Intoxicating Substances

While driving under the influence of alcohol is by far the most common reason for motorists to be charged with DWI in Texas, it is in fact possible to be accused of driving while intoxicated even if the defendant had absolutely no alcohol in his or her system at the time of the arrest.

Whatever the cause of a person’s impairment, it is important for people to be aware of the fact that they may be accused of DWI for more than just alcohol consumption. As such, telling an officer that you are not drunk, but rather, a little fuzzy because you are on medication will not prevent you from receiving a DWI, and may actually work against you.

What Exactly is Intoxication?

Impairment due to the introduction of any substance to the body can count as intoxication. Texas Penal Code sec 49.01 states that “Intoxicated” means that a person’s normal physical or mental capabilities are impaired after introducing any of the following to their body:

  • Alcohol
  • Controlled substances
  • An intoxicating drug (legal or illegal)
  • Any other substance that causes impairment

The last item on this list indicates how broad the interpretation of intoxication can truly be.
