Under 18 U.S.C. § 1461, it is a federal crime to knowingly place obscene material, or certain abortion-related items and information, into the U.S. mail. A first conviction carries up to five years in federal prison; any conviction after that carries up to ten. 1Office of the Law Revision Counsel. 18 USC 1461 – Mailing Obscene or Crime-Inciting Matter The statute descends from the Comstock Act of 1873 and remains actively enforceable today, with recent debate focused on how its abortion-related provisions apply to medication shipments.
What the Statute Makes Nonmailable
Section 1461 declares several categories of material “nonmailable.” The broadest sweeps in any obscene, lewd, lascivious, indecent, or filthy article, writing, picture, or substance. 1Office of the Law Revision Counsel. 18 USC 1461 – Mailing Obscene or Crime-Inciting Matter The language is deliberately wide, reaching every physical format. Because it applies to any “article, matter, thing, device, or substance,” it covers physical storage media like USB drives and discs that hold obscene digital files, just as it would a printed magazine.
A separate category targets abortion-related materials. The statute prohibits mailing any article or thing designed or intended for producing an abortion, any advertisement describing how to obtain such items, and any written material explaining how or where an abortion can be performed. 1Office of the Law Revision Counsel. 18 USC 1461 – Mailing Obscene or Crime-Inciting Matter Contraception was once on this list but Congress removed it in 1971, so the statute no longer covers birth control. 2Office of the Law Revision Counsel. 18 USC 1461 – Mailing Obscene or Crime-Inciting Matter
A companion statute, 18 U.S.C. § 1462, extends similar prohibitions beyond the Postal Service to private common carriers like FedEx or UPS and to interactive computer services used in interstate or foreign commerce. 3Office of the Law Revision Counsel. 18 US Code 1462 – Importation or Transportation of Obscene Matters Switching from USPS to a private courier does not take the conduct out of federal criminal law.
How Courts Decide What Is Obscene
Section 1461 does not define “obscene.” The Supreme Court did that in Miller v. California (1973), and the three-part Miller test still governs. Material is legally obscene only if all three of the following are true: 4Justia U.S. Supreme Court Center. Miller v California, 413 US 15 (1973)
- The average person, applying contemporary community standards, would find that the work as a whole appeals to a prurient interest in sex.
- The work depicts sexual conduct in a patently offensive way, measured against the applicable state law’s definition of such conduct.
- Taken as a whole, the work lacks serious literary, artistic, political, or scientific value.
The third prong is where most contested cases turn. Material with genuine literary, artistic, political, or scientific value cannot be obscene as a matter of law, no matter how explicit its content. The “community standards” element also matters in practice, because jurors apply the norms of their own community and those norms differ across federal districts.
What Prosecutors Must Prove
A conviction requires proof that the defendant knowingly used the mail to send material that qualifies as nonmailable. 1Office of the Law Revision Counsel. 18 USC 1461 – Mailing Obscene or Crime-Inciting Matter The word “knowingly” does real work, but less than defendants often hope.
In Hamling v. United States (1974), the Supreme Court held that the government does not have to show the sender knew the material met the legal definition of obscenity. It is enough that the defendant knew “the character and nature of the materials” being mailed. Awareness of the sexual content, combined with the act of mailing, satisfies the mental state. Ignorance of obscenity law is not a defense.
Genuine ignorance of what a package contains is different. A shipping clerk who sends a sealed box with no knowledge of its contents lacks the required awareness. For the abortion-related provisions, courts have read in an additional intent element: the sender must have intended the item to be used for an unlawful purpose, not merely mailed an item that could be used that way.
The offense is complete when the material is placed in the mail. Actual delivery is not required, so a package intercepted at a postal facility still supports prosecution.
Penalties, Fines, and Forfeiture
The statute sets a maximum of five years in federal prison for a first offense and ten years for any offense after that. 1Office of the Law Revision Counsel. 18 USC 1461 – Mailing Obscene or Crime-Inciting Matter Because Section 1461 says “fined under this title,” the general federal fine structure applies: up to $250,000 for an individual and up to $500,000 for an organization convicted of a felony. 5Office of the Law Revision Counsel. 18 USC 3571 – Sentence of Fine
The Federal Sentencing Guidelines fill in the range within those maximums. Under Guideline 2G3.1, the base offense level for mailing obscene material is 10, with enhancements that can push it much higher: 6United States Sentencing Commission. 2G3.1 – Importing, Mailing, or Transporting Obscene Matter
- Distribution for profit adds levels based on the retail value of the material, with a minimum five-level increase.
- Knowingly distributing obscene material to someone under 18 adds five levels.
- Using a misleading website domain to trick a minor into viewing harmful material adds two levels.
Conviction also triggers mandatory criminal forfeiture under 18 U.S.C. § 1467. The defendant must surrender the obscene material itself, any property traceable to gross profits from the offense, and any property used or intended to be used to commit or promote the crime. 7U.S. Government Publishing Office. 18 USC 1467 – Criminal Forfeiture In a commercial case, that can reach computers, vehicles, bank accounts, and real estate connected to the operation, well beyond the specific items mailed.
Medical, Educational, and Scientific Uses
Courts have long said Section 1461 was not written to stop doctors from sending medical information or researchers from exchanging scientific material. In Youngs Rubber Corporation, Inc. v. C. I. Lee & Co., Inc., the court wrote that “the intention to prevent a proper medical use of drugs or other articles merely because they are capable of illegal uses is not lightly to be ascribed to Congress,” and that the statute “has never been thought to bar from the mails medical writings sent to or by physicians for proper purposes.” 8Office of the Law Revision Counsel. 18 US Code 1461 – Mailing Obscene or Crime-Inciting Matter
The Miller test reinforces the point. Because material with serious scientific, educational, or literary value cannot be obscene as a matter of law, a medical textbook with graphic anatomical illustrations, a sex education manual, or a peer-reviewed study on human sexuality is protected. The relevant question is whether the material was created and distributed for a genuine purpose or whether a claimed educational purpose is a cover for commercial exploitation.
Abortion Medication and the Comstock Provisions
The abortion-related provisions of Section 1461 were largely dormant for decades but drew renewed attention after the Supreme Court overturned Roe v. Wade in 2022. Because the statute prohibits mailing articles “intended for producing abortion” and information on how to obtain or perform one, questions arose about whether the federal government could use it to block mailings of medication abortion drugs like mifepristone and misoprostol.
In December 2022, the Department of Justice’s Office of Legal Counsel issued an opinion concluding that Section 1461 “does not prohibit the mailing of certain drugs that can be used to perform abortions where the sender lacks the intent that the recipient of the drugs will use them unlawfully.” Because “there are manifold ways in which recipients in every state may lawfully use such drugs, including to produce an abortion,” the OLC reasoned, mailing them does not by itself establish the required criminal intent. 9U.S. Department of Justice. Application of the Comstock Act to the Mailing of Prescription Drugs That Can Be Used for Abortions
That opinion has not been formally rescinded as of early 2026, but it is executive branch guidance rather than binding law. A future administration could reverse the interpretation without any act of Congress, so anyone mailing these medications has reason to monitor DOJ policy.
Stopping Unwanted Sexually Explicit Mail You Receive
Section 1461 is a criminal statute, so it isn’t the tool for a private individual who simply wants to stop receiving suggestive advertisements. Federal law provides a separate mechanism for that. Under 39 U.S.C. § 3008, anyone who receives an advertisement they personally consider “erotically arousing or sexually provocative” can request a prohibitory order from the Postal Service. 10Office of the Law Revision Counsel. 39 US Code 3008 – Prohibition of Pandering Advertisements The standard is subjective: the recipient decides.
To request an order, submit PS Form 1500 at any post office and attach the offending mailpiece. 11United States Postal Service. PS Form 1500 – Application for Listing and/or Prohibitory Order The Postal Service then directs the sender to stop all future mailings to your address and to delete your name from any mailing lists it owns or controls. The order takes effect 30 days after the sender receives it, and you can include minor children under 19 who live with you. A related statute, 39 U.S.C. § 3010, requires senders of sexually oriented advertisements to include their name and address on the envelope and bars them from mailing to anyone who has been on the Postal Service’s opt-out list for more than 30 days. 12Office of the Law Revision Counsel. 39 US Code 3010 – Mailing of Sexually Oriented Advertisements Ignoring a court order to comply with a prohibitory order is punishable as contempt.
