Confirmed legal status
2C-B
- Legal status
- 2C-B is controlled federally and locally. Federal Schedule I under the Controlled Substances Act, 21 CFR 1308.11(d), DEA code 7392, listed as 4-Bromo-2,5-dimethoxyphenethylamine, and separately controlled under the Guam Uniform Controlled Substances Act, 9 Guam Code Annotated chapter 67.
- Consequences if caught
- The federal Controlled Substances Act applies here. 21 U.S.C. 802(26) defines the term State to mean 'a State of the United States, the District of Columbia, and any commonwealth, territory, or possession of the United States', so the federal schedules and the federal offences reach this territory directly. Federally this is a Schedule I controlled substance, 21 CFR 1308.11(d), DEA code 7392, listed as 4-Bromo-2,5-dimethoxyphenethylamine. Federal simple possession is 21 U.S.C. 844(a). A first offence carries 'a term of imprisonment of not more than 1 year, and shall be fined a minimum of $1,000, or both'. The Guam Uniform Controlled Substances Act, 9 Guam Code Annotated chapter 67 applies as well. Section 67.401.2 of that chapter makes possession unlawful and grades it by substance. Read verbatim: possession of 'any controlled substance except marijuana shall be guilty of a felony of the third degree'; more than one ounce of marijuana 'shall be guilty of a petty misdemeanor'; and one ounce or less 'shall be guilty of a violation and punished by a fine of One Hundred Dollars ($100.00)'. So the same possession is a federal offence capped at one year and a Guam felony of the third degree. The difference is which statute is charged.
- If prescribed / medical
- There is no traveller prescription route. This substance has no accepted medical use in the United States and no prescribable form, so a foreign prescription cannot authorise possession of it.
- Documentation
- Carry any prescribed medicine in its original packaging with the prescription. Bringing a controlled substance into this territory from the mainland United States or from abroad engages federal importation and customs provisions as well as the territorial law, and neither was read here.

- Psilocybin is controlled federally and locally. Federal Schedule I under the Controlled Substances Act, 21 CFR 1308.11(d), DEA code 7437, listed as Psilocybin, and separately controlled under the Guam Uniform Controlled Substances Act, 9 Guam Code Annotated chapter 67.
- Consequences if caught
- The federal Controlled Substances Act applies here. 21 U.S.C. 802(26) defines the term State to mean 'a State of the United States, the District of Columbia, and any commonwealth, territory, or possession of the United States', so the federal schedules and the federal offences reach this territory directly. Federally this is a Schedule I controlled substance, 21 CFR 1308.11(d), DEA code 7437, listed as Psilocybin. Federal simple possession is 21 U.S.C. 844(a). A first offence carries 'a term of imprisonment of not more than 1 year, and shall be fined a minimum of $1,000, or both'. The Guam Uniform Controlled Substances Act, 9 Guam Code Annotated chapter 67 applies as well. Section 67.401.2 of that chapter makes possession unlawful and grades it by substance. Read verbatim: possession of 'any controlled substance except marijuana shall be guilty of a felony of the third degree'; more than one ounce of marijuana 'shall be guilty of a petty misdemeanor'; and one ounce or less 'shall be guilty of a violation and punished by a fine of One Hundred Dollars ($100.00)'. So the same possession is a federal offence capped at one year and a Guam felony of the third degree. The difference is which statute is charged.
- If prescribed / medical
- There is no traveller prescription route. This substance has no accepted medical use in the United States and no prescribable form, so a foreign prescription cannot authorise possession of it.
- Documentation
- Carry any prescribed medicine in its original packaging with the prescription. Bringing a controlled substance into this territory from the mainland United States or from abroad engages federal importation and customs provisions as well as the territorial law, and neither was read here.
