Just as there is with the weed laws in Texas, there seems to be a lot of confusion (and misinformation) surrounding driving high and DWI. Is driving high a DWI? Can you get a DWI for weed in Texas? Is driving on your prescription medications illegal?
The short answer is: Yes, you can get a DWI for driving while high in Texas, although there are many complicating factors presented by the presence of illegal drugs and law enforcement’s attitude towards them.
If the cops stop your hot box, you’re likely to face charges for DWI as well as charges for possession of marijuana — and it only gets more complicated from there.

Is driving high the same as drunk driving?
You may have heard the claim that driving high isn’t as dangerous as driving drunk, or that driving while high — depending on the substance in question — doesn’t have the same detrimental impact on your ability to drive a motor vehicle, but these claims are wrong.
Drugs (yes, even weed) alter your reaction time, perception, attention, and coordination in meaningful ways, and can impair you just as much as alcohol — at least in the eyes of the law.
One reason that people may feel more comfortable driving while high is the lack of a legal limit for driving high, but this won’t always work in your favor.
Say you’ve spent a night out with friends and had a few drinks, you get pulled over and breathalyzed, but you blow a .07! You’ve had some drinks, you’ve had a good time, but you’re in the clear. Compare this with a different night out at a friend’s house, one on which you are pulled over after a huge bong rip you took more than two hours ago. You may no longer be very high, but you are very likely to fail the Drug Recognition Expert (DRE) tests administered.
The DRE tests are used to establish intoxication in lieu of having an established legal limit or a way of testing the concentration of drugs in your bloodstream. This means the numbers can’t save you, and it is effectively your word against the arresting officer’s. Because these tests are intended to make it easier to make arrests, and not to accurately measure drug-related intoxication, they were intentionally made to be ridiculously easy to fail.
Is driving high illegal in Texas?
Driving under the influence of any drug is illegal in almost every single state, although a few states have imposed ‘per se’ laws that establish a legal limit of a few nanograms. Just like state weed laws, which are complex and varied, the laws on driving under the influence of weed are becoming a bit less clear — but in Texas, they make it simple.
Driving while high in Texas is legally a DWI. Drug-related DWI charges carry the exact same penalties as any other DWI charges in the Lone Star State, but with the additional caveat that law enforcement officers in Texas are often uniquely tough on drugs.
It might be because even doctors have trouble agreeing on the point at which marijuana begins to impair your judgment, but the zero-tolerance policy seems a bit flawed. It is entirely possible that the DREs will indicate intoxication for people who took an antibiotic, allergy medicine, or other prescription drugs, or even people who aren’t high at all.
If doctors can’t figure out how much weed makes you high, do you think a police officer with a flashlight and pamphlet can? No, they can’t, which is why it is so essential to hire an attorney who knows the law as well as they do the science behind them to defend you.

While many municipalities in Texas are electing not to prosecute for personal amounts of marijuana, if they are arresting you for DWI because you were driving while high, you will likely also face a marijuana possession charge. If you want to defend your freedom, you’ll need to work with a lawyer who knows how to get a possession charge dismissed, as well as how to beat a DWI charge in Texas.
