Can A Breathalyzer Detect Weed?


Being pulled over because police suspect you are driving under the influence can lead to fear and worry. And if you are asked to blow into a breathalyzer test or perform field sobriety tests, you may be unsure what law enforcement is looking for or how the results of the test will be analyzed. For instance, you may be wondering if they are testing for alcohol or marijuana use.

Currently, breathalyzer tests solely analyze alcohol a person has consumed. While research is being done to develop a THC—the compound that is the active crystalline in cannabis—breathalyzer, there is not one on the market now. The technology is still being created and perfected.

If you are asked to take a breathalyzer test, Texas law enforcement is looking for information regarding your alcohol consumption. Field sobriety tests can be used to determine a range of influences, they can be proof of driving under the influence of alcohol or a controlled substance. Driving while drunk or drugged is dangerous. Additionally, heavy fines and loss of freedom are possible if you are convicted. After an arrest, speak to a Houston DWI lawyer to protect yourself from severe consequences.

Eligibility for Medical Use and Forms of Evidence

It is illegal to use marijuana in the state of Texas, but medical marijuana is accessible in certain situations. Eligible Texas residents can access cannabis with low THC levels through the compassionate use program. Often these individuals are living with seizure disorders, multiple sclerosis, cancer, neurological diseases, or other serious health issues.

That said, whether you are eligible for medical marijuana or not, driving a vehicle while impaired will lead to criminal penalties. If you are arrested for driving under the influence, a Texas prosecutor will provide proof in an effort to secure a conviction. Documentation will vary, but could include arrest reports, the results of field sobriety tests, evidence of paraphernalia in your car or truck, and breathalyzer tests.

Suspicion of Drug and Alcohol Use

It is possible law enforcement has suspected you were under the influence of alcohol and illegal drugs, such as marijuana. For this reason, they may have requested you take a breathalyzer test and perform field sobriety tests as well. Bring the details you have to the attention of a Houston DWI lawyer. If more information is needed, your attorney can gather data and analyze law enforcement reports to strengthen your defense.
