Federal Criminal Charges for GBL, Ketamine, and Other Club Drugs in New York City

The author of this article, Matthew Galluzzo, is a former Manhattan prosecutor and experienced federal criminal defense attorney who has successfully defended individuals accused in federal and state courts of possessing and distributing drugs and controlled substances commonly found in New York City nightclubs including ketamine, GHB, GBL, crystal meth, cocaine, MDMA, molly, and others. If you (or a loved one) have been arrested in connection with such an offense, you should strongly consider contacting him to discuss his engagement.

New York City’s nightlife and club scene has long been associated with a wide range of recreational drugs. Some substances that appear in nightlife settings—including GBL and ketamine—can also create significant federal criminal exposure when they are possessed, distributed, imported, or sold.

The federal government does not generally prosecute every person found with a small quantity of a controlled substance. But federal jurisdiction can become particularly important when prosecutors allege distribution, trafficking, conspiracy, importation, large quantities, online sales, or conduct resulting in serious injury or death.

Recent federal prosecutions demonstrate that these cases are not merely theoretical. In June 2026, for example, the U.S. Attorney’s Office for the Southern District of New York announced charges against two Manhattan men accused of conspiring to distribute millions of doses of GBL throughout the New York City area. Prosecutors alleged that the defendants had imported more than seven U.S. tons of GBL between 2023 and 2026. Each defendant was charged with conspiracy to distribute GBL, carrying a statutory maximum of 20 years in prison.

For individuals involved in nightlife-related drug cases, understanding the distinction between simple possession and distribution, as well as the different federal penalties associated with each, can be critical.

GBL: A Particularly Serious Federal Drug Charge

Gamma-butyrolactone (GBL) is an industrial chemical that has legitimate uses as a solvent and in manufacturing. It is also metabolized by the body into GHB and is sometimes sold illicitly as a recreational drug.

The DEA describes GBL as an analogue commonly substituted for GHB. Federal law treats GBL differently depending on the circumstances, and the substance has also been regulated as a List I chemical. The DEA has specifically described illicitly sold GBL as a Schedule I controlled substance.

That distinction can be extremely important in a criminal case.

Possession of GBL

A simple-possession prosecution generally falls under 21 U.S.C. § 844 when the substance is treated as a controlled substance. The statute prohibits knowingly or intentionally possessing a controlled substance without authorization.

For a first offense under § 844, the maximum term of imprisonment is generally one year, with a minimum fine of $1,000. A prior qualifying drug conviction can increase the maximum to two years, while two or more prior qualifying convictions can increase the maximum to three years.

GBL cases can be more complicated, however, because the federal government may characterize the substance under different provisions depending on its chemical status, intended use, and the government’s theory of prosecution.

Distribution of GBL

The potential penalties become substantially more serious when prosecutors allege that a defendant distributed GBL rather than merely possessed it.

Under 21 U.S.C. § 841(a), it is unlawful to knowingly or intentionally manufacture, distribute, dispense, or possess with intent to distribute a controlled substance.

Section 841 also contains a particularly important provision concerning substances associated with sexual assault.

Federal “Date Rape Drug” Provision

21 U.S.C. § 841(g) makes it a federal offense to knowingly use the Internet to distribute a “date rape drug” while knowing or having reason to believe that the drug will be used to commit criminal sexual conduct or that the recipient is not an authorized purchaser.

The statute expressly defines “date rape drug” to include:

• GHB;
• controlled-substance analogues of GHB, including GBL and 1,4-butanediol;
• ketamine;
• flunitrazepam; and
• other substances designated by the Attorney General.

A violation of § 841(g) can carry up to 20 years in federal prison.

This provision can be particularly relevant where drugs are allegedly sold through websites, social-media platforms, messaging applications, or other Internet-based channels.

Importantly, simply selling a drug online does not automatically establish a § 841(g) offense. The statute contains specific knowledge requirements concerning criminal sexual conduct or the recipient’s status as an unauthorized purchaser.

The Recent Manhattan GBL Prosecution

The seriousness of federal GBL enforcement in New York City was underscored by a June 2026 prosecution in the Southern District of New York.

Federal prosecutors charged Mark Dygdon and Rodrigo Castro with conspiring to distribute GBL throughout the New York City area. According to the indictment announced by the U.S. Attorney’s Office, the alleged conspiracy operated from approximately August 2023 through June 2026 and involved more than seven U.S. tons of GBL—described by prosecutors as millions of individual doses. The DEA reportedly seized approximately 2.4 tons during the investigation.

Each defendant was charged with one count of conspiracy to distribute GBL, carrying a maximum sentence of 20 years.

The government’s announcement is particularly significant for New York City because it demonstrates that federal prosecutors are willing to devote substantial resources to GBL trafficking occurring within the metropolitan area.

The charges remain allegations, and the defendants are presumed innocent unless and until proven guilty.

Ketamine Is a Schedule III Controlled Substance

Ketamine occupies a different place in the federal drug-scheduling system.

The DEA classifies ketamine as a Schedule III controlled substance. Ketamine has legitimate medical uses, but possession or distribution outside authorized medical channels can violate federal law.

That means a person with a legitimate medical prescription or who possesses ketamine pursuant to authorized medical practice is in a fundamentally different legal position from someone who knowingly possesses or sells illicit ketamine.

Simple Possession of Ketamine

Unauthorized possession of ketamine can be prosecuted under 21 U.S.C. § 844.

For a first simple-possession offense, § 844 generally authorizes:

• up to one year in prison;
• a minimum $1,000 fine; or
• both.

The statutory penalties increase for defendants with prior qualifying drug convictions.

Although one year may appear modest compared with federal trafficking penalties, a federal conviction can have consequences beyond the statutory prison term, including supervised release, immigration consequences for noncitizens, professional consequences, and potential effects on future criminal proceedings.

Distribution of Ketamine

The legal exposure changes substantially when prosecutors allege distribution or possession with intent to distribute.

Under § 841, a violation involving a Schedule III controlled substance generally carries a maximum sentence of 10 years in prison. If death or serious bodily injury results from the use of the substance, the maximum can increase to 15 years. A qualifying prior felony drug conviction can increase the maximum to 20 years, or 30 years where death or serious bodily injury results.

Thus, an allegation that a person sold ketamine at clubs or parties can present a dramatically different federal case from an allegation that the same person merely possessed ketamine for personal use.

Possession With Intent to Distribute

Federal prosecutors do not necessarily need evidence of an actual completed sale to bring a distribution charge.

21 U.S.C. § 841(a) also prohibits possessing a controlled substance with intent to distribute it.

The government’s evidence in such a case might include, depending on the circumstances:

• the quantity of drugs;
• packaging;
• scales;
• large amounts of cash;
• communications concerning sales;
• customer lists;
• multiple types of controlled substances;
• photographs or videos;
• statements by witnesses;
• admissions by the defendant; or
• evidence of prior or subsequent transactions.

Importantly, possession of a relatively large quantity does not automatically establish intent to distribute. The government still bears the burden of proving the charged offense beyond a reasonable doubt.

Federal Drug Conspiracy Charges

Drug investigations frequently result in conspiracy charges in addition to—or instead of—substantive distribution charges.

For controlled substances, 21 U.S.C. § 846 addresses conspiracy to manufacture, distribute, or possess with intent to distribute.

A conspiracy case can reach conduct involving multiple participants, even where a defendant did not personally possess every package of drugs or personally make every alleged sale.

For example, prosecutors could allege that a group of individuals collectively arranged for ketamine or GBL to be obtained, stored, transported, and distributed to customers.

The government may rely on evidence such as text messages, encrypted communications, financial records, surveillance, cooperating witnesses, controlled purchases, package records, and statements made by participants.

Importation Can Create Separate Federal Exposure

GBL and other drugs entering the United States from overseas can create an additional layer of federal criminal liability.

Federal law separately prohibits the unlawful importation of controlled substances, including under 21 U.S.C. §§ 952 and 960.

For a qualifying Schedule I or II substance, § 960 can provide for up to 20 years in prison, with significantly greater penalties when death or serious bodily injury results.

Importation cases can also involve conspiracy charges and allegations concerning false customs declarations, international suppliers, cryptocurrency payments, or commercial shipments.

This issue has recently arisen in GBL investigations outside New York as well. In May 2026, the DEA announced a federal indictment involving an alleged international methamphetamine and GBL trafficking organization. According to the DEA, members of the organization allegedly used sham beauty-product companies in New York and Washington, D.C., to import GBL from South Korea, falsely declaring shipments as cleaning solutions and beauty supplies.

Distribution Resulting in Death or Serious Bodily Injury

One of the most consequential allegations in a federal drug case is that the distribution of a controlled substance caused another person’s death or serious bodily injury.

Federal law provides enhanced penalties for certain § 841 offenses when death or serious bodily injury results from the use of the controlled substance.

For Schedule III substances such as ketamine, § 841 provides a maximum of 15 years where death or serious bodily injury results, compared with a normal maximum of 10 years for the applicable Schedule III offense.

For substances covered by the more serious Schedule I/II provisions, the penalties can be considerably higher, including mandatory minimum terms and potential life imprisonment depending on the drug, quantity, prior convictions, and circumstances.

The causation issues in such cases can be legally complex. The government must prove the elements required by the statute; the mere fact that a person who previously purchased drugs later died does not, by itself, resolve every legal question concerning criminal responsibility.

The Internet Can Make a Drug Case More Serious

Modern nightlife drug transactions frequently occur through digital communications rather than traditional street-corner sales.

Instagram, encrypted messaging applications, websites, cryptocurrency, electronic payment systems, and other digital evidence can therefore become important in a federal investigation.

For GBL and ketamine, the Internet is particularly noteworthy because § 841(g) specifically addresses Internet distribution of substances defined by federal law as “date rape drugs.” That statute can carry a 20-year maximum sentence where its specific requirements are satisfied.

But prosecutors still must prove the statutory elements. The mere use of a phone or Internet-based communication does not automatically transform every drug transaction into a § 841(g) offense.

Federal Charges That May Arise

Depending on the facts, a federal investigation involving GBL, ketamine, or similar drugs could potentially result in charges under several statutes:

The precise statutory penalty depends heavily on the drug’s legal classification, quantity, prior criminal history, alleged conduct, and whether aggravating circumstances such as death or serious bodily injury are alleged.

Federal Versus New York State Charges

A drug arrest in New York City does not necessarily mean that the case will be prosecuted federally.

Most lower-level possession and distribution cases are handled under New York State law, while federal authorities tend to become more involved in cases presenting federal interests such as:

• substantial quantities;
• organized trafficking;
• interstate or international conduct;
• importation;
• darknet or Internet distribution;
• significant financial activity;
• conspiracy;
• firearms;
• large-scale GBL operations; or
• conduct causing death or serious bodily injury.

The same underlying conduct can potentially implicate both federal and New York law, although the ultimate charging decision depends on the circumstances and the decisions of the relevant prosecuting authorities.

What Makes a Federal Club-Drug Case Serious?

For a person accused of possessing or distributing GBL or ketamine, the most important questions often include:

What exactly was the substance? Laboratory analysis can matter enormously. A defendant’s belief about what a substance was does not necessarily determine its legal classification.

How much was involved? Quantity can be relevant both to the statutory penalties and to the government’s theory of intent to distribute.

Was there evidence of sales? Communications, controlled purchases, payment records, and customer evidence can be significant.

Was the defendant actually part of a conspiracy? Federal prosecutors may seek to attribute the conduct of a broader trafficking organization to individual defendants under conspiracy principles.

Did the drugs cross an international border? Importation can create separate federal offenses.

Was the Internet involved? In GBL and ketamine cases, § 841(g) deserves particular attention because Congress expressly included both substances within its statutory definition of “date rape drug.”

Was anyone seriously injured or killed? If so, the statutory exposure can increase dramatically.

Conclusion

GBL and ketamine may be encountered in New York City’s nightlife environment, but their recreational use does not make them legally harmless. GBL presents particularly significant federal issues because of its relationship to GHB, its treatment under federal controlled-substance and chemical regulations, and Congress’s specific treatment of GBL in the federal “date rape drug” statute. Ketamine, meanwhile, is a Schedule III controlled substance, making unauthorized possession and distribution federal crimes.

For a person merely accused of personal possession, the federal penalties may be substantially lower than those applicable to trafficking. But allegations of distribution, possession with intent to distribute, conspiracy, Internet distribution, or importation can expose a defendant to years or even decades in federal prison.

The recent SDNY GBL prosecution is a particularly important reminder that federal authorities are actively pursuing large-scale GBL distribution in New York City—not merely investigating international manufacturers or distributors.

Anyone facing a federal investigation involving GBL, ketamine, or another controlled substance should have counsel examine the chemical identity of the substance, the government’s evidence of knowing possession or distribution, the quantity involved, the defendant’s alleged role, the applicable scheduling provisions, potential conspiracy allegations, and the precise statutory and Guidelines sentencing exposure.
