Section 846 of Title 21 prohibits conspiracies and attempts to violate any substantive offense established by Subchapter I of Title 21 ("Control and Enforcement")—in other words, Section 846 makes it a crime to conspire to violate or attempt to violate any substantive offense set forth in 21 U.S.C. §§ 801-904. Analogously, Section 963 of Title 21 prohibits conspiracies and attempts to violate any substantive offense established by Subchapter II of Title 21 ("Import and Export")—in other words, Section 963 makes it a crime to conspire to violate or attempt to violate any substantive offense set forth in 21 U.S.C. §§ 951-971.

The general conspiracy statute (18 U.S.C. § 371) may not be used to charge a conspiracy involving those sections. See Principles of Federal Prosecution, JM 9-27.300 ("Once the decision to prosecute has been made, the attorney for the government should charge and pursue the most serious, readily provable offenses.").
