In Texas, “Poss CS PG 1” is shorthand police and courts use for Possession of a Controlled Substance in Penalty Group 1. It is always a felony. Punishment runs from 180 days in a state jail for less than one gram up to life in prison and a $100,000 fine for 400 grams or more.1State of Texas. Texas Health and Safety Code 481.115 – Offense: Possession of Substance in Penalty Group 1 or 1-B Penalty Group 1 is where Texas puts the drugs it treats most harshly, and a conviction brings consequences that outlast any sentence.
Which Drugs Are in Penalty Group 1
Texas sorts controlled substances into numbered penalty groups rather than following the federal schedules. Penalty Group 1 is defined by Health and Safety Code Section 481.102 and includes the drugs most commonly behind these charges:2State of Texas. Texas Health and Safety Code 481.102 – Penalty Group 1
- Heroin
- Cocaine
- Methamphetamine
- Fentanyl and fentanyl analogs
- Oxycodone (without a valid prescription)
- Hydrocodone (without a valid prescription)
- GHB (gamma-hydroxybutyric acid)
The prescription opioids are worth flagging. The same pill is legal in the medicine cabinet of the person it was prescribed to and a Penalty Group 1 felony in anyone else’s pocket.
What “Possession” Means Here
Texas recognizes two forms of possession. Actual possession is simple: the drugs are on you or in something you are carrying. Constructive possession is broader. You can be charged for drugs found in a car console, a shared apartment, or a storage unit if the state can show you knew the substance was there and had the power and intent to control it.3United States District Court District of Massachusetts. Possession With Intent to Distribute a Controlled Substance
The statute also requires that the possession be “knowing or intentional.”1State of Texas. Texas Health and Safety Code 481.115 – Offense: Possession of Substance in Penalty Group 1 or 1-B Being near drugs is not enough. Constructive possession cases often turn on this element, because proving someone knew about and controlled drugs in a shared space is genuinely hard.
How Weight Decides the Charge
Weight is the single biggest factor in how serious a Poss CS PG 1 charge becomes, and Texas measures it in a way that catches many people off guard. The statute counts the aggregate weight of the mixture, including adulterants and dilutants.1State of Texas. Texas Health and Safety Code 481.115 – Offense: Possession of Substance in Penalty Group 1 or 1-B Every cutting agent and filler counts. A small amount of heroin heavily cut can weigh far more than the active drug alone, and that total weight is what sets the tier.
Penalty Tiers
- Less than 1 gram — state jail felony: 180 days to 2 years in a state jail, up to $10,000 fine.4State of Texas. Texas Penal Code 12.35 – State Jail Felony Punishment
- 1 to less than 4 grams — third-degree felony: 2 to 10 years in prison, up to $10,000 fine.5State of Texas. Texas Penal Code 12.34 – Third Degree Felony Punishment
- 4 to less than 200 grams — second-degree felony: 2 to 20 years in prison, up to $10,000 fine.6State of Texas. Texas Penal Code 12.33 – Second Degree Felony Punishment
- 200 to less than 400 grams — first-degree felony: 5 to 99 years or life, up to $10,000 fine.7State of Texas. Texas Penal Code 12.32 – First Degree Felony Punishment
- 400 grams or more — enhanced first-degree felony: 10 to 99 years or life, up to $100,000 fine.1State of Texas. Texas Health and Safety Code 481.115 – Offense: Possession of Substance in Penalty Group 1 or 1-B
The jump at 400 grams is the sharpest. Minimum prison time doubles from five to ten years, and the fine ceiling grows tenfold.
Drug-Free Zone Enhancements
Health and Safety Code Section 481.134 adds penalty enhancements when the offense happens in or near protected locations such as schools, playgrounds, and youth centers. When the enhancement applies, the minimum punishment is typically bumped to the next higher felony category. A state jail felony case can land in third-degree territory because of where the stop occurred.
Defenses That Come Up Most
Unlawful Search and Seizure
The Fourth Amendment is the most effective angle in a drug possession case. If police found the substance through a search without a valid warrant or a recognized exception, a motion to suppress can keep the evidence out of court. When the drugs are suppressed, the state’s case usually collapses, and nothing about whether you actually had them has to be argued.
Lack of Knowledge or Control
Because the statute requires knowing or intentional possession,1State of Texas. Texas Health and Safety Code 481.115 – Offense: Possession of Substance in Penalty Group 1 or 1-B drugs found in a borrowed car or a shared residence are not automatically yours in the law’s eyes. The state has to tie you to the substance with more than proximity.
Valid Prescription
Section 481.115 does not apply to substances obtained from, or under a valid prescription or order of, a practitioner acting in the course of professional practice.1State of Texas. Texas Health and Safety Code 481.115 – Offense: Possession of Substance in Penalty Group 1 or 1-B For oxycodone or hydrocodone charges, a legitimate prescription in your name is a complete defense. You have to produce the evidence, so pharmacy records matter.
Good Samaritan Defense
Section 481.115(g) gives you a defense at the state jail felony level if you were the first to call for emergency help during a possible overdose, stayed on the scene, and cooperated with medical and police personnel.1State of Texas. Texas Health and Safety Code 481.115 – Offense: Possession of Substance in Penalty Group 1 or 1-B The same protection covers the person who overdosed if someone else called. It does not apply when officers were already arresting you or executing a warrant, and it only reaches the lowest tier. Carrying more than a gram leaves you exposed even if you make the call.
Entrapment
Entrapment requires that law enforcement induced the offense and that you were not predisposed to commit it.8United States Department of Justice Archives. Criminal Resource Manual 645 – Entrapment Elements Courts treat prompt acceptance of a chance to obtain drugs as evidence of predisposition, which makes the defense hard to win.
What a Conviction Costs Beyond the Sentence
Driver’s License
Texas DPS automatically suspends your driver’s license for 90 days after any drug conviction. To reinstate, you have to complete a 15-hour drug education program, pay a $100 reinstatement fee, and carry SR-22 insurance for two years from the conviction date.9Texas Department of Public Safety. Drug or Controlled Substance Offenses If you did not already hold a license, the state will deny you one for 90 days from the conviction date.
Firearms
Every Poss CS PG 1 charge is a felony, and federal law bars anyone convicted of a crime punishable by more than one year of imprisonment from shipping, transporting, or possessing a firearm. Federal rules also restrict firearm possession by anyone who is a current unlawful user of controlled substances, even without a felony conviction.10Federal Register. Revising Definition of Unlawful User of or Addicted to Controlled Substance
Jobs, Housing, Immigration
A felony drug conviction appears on background checks and can block jobs, professional licenses, housing applications, and federal financial aid. Texas does not automatically seal or expunge felony convictions, so the record stays unless post-conviction relief succeeds. For non-citizens, a controlled substance conviction can trigger deportation or bar future immigration benefits. For many people charged with Poss CS PG 1, these downstream effects reshape life more than the sentence does.
