What Are Controlled Substances Under Texas Law?

You often hear the term “controlled substances” used when referring to illegal drugs. But what, exactly, are controlled substances under Texas law?

Free Consultation

Also known as CDS, or controlled dangerous substances, these drugs include heroin, cocaine, meth, and marijuana, as well as the compounds used to manufacture narcotics, synthetic steroids, depressants, and stimulants. These are substances with high potential for abuse which may lead to severe psychological or physical dependence.

Alcohol and tobacco, two of the most dangerous and harmful drugs, are not included among the controlled substances in Texas. Though they too have killed millions, they are legal drugs.

Texas laws on illegal drugs can be extremely strict, as provided by the Texas Penal Code and the Texas Controlled Substances Act, which was enacted in 1973. Punishments can include steep fines, jail time, a six-month suspension of your driver’s license, and mandatory drug addiction treatment. Drug crime convictions can also lead to negative impacts on your job and employment prospects, the places where you’re able to live, and even your education opportunities.

As for drug crime charges in Texas, these can vary widely depending on the circumstances. For example, possession of a controlled substance in Texas can be a felony or misdemeanor depending on the type of drug, the amount of the drug, and whether or not there was an intention to sell (“traffick” in) the drug.

Overall, criminal charges for drug crimes in Texas can range from a class C misdemeanor (the least severe) to a first degree felony (the most severe).

What is Possession of a Controlled Substance?

In legal terms, being charged with possession of a controlled substance in Texas means that a law officer has probable cause to believe you had “care, custody or control” over a substance which is deemed illegal under the Texas Controlled Substances Act.

Such substances are divided by Texas drug laws into four groups of drugs. These are known as Penalty Groups 1, 2, 4 and 4. Marijuana is in its own separate category, with its own penalties.

Penalty Group 1

This group includes cocaine, mescaline, ketamine, methamphetamine (meth, crystal meth), opioids ( painkillers such as hydrocodone, oxycodone, and codeine), opium derivatives or opiates (including heroin), as well as psilocybin and comparable hallucinogens. Penalty Group 1-A includes LSD (lysergic acid diethylamide). Punishments for Penalty Group 1 can start at two years in jail and a $10,000 fine, but can extend to a $250,000 fine and a life sentence in prison for possessing 400 grams or more.

Penalty Group 2

This group includes hashish and other cannabinols derived from cannabis or marijuana, as well as PCP and Ecstasy (MDMA). Penalties for Group 2 start at two years in jail for possessing under one gram and increase to a $50,000 fine and a life sentence in prison for having 400 or more grams.

Penalty Group 3

This group includes opiates and opioids not listed by Penalty Group 1, along with anabolic steroids, benzodiazepines, and sedatives such as Valium, methylphenidate (also known as Ritalin), and prescription drugs which have a depressant or stimulant effect and the potential for addictive abuse. Penalties for possessing drugs in this group start at a year in jail and a fine of up to $4,000, but can increase to a fine of as much as $10,000 and a 20-year prison sentence for having 200 or more grams.

Penalty Group 4

This group includes opiates and opioids unlisted by Penalty Group 1 or 3, as well as chemical compounds and some prescription medications with a potential for abuse. Penalties for drugs in this group are comparable to those for the drugs in Group 3.

Texas Drug Crime Punishments Can Be Severe


Texas drug laws provide penalties and punishments based on the circumstances of drug possession, and these can be severe.

For instance, if you manufacture or deliver (sell) a controlled substance, you can face punishments of 180 days to two years in jail and a fine of up to $10,000 — but those are just the minimum punishments. Maximum punishments for manufacturing or delivering a controlled substance in Texas include fines of up to $250,000 and prison time ranging from 15 to 99 years, with a life sentence also possible.

Penalties and punishments increase if the drug is possessed in what’s considered a “drug-free zone.” Such zones in Texas include being within 1,000 feet of a private or public elementary school, secondary school or daycare center.

Penalties aren’t as severe if you’re arrested for possessing a controlled substance only for your own personal use as opposed to possession with the intention to distribute.

Federal Controlled Substances Laws

You may also be interested to know about federal laws pertaining to controlled substances. Enacted in 1971, the Controlled Substances Act includes five “schedules,” or classifications of controlled substances.

The most severe category is Schedule 1. It includes such drugs as heroin, LSD, MDMA (Ecstasy), psilocybin, psilocin and marijuana. Drugs included in this category are said to have a high potential for abuse, lack currently accepted medical treatment value, and lack an accepted safety use. This category is similar to Texas’ Penalty Group 1.

Even non-violent, first-time offenders convicted of trafficking (selling) Schedule 1 drugs can face a life sentence in prison. Also, be advised that across America, arrests for heroin and meth distribution are rising.

He doesn't give up, no matter what you're up against
Client's child sex abuse case was dismissed

" This man saved my life from false imprisonment. Neal's belief in 'liberty and justice for all' as laid out in the Constitution of the United States, and especially as that principle relates to constitutional rights regarding the receipt of a fair trial, coupled with his refusal to quit fighting, are attributes of a noble spirit and a man of high character. When I interviewed Neal to defend me against very serious false accusations and criminal charges that followed, his candor about what I was up against and his real interest in my general welfare made choosing him to defend me a 'no brainer.' Hiring Neal after hearing Dick DeGuerin say 'Neal is a real fighter' was the best decision I could have made and this was after interviewing a number of attorneys. He cares about people, truth, and justice; an attorney who will not give up; a man who will defend the rights of anyone accused of a crime with every fiber of his being to ensure fairness and the protection of our legal rights."
