Texas fentanyl laws punish possession, delivery, and manufacture more severely than nearly any other drug offense in the state, and since September 1, 2023, a person who knowingly delivers or manufactures fentanyl that kills someone can be charged with murder and face 5 to 99 years or life in prison. The 88th Legislature created a separate drug classification for fentanyl and related synthetic opioids, raised the penalties at every quantity level, and opened a direct statutory path from a fatal delivery to a murder conviction.
Penalty Group 1-B: The Fentanyl-Specific Classification
Fentanyl, its chemical analogs, and related synthetic opioids sit in their own category under Texas law, called Penalty Group 1-B. Before 2023, these substances were grouped with heroin and cocaine in Penalty Group 1. Carving them out lets the state raise penalties for fentanyl-type compounds without changing the rules for other drugs. Any Texas statute that references Penalty Group 1-B is targeting fentanyl specifically.
Possession Penalties by Weight
Simple possession of any Penalty Group 1-B substance is a felony in Texas, even at trace amounts. Section 481.115 of the Health and Safety Code sets the following tiers, and each weight includes adulterants and dilutants, not just the pure fentanyl content:1State of Texas. Texas Health and Safety Code 481.115 – Offense: Possession of Substance in Penalty Group 1 or 1-B
- Less than 1 gram: state jail felony, 180 days to 2 years in a state jail facility.
- 1 to 4 grams: third-degree felony, 2 to 10 years.
- 4 to 200 grams: second-degree felony, 2 to 20 years.
- 200 to 400 grams: first-degree felony, 5 to 99 years or life.
- 400 grams or more: first-degree felony, 10 to 99 years or life, fine up to $100,000.
Because fentanyl is active in microgram quantities, a handful of counterfeit pills can push the aggregate weight past the one-gram threshold once the filler material is counted. Whether a case is charged as possession or possession with intent to deliver often turns on quantity plus surrounding circumstances like packaging, scales, and cash.
Manufacture and Delivery Penalties
Manufacturing, delivering, or possessing with intent to deliver a Penalty Group 1-B substance falls under Section 481.1123. The tiers are steeper than those for possession, and the higher tiers carry their own sentencing ranges that override the standard felony brackets:2State of Texas. Texas Health and Safety Code 481.1123 – Offense: Manufacture or Delivery of Substance in Penalty Group 1-B
- Less than 1 gram: third-degree felony, 2 to 10 years.
- 1 to 4 grams: second-degree felony, 2 to 20 years.
- 4 to 200 grams: first-degree felony, 10 to 99 years or life, fine up to $20,000.
- 200 to 400 grams: first-degree felony, 15 to 99 years or life, fine up to $200,000.
- 400 grams or more: first-degree felony, 20 to 99 years or life, fine up to $500,000.
All weights again include adulterants and dilutants, so the total weight of the mixture controls the tier.
Murder Charges When a Delivery Causes Death
House Bill 6 added a fourth type of murder to Section 19.02 of the Texas Penal Code. A person commits murder if they knowingly manufacture or deliver a Penalty Group 1-B substance and someone dies after using it, whether the substance was consumed alone or mixed with something else.3State of Texas. Texas Penal Code 19.02 – Murder Prosecutors do not have to prove any intent to kill. They have to prove the defendant knowingly delivered or manufactured the substance and that the victim died from using it.
This is a first-degree felony punishable by 5 to 99 years or life in prison, plus a fine of up to $10,000.4State of Texas. Texas Penal Code 12.32 – First Degree Felony Punishment The statute contains one defense: a person cannot be convicted under this provision if their manufacture or delivery was authorized under the Texas Controlled Substances Act or other state or federal law.3State of Texas. Texas Penal Code 19.02 – Murder That protects licensed pharmacists and medical professionals acting within their authority, not street-level distribution.
Enhancements That Increase the Sentence
Death or Serious Bodily Injury
Section 481.141 raises the punishment for a delivery offense by one degree if a jury finds beyond a reasonable doubt that someone died or suffered serious bodily injury from the substance the defendant manufactured or delivered.5State of Texas. Texas Health and Safety Code 481.141 – Manufacture or Delivery of Controlled Substance Causing Death or Serious Bodily Injury A third-degree felony becomes a second-degree felony; a second-degree becomes a first-degree. The enhanced sentence cannot run concurrently with any other sentence, so it stacks. This enhancement is unavailable if the defendant is being prosecuted for murder under Section 19.02(b)(4) for the same incident; prosecutors have to choose one path.
Drug-Free Zones
Section 481.134 automatically raises a Section 481.1123 offense by one degree if it occurs in a drug-free zone. Drug-free zones include locations within 1,000 feet of a school, college campus, youth center, playground, or residential treatment center, and within 300 feet of a public swimming pool or video arcade.6State of Texas. Texas Health and Safety Code 481.134 – Drug-Free Zones Within 1,000 feet of a school, the minimum prison term increases by five years and the maximum fine doubles. The same enhancement structure applies to delivery involving a minor under 18.
Federal Charges Can Apply Too
Federal prosecutors can bring their own charges for fentanyl distribution in Texas, particularly in cross-border trafficking cases or when the quantities are large. Under 21 U.S.C. ยง 841, distributing a Schedule I or II substance that causes death carries a mandatory minimum of 20 years in federal prison, up to life.7Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A A defendant with a prior felony drug conviction faces a mandatory life sentence, and there is no parole in the federal system.
Under the separate-sovereigns doctrine, double jeopardy does not stop both Texas and the federal government from prosecuting the same conduct. In practice, state and federal prosecutors usually coordinate rather than stacking cases, but a single fentanyl death can create exposure on both sides.
The 911 Overdose Defense Is Narrow
Texas does have a limited defense for someone who calls 911 to report a suspected overdose, enacted in 2021 as the Jessica Sosa Act (HB 1694). It is not blanket immunity. It is an affirmative defense, which means the caller has to prove in court that they qualify. To qualify, the caller must have been the first person to contact 911, stayed at the scene, and cooperated with first responders. The person experiencing the overdose is also covered when someone else calls for them.
The defense does not apply if the caller was already subject to arrest or a search warrant, if they are charged with anything other than drug possession or paraphernalia, if they have a prior drug conviction, or if they have used the defense before. A person who called 911 for an overdose within the past 18 months cannot use it again. Officers can still gather evidence at the scene and charge the caller with other crimes. Anyone who witnesses a possible overdose should still call 911, but treating the law as full immunity would be a serious mistake.
Naloxone Access
Texas pharmacists can dispense naloxone, sold under the brand name Narcan, without an individual prescription through a statewide standing order. Anyone at risk of an opioid overdose, or in a position to help someone experiencing one, can pick it up at a participating pharmacy. Cost varies with insurance, and many community organizations distribute naloxone kits at no charge. Fentanyl can be lethal in quantities invisible to the eye, so carrying naloxone is a practical precaution for anyone who might encounter it.
