punishment. [1]
Possession and intent are separate issues
Simple possession is not automatically possession with intent to distribute. Evidence concerning quantity, packaging, communications, sales, and the surrounding circumstances can bear on the alleged purpose. The government must establish the charged offense; a person’s presence near drugs does not by itself answer every element.
Authorization matters too. The statute begins with an exception for authorized conduct, but a professional title or registration should not be treated as permission for every distribution. Evaluate the specific conduct and legal authorization rather than relying solely on the person’s occupation. [1]
Read the correct penalty tier
For many common trafficking prosecutions, subsection (b)(1)(A) establishes a ten-year-to-life range at its specified drug quantities, while subsection (b)(1)(B) establishes five to forty years at its thresholds. Subsection (b)(1)(C) often supplies a maximum of twenty years for covered substances outside those higher quantity tiers, subject to its own exceptions and enhancements. Other substances and marijuana provisions have different rules. [1]
These are not interchangeable quantity labels. Actual methamphetamine and methamphetamine mixtures have different thresholds, for example. Death or serious bodily injury and qualifying prior convictions can also change the range. A statute-wide summary should never replace reading the exact charged subparagraph.
Conspiracy and sentencing relief
Section 846 subjects attempts and conspiracies to the penalties for their object offense. It is therefore possible to face serious trafficking penalties on a conspiracy charge even without a completed personal sale. The actual agreement and legally attributable conduct still need to be established. [2]
The federal safety valve can permit sentencing without an otherwise applicable mandatory minimum when every statutory requirement is satisfied. Its criminal-history, weapon, injury, leadership, and disclosure conditions require separate review; pleading guilty is not enough. [3]
Ask counsel to distinguish the statutory range, the guideline calculation, any enhancement procedure, and available relief. See Section 841(b)(1)(B)'s five-to-forty-year tier and criminal forfeiture under Section 853 for two additional parts of a federal drug case.
