HALT Fentanyl Act

Summary of Bill S 331
The bill seeks to reclassify certain fentanyl-related substances as Schedule I controlled substances, which are considered to have a high potential for abuse and no accepted medical use. By doing so, the bill aims to make it more difficult for these substances to be manufactured, distributed, and abused.
In addition to the scheduling changes, the bill also includes provisions for increasing penalties for the trafficking and distribution of fentanyl-related substances. This is intended to deter individuals and organizations from engaging in the illegal production and distribution of these dangerous drugs. Overall, the Fentanyl Scheduling Act is a response to the growing public health crisis surrounding fentanyl-related overdoses and deaths. By reclassifying these substances and increasing penalties for their trafficking, the bill aims to combat the spread of fentanyl abuse and prevent further harm to individuals and communities across the country.
Congressional Summary of S 331
Halt All Lethal Trafficking of Fentanyl Act or the HALT Fentanyl Act
This act permanently places fentanyl-related substances as a class into schedule I of the Controlled Substances Act. A schedule I controlled substance is a drug, substance, or chemical that has a high potential for abuse; has no currently accepted medical value; and is subject to regulatory controls and administrative, civil, and criminal penalties under the Controlled Substances Act.
Under the act, offenses involving fentanyl-related substances are triggered by the same quantity thresholds and subject to the same penalties as offenses involving fentanyl analogues (e.g., offenses involving 100 grams or more trigger a 10-year mandatory minimum prison term).
Additionally, the act establishes a new, alternative registration process for certain schedule I research.
The act also makes several other changes to registration requirements for conducting research with controlled substances, including
- permitting a single registration for related research sites in certain circumstances,
- waiving the requirement for a new inspection in certain situations, and
- allowing a registered researcher to perform certain manufacturing activities with small quantities of a substance without obtaining a manufacturing registration.
Finally, the act expresses the sense that Congress agrees with the interpretation of the Controlled Substances Act in United States v. McCray, a 2018 case decided by the U.S. District Court for the Western District of New York. In that case, the court held that butyryl fentanyl, a controlled substance, can be considered an analogue of fentanyl even though, under the Controlled Substances Act, the term controlled substance analogue specifically excludes a controlled substance.

I think this new bill is good cuz it helps stop bad drugs from coming in. It says that it will make it harder for fentanyl to get into our country. I heard that fentanyl is really dangerous and can hurt a lot of people. I hope this bill will make things better for everyone. What do you think about this new law?
