If you have been looking at a jail record, a bond sheet, or a court docket and saw the words POSS CS PG 1/1-B <1G, here is what it means in plain English: Possession of a Controlled Substance, Penalty Group 1 or 1-B, less than one gram. It is a state jail felony under Texas Health and Safety Code Section 481.115, and it is the single most common felony drug charge filed in Harris County.
Brian Foley and Luis Baez are former Harris County prosecutors who have handled thousands of these cases from both sides. This page breaks the abbreviation down piece by piece, explains the penalties for every weight tier, and covers how these cases actually get resolved in the Houston courts — which, for most first offenders, is not prison.
- POSS — Possession (not delivery or manufacture)
- CS — Controlled Substance
- PG 1/1-B — Penalty Group 1 (cocaine, meth, heroin, oxycodone) or Penalty Group 1-B (fentanyl). The jail code combines them; it does not mean fentanyl was found.
- <1G — Less than one gram, including any cutting agents. Other tiers appear as >=1G<4G, >=4G<200G, and so on.
What Drugs Are in Penalty Group 1 and 1-B?
Texas sorts controlled substances into penalty groups under Chapter 481 of the Health and Safety Code, and the penalty group — not the specific drug — determines the punishment range. Penalty Group 1 is the most serious group and includes cocaine and crack cocaine, methamphetamine, heroin, oxycodone (OxyContin, Percocet), hydrocodone in most forms, hydromorphone, morphine, ketamine, GHB, PCP, and psilocybin mushrooms (which the statute places in Penalty Group 2-A for some forms but Penalty Group 1 for psilocybin itself — the offense report will say which). Penalty Group 1-B was created by the Legislature in 2021 and contains fentanyl, carfentanil, and their analogues, with a harsher punishment ladder that starts at a third-degree felony for under one gram.
Why Does the Charge Say "1/1-B" If I Didn't Have Fentanyl?
This is the question we hear most often. When Penalty Group 1-B was created, Harris County's Justice Information Management System and the systems most Texas counties use did not create a separate charge code for it. Instead they relabeled the existing Penalty Group 1 code as "PG 1/1-B." The result is that every Penalty Group 1 possession case — cocaine, meth, heroin, pills — shows up on the jail roster and docket as POSS CS PG 1/1-B, whether or not fentanyl was involved.
The label on the docket is not evidence. What matters is the substance named in the offense report and confirmed by the lab. If the substance really was fentanyl, the prosecutor should be charging under the separate 1-B punishment ladder (481.1151), and the charge will usually be amended to say so. If it was cocaine or meth, the case proceeds under 481.115 and the penalties below.
Penalties by Weight: <1G, 1G–4G, 4G–200G and Up
The weight tiers are defined by "aggregate weight, including adulterants or dilutants." That means anything mixed into the drug counts, but packaging does not.
| Charge as it appears | Amount | Offense level | Punishment range |
|---|---|---|---|
| POSS CS PG 1/1-B <1G | Less than 1 gram | State Jail Felony | 180 days – 2 years state jail; up to $10,000 fine |
| POSS CS PG 1/1-B >=1G<4G | 1 gram to under 4 grams | Third-Degree Felony | 2 – 10 years prison; up to $10,000 fine |
| POSS CS PG 1/1-B >=4G<200G | 4 grams to under 200 grams | Second-Degree Felony | 2 – 20 years prison; up to $10,000 fine |
| POSS CS PG 1/1-B >=200G<400G | 200 grams to under 400 grams | First-Degree Felony | 5 – 99 years or life; up to $10,000 fine |
| POSS CS PG 1/1-B >=400G | 400 grams or more | Enhanced First-Degree Felony | 10 – 99 years or life; up to $100,000 fine |
If the substance is actually fentanyl (true Penalty Group 1-B), the ladder is steeper: under one gram is a third-degree felony, 1–4 grams is a second-degree felony, 4–200 grams is a first-degree felony, and 200–400 grams carries 10 years to life.
Drug-free zone. Possession within 1,000 feet of a school, youth center, or playground, or on a school bus, raises the offense one level under Section 481.134.
What Actually Happens on a First-Offense <1G Case in Harris County
The punishment range sounds severe, but the realistic outcome for a first offender is very different from the statute:
- Texas Penal Code Section 12.44. A judge may punish a state jail felony as a Class A misdemeanor (up to a year in county jail), and prosecutors can agree to prosecute it as a misdemeanor outright, so the conviction is a misdemeanor rather than a felony. See our page on Section 12.44 reductions.
- Mandatory probation for first offenders. Under Code of Criminal Procedure Article 42A.551, a person convicted of a first state-jail-felony possession under one gram must generally be placed on community supervision rather than sent to state jail, unless they have a prior felony conviction.
- Deferred adjudication. No conviction is entered if probation is completed, and an order of nondisclosure can seal the record afterward.
- Pretrial intervention and drug court. The Harris County District Attorney's Office offers pretrial intervention for many first-time possession cases, and Harris County runs specialty drug courts (STAR and SOBER). Both end in a dismissal, and a dismissed case can be expunged.
- Dismissal. A meaningful share of these cases are dismissed outright for the reasons below.
How POSS CS PG 1/1-B Cases Get Dismissed
The stop and the search. Most under-one-gram cases begin with a traffic stop. If the officer lacked reasonable suspicion for the stop, extended it without cause, or searched without consent, probable cause, or a warrant, the drugs are suppressed and the case ends. We review the body-camera and dash-camera video on every case for exactly this.
Affirmative links. When drugs are found in a car with several passengers or a house with several residents, the State must prove you knowingly possessed them — not just that you were nearby. Texas courts require "affirmative links" (proximity, ownership, statements, fingerprints, and so on), and their absence is a complete defense.
The lab. The charge is filed on the officer's field test and field weight. The Houston Forensic Science Center or the Harris County Institute of Forensic Sciences later tests the substance. Lab results routinely come back as a lower weight (dropping 1G–4G to <1G), a different substance, or no controlled substance at all. Field tests are notoriously unreliable.
Trace amounts and residue. A "usable quantity" is not required for Penalty Group 1, but a residue-only case — a pipe, an empty baggie — is often reduced to possession of drug paraphernalia (a Class C ticket) or dismissed.
Prescription defense. Oxycodone and hydrocodone are Penalty Group 1. A valid prescription is a complete defense, and we obtain pharmacy records early.
What to Do Right Now
If you or a family member was just arrested, the person will be taken to the Harris County Joint Processing Center at 700 N. San Jacinto Street in downtown Houston, will see a magistrate within roughly 24 hours, and will have a bond set. Felony bond in a <1G case is typically modest and can often be reduced to a personal bond. Do not discuss the case with anyone but a lawyer, do not consent to any further searches, and call us at (713) 703-1718 so we can appear at the first setting in the assigned Harris County District Court.
Galveston County cases are handled at the Galveston County Justice Center; you can locate someone through the Galveston County Sheriff's Office inmate search.
