Attorneys for THC-Related DWI Charges in Houston, Texas

Defending Against Cannabis-Related DWI Charges in Houston,TX

If you're facing a DWI in Texas, you're undoubtedly worried about what will happen next and the charges you might face. If the police allege that you were intoxicated with cannabis or a derivative like THC, Delta-8, or CBD, you may be in a grey area concerning the law. While many states have embraced the legality of pot, Texas has not. In fact, Texas has some of the harshest marijuana laws in the country.

THC is explicitly illegal in Texas. You can face penalties for possession, production, and selling THC, even though possession of THC is now legal in many states in the U.S. But along with the legality of THC and some THC products, manufacturers have gotten creative with THC to avoid laws banning the psychoactive substance in the remaining states. New THC compounds like Delta-8 and Delta-10 are popping up in stores all over Texas, along with CBD products. These THC and CBD products aren't illegal in Texas—yet—even though they are chemically similar to Delta-9 THC, the chemical in pot that makes you high.

But it's important to remember that even if substances like Delta-8 or CBD are legal—or at least aren't illegal—if they impair you to the point where the police believe you are intoxicated, you can still face a DWI. Regardless of whether you're facing a DWI or a DWI and drug charges, you need a skilled Texas attorney who has experience in both DWI defense and criminal law.

Drug DWI in Texas

If you're driving under the influence of THC, Delta-8, or CBD, you could still face DWI charges. In Texas, driving while intoxicated doesn't have to involve alcohol. You may also face arrest if you are "intoxicated" because of drugs, alcohol, or a combination of the two.

1. Definition of DWI in Texas

Texas law defines driving while intoxicated as:

  • Having a BAC of .08% or higher, or .04% or higher if you have a commercial driver's license, or
  • No longer having the normal use of your physical or mental faculties.

Texas Penal Code § 49.01 specifically defines "intoxication" as:

"[N]ot having the normal use of mental or physical faculties by reason of the introduction of alcohol, a controlled substance, a drug, a dangerous drug, a combination of two or more of those substances, or any other substance into the body; or having an alcohol concentration of 0.08 or more."

2. Testing for Controlled Substances

Although Texas law defines one objective standard for a DWI, a BAC of .08%, this standard doesn't apply to a drug DWI. There is no single standardized test to measure the type or amount of drug in an individual's system. As a result, Texas law doesn't have an objective standard for the amount of drug that should be a DWI. Moreover, there are no specific scientific standards agreed upon by experts as to what level or amount of a drug will result in intoxication. Because of this, some prosecutors will try to use any positive drug test as evidence of driving while intoxicated. Beware of law enforcement officials who try to railroad you with a positive drug test. A drug test is not a BAC test.

3. The 12 Drug Recognition Protocol Steps

Because there is no drug equivalent of a BAC test, law enforcement officers developed a series of 12 tests and observations to help identify drug intoxication. The series of tests is called the Drug Recognition Expert Protocol (DRE). The National Highway Safety Administration adopted DRE protocols in the 1980s, and states across the U.S. followed. There is a certification available for police officers as well. But the protocol process is by no means infallible. The DRE protocol steps can be quite unreliable. In some states, the courts will not allow police officers to deliver "expert" opinions based on the DRE protocol steps. The 12 steps include:

  • BAC Breath Test: First, the investigating officer will take your BAC using a breath test. If the arresting officer doesn't believe this explains your behavior, they can request a DRE evaluation.
  • Arresting Officer Interview: When the DRE officer arrives, they will interview the police officer on the scene and discuss your arrest, behavior, and any symptoms of intoxication.
  • First Pulse and Preliminary Exam: The DRE officer will also take your pulse and do an initial examination. The DRE officer will look at your attitude, behavior, speech, coordination, and demeanor.
  • Eye Exam: The DRE officer will look at your eyes and watch for "ocular convergence" using the Horizontal Gaze Nystagmus (HGN) and the Vertical Gaze Nystagmus (VGN) tests.
  • Divided Attention Psychophysical Tests: The DRE officer will then ask you to submit to several field sobriety tests to see if your motor coordination is compromised when you try to complete multiple tasks. The field sobriety tests you take may include the Walk and Turn, the Romberg Balance, the One Leg Stand, and the Finger to Nose tests.
  • Second Pulse and Vital Signs: The DRE officer will take your pulse and vital signs again after your field sobriety tests.
  • Dark Room Exam: Next, the DRE officer will watch your pupils under several lighting conditions with a pupilometer. The officer is looking for constricted, dilated, or normal pupils.
  • Muscle Tone Exam: The DRE officer will then observe your muscle tone, watching to see if your muscles are rigid and constricted or flaccid and loose.
  • Third Pulse and Check for Injection Sites: Next, the DRE officer will take your pulse once again and examine you for evidence of recent drug use by looking for injection sites on your skin.
  • Taking Your Statement and Other Observations: The DRE officer should read your Miranda rights before asking you about any drug use.
  • Analysis and Opinions of the DRE: Next, the examiner will review all of their observations and your exams and decide whether you are intoxicated and what substances you may have taken.
  • Toxicological Exam: Finally, the DRE officer will ask you to take voluntary blood, urine, or saliva tests to check for drug use.

It's important to remember that a DRE analysis isn't an objective process. Most of the steps involve the appearance of objectivity but rely on the examiner's subjective interpretations. DRE officers are not physicians, and they can easily misinterpret behavior and physical responses related to medical conditions or normal behavior as drug-related. That's why it's essential that you hire an experienced drug DWI attorney as soon as possible.

Drug DWI Penalties in Texas

Penalties for drug DWIs can vary based on any prior convictions, the substances allegedly involved, and the circumstances of your stop, including whether you're involved in an accident or other aggravating circumstances like an accident, a serious injury, or death.

  1. First DWI: In Texas, a first DWI is a Class B misdemeanor carrying penalties of up to 180 days in jail, a fine of up to $2,000, up to one year of a license suspension, and an additional mandatory administrative fine of $3,000.
  2. Second DWI: A second DWI is a Class A misdemeanor, carrying penalties of up to one year in jail, up to $4,000 in fines, a suspended license of up to two years, and an additional mandatory administrative fine of $4,500 for a second offense in 36 months or $6,000 for a BAC over .15%.
  3. Third or Subsequent DWI: In Texas, a third DWI is a third-degree felony, carrying penalties of up to ten years in prison and up to a $10,000 fine. A fourth DWI may be a second-degree felony with penalties of twenty years in prison, a $10,000 fine, a two-year license suspension, and additional mandatory administrative fines.

You can also face more severe penalties for a DWI that involves an accident, injury, or death of someone else. An arrest for a DWI with a child passenger under 15 is also a state jail felony.

Searches Incident to an Arrest

When the police pull you over and suspect that you are under the influence of drugs, they can't just pull you out of the car and search you and your car. The police need a search warrant to search you, with a few exceptions, including:

  • The police have probable cause to believe you have incriminating evidence,
  • You consent to the search,
  • There's a safety reason for the search, like a gun within your reach, or
  • A search incident to your arrest.

You don't have to consent to a search of your person or car. There's no need to make it easier for the police. If the police arrest you, they will search your car to take "inventory." However, if they find anything illegal like drugs, you may face additional charges.

Cannabis Products in Texas

1. THC

THC or tetrahydrocannabinol is also known as Delta-9 THC. It is extracted from cannabis, which comes from the cannabis Sativa plant. When people refer to "THC," they're typically referring to Delta-9 THC, which is the component of cannabis that makes you high. People may smoke the cannabis plant or use THC oils, edibles, gummies, or supplements to get high. However, possession of THC in Texas is illegal. Possession of marijuana in Texas has its own penalty group. But possession of THC and THC products is punished more severely than marijuana possession. Texas places THC edibles like gummies in a different category from marijuana, making possessing THC edibles in Texas a felony.

2. Delta 8 THC

Necessity is often the mother of invention, and THC manufacturers have gotten creative in recent years. By manufacturing chemically similar products to Delta-9 THC, like Delta-8, Delta-10, and CBD, they've managed to skirt Texas state law. Delta-8 is a cannabis compound that's become widely popular because it is similar to Delta-9 THC, the main compound in cannabis, or pot, that gets people high. It's extracted from cannabis or hemp and falls in a grey legal area. Unlike Delta-9 THC, which is illegal in Texas, Delta-8 THC isn't explicitly illegal in many states.

Delta-8 is an isomer of Delta-9 THC, and it produces similar, albeit milder, euphoric feelings to what Delta-9 THC creates. The only chemical difference between the two compounds is the location of a double bond between two carbons. Some states have already made Delta-8 illegal, but Texas hasn't yet. However, that doesn't mean the law won't change as legislators catch up with THC manufacturers. Moreover, you should be wary of driving while using any substance that produces a high. If the police pull you over while impaired, you can face DWI charges while using drugs, whether they are legal or not. Even prescription medication can lead to a DWI charge in Texas if you are "intoxicated," as defined by the law.

3. CBD Products

CBD is another product popping up in stores all over Texas. CBD is extracted from either hemp or cannabis and is often sold as gummies, oils, supplements, and extracts. In June 2019, Governor Greg Abbott signed a law making hemp legal in Texas as long as it contains 0.3% or less THC. The law, which went into effect in September 2019, excludes hemp from the definition of marijuana under Texas law. The new Texas law followed on the heels of a federal bill in 2014 that removed Hemp from Schedule 1 of the Controlled Substances Act (CSA) and then in 2018 removed it from the CSA entirely. However, if CBD contains more than 0.3% THC, Texas law still classifies it as marijuana. If you purchase a mislabeled product, you could be guilty of possessing marijuana without even knowing it.

THC and Drug Possession in Texas

If you're stopped for a DWI, and the police search your car or "incident to an arrest" and you have THC, marijuana, or CBD with more than 0.3% THC in the car, you could face charges for drug possession. The penalties for drug possession can be steep depending on the amount in your possession, the classification of the drug, and whether it's marijuana or THC products.

In Texas, anyone who "knowingly or intentionally" possesses a penalty group substance without a valid prescription can face steep penalties for drug possession. The Texas Controlled Substances Act has six penalty groups for illegal drugs, with Group 1 as the most serious and Group 4 as the least.

THC oils and edibles other than marijuana fall under Penalty Group 2 in Texas. Group 2 also includes drugs like PCP, many amphetamines, and ecstasy. Penalty Group 2 includes many popular THC products like oils used in vape cartridges, edibles, and gummies. Possession of vaping THC cartridges and THC edibles in Texas can be a state jail felony charge. CBD products containing more than 0.3% of THC fall under Penalty Group 2 as well. Penalties include:

  • For less than one gram, the penalties include up to a $10,000 fine and 180 days to two years in prison and is a state jail felony.
  • For one to four grams, penalties include fines of up to $10,000 and two to ten years in prison and is a third-degree felony.
  • Possession of four to 400 grams is a second-degree felony, with fines of up to $10,000 and two to twenty years in prison.
  • Possession of four hundred grams or more is a first-degree felony with fines of up to $50,000 and five to 99 years in prison.

In contrast, possession of under 2 ounces of marijuana in Texas is a Class B misdemeanor, with penalties of up to 180 days in jail and a $2,000 fine. Possessing two to four ounces of marijuana is a Class A misdemeanor, and you can face up to one year in jail and a $4,000 fine. Of course, penalties increase for larger amounts of marijuana. Possession of four ounces to five pounds is a state jail felony with penalties of 180 days to two years in jail and up to a $10,000 fine.

Controlled Substance DWI Defenses

It's important to remember that testing positive for a controlled substance is not the same as being under the influence of a controlled substance. Many controlled substances remain in the blood for quite some time, even after their effect on the body wears off. As a result, much of the evidence used for a controlled substance DWI conviction can be subjective. An experienced DWI attorney can often develop a well-rounded defense on your behalf by attacking reasonable suspicion for the initial stop, probable cause for your arrest or drug testing, failure to give you your Miranda warning, and attacking the DRE testing protocols and lab tests. A Texas attorney well-versed in drug DWI charges can help you develop the best possible defense for your case.
