In Texas, the line between a misdemeanor and a felony drug charge is drawn by two variables: the penalty group the substance falls into and the total weight of the material in your possession. For the most serious controlled substances, even less than one gram is a felony. For others, the threshold is higher. Collin County prosecutors and courts apply these rules consistently, and the consequences of a felony conviction include prison time, fines that can reach $100,000, and a permanent criminal record.

How Texas Drug Law Works: The Penalty Group System

Texas drug possession offenses are governed by Chapter 481 of the Texas Health and Safety Code, commonly known as the Texas Controlled Substances Act. The Act classifies controlled substances into Penalty Groups numbered 1, 1-A, 1-B, 2, 2-A, 3, and 4, plus a separate category for marijuana. The penalty group a substance falls into determines the baseline severity of any possession charge, independent of the amount involved. The amount then determines the specific charge level and the applicable punishment range.

This two-variable system produces a wide range of outcomes. Two people arrested in McKinney on the same day for possessing the same quantity of material can face dramatically different charges depending entirely on which substance was involved. Understanding the classification of the specific substance is the first question in any Texas drug possession case, and it is one that must be answered before the weight of the material becomes legally meaningful.

Penalty Group 1: The Fastest Path to Felony Charges

Penalty Group 1 includes some of the most commonly prosecuted controlled substances in Collin County: cocaine, heroin, methamphetamine, ketamine, oxycodone, and hydrocodone above certain concentrations. Under Texas Health and Safety Code Section 481.115, possession of any Penalty Group 1 substance is a felony offense at every weight level. There is no misdemeanor threshold for these drugs.

The weight thresholds and corresponding charge levels for Penalty Group 1 are as follows. Possession of less than one gram is a state jail felony, punishable by 180 days to two years in a state jail facility and a fine of up to $10,000. One gram to less than four grams is a third-degree felony, carrying two to ten years in prison. Four grams to less than 200 grams is a second-degree felony, with two to twenty years. Two hundred grams to less than 400 grams is a first-degree felony, with five to ninety-nine years. Possession of 400 grams or more is an enhanced first-degree felony with a mandatory minimum of ten years and potential punishment of up to ninety-nine years or life, with a fine up to $100,000.

The Aggregate Weight Rule: Adulterants Count

Texas law calculates weight based on the aggregate weight of the entire substance, including any adulterants and dilutants present. This means that if a substance is mixed with cutting agents, all of that material counts toward the weight calculation. A small quantity of active drug in a larger mixture can push the aggregate weight into a much higher charge tier, which is one of the most consequential and frequently litigated aspects of Texas drug cases.

Penalty Group 1-A: LSD and the Unit-Based System

Penalty Group 1-A consists primarily of LSD. Unlike other penalty groups, possession of Penalty Group 1-A substances is measured by the number of abuse units rather than by weight. Possession of fewer than 20 units is a state jail felony. Twenty to 80 units is a third-degree felony. Eighty to 4,000 units is a second-degree felony. Four thousand or more units is a first-degree felony. Any amount of a Penalty Group 1-A substance is a felony.

Penalty Group 2: MDMA, PCP, and THC Concentrates

Penalty Group 2 includes MDMA (ecstasy), PCP, mescaline, and THC concentrates such as vaping cartridges, wax, and oils extracted from marijuana. The penalty structure for Penalty Group 2 possession begins at the state jail felony level for amounts under one gram and escalates through third-degree, second-degree, and first-degree felonies as quantities increase.

THC concentrates deserve particular attention because they are frequently misunderstood. Traditional marijuana flower is handled under a separate section of the Health and Safety Code with different, and generally less severe, charge levels. However, any cannabis-derived product that contains concentrated THC, including vape pen cartridges and edibles made with cannabis oil, is classified as a Penalty Group 2 substance under Texas law. A Collin County resident who believes they are carrying a small amount of marijuana but is actually in possession of a THC oil cartridge may face felony charges rather than the misdemeanor they expected.

Penalty Groups 3 and 4: When Misdemeanors Still Apply

Penalty Group 3 includes prescription drugs such as Xanax, Valium, Ritalin, and lower-concentration hydrocodone products. Penalty Group 4 includes certain narcotic preparations containing limited quantities of controlled substances mixed with non-narcotic ingredients. These groups are where misdemeanor possession charges remain possible in Texas.

For Penalty Group 3, possession of less than 28 grams is a Class A misdemeanor, carrying up to one year in county jail and a fine of up to $4,000. Possession of 28 grams or more crosses into felony territory at the third-degree level and escalates from there. For Penalty Group 4, possession of less than 28 grams is a Class B misdemeanor. Any amount at or above 28 grams is a felony. The presence of a valid prescription is an affirmative defense that must be presented at trial or in negotiations.

Marijuana: Still a Crime in Collin County

Texas has not legalized marijuana for recreational or medical use. Under Texas Health and Safety Code Section 481.121, possession of two ounces or less of marijuana is a Class B misdemeanor, punishable by up to 180 days in jail and a fine of up to $2,000. Possession of more than two ounces but less than four ounces is a Class A misdemeanor. Four ounces to less than five pounds is a state jail felony. Five pounds to less than fifty pounds is a third-degree felony. The charge escalates further for larger amounts, reaching first-degree felony status at 2,000 pounds or more.

As noted above, the misdemeanor thresholds for marijuana flower do not apply to THC concentrates. This distinction catches many people off guard and produces felony charges in situations where the person believed they were engaged in minor, misdemeanor-level conduct.

Aggravating Factors That Can Increase the Charge

Certain circumstances can increase the severity of a drug possession charge and lead to harsher penalties. Common aggravating factors include:

• Possession in a drug-free zone, such as within 1,000 feet of a school, daycare, or playground, which can elevate the charge by one level.
• Possession of a firearm during the arrest, which may result in enhanced criminal penalties.
• Possession with intent to deliver, a separate offense that carries more severe penalties than simple possession at every weight level.
• Large quantities of controlled substances, which can trigger higher charge levels and sentencing ranges.
• Prior criminal convictions, which may influence charging decisions and potential penalties.

Collin County, with its growing population and active law enforcement presence along the US-75 and the Dallas North Tollway corridor, sees significant drug enforcement activity. Prosecutors in this county are experienced at applying these aggravating factors, and they frequently seek enhanced charges in cases where any additional element is present.
