DWI for Drugs

In Texas, Driving While Intoxicated for Drugs is prosecuted under the same statute as Driving While Intoxicated, or DWI. There is not a different crime because the intoxicating substance was something other than alcohol, despite many people thinking it is a separate crime.

DWI Charges where somebody is seriously injured or killed are felonies. A DWI case if you have twice been convicted of DWI is also a felony offense. Otherwise, DWI for Drugs would be treated as a misdemeanor.

Sometimes a case of Driving While Intoxicated for Drugs also has an alcoholic component. Sometimes, it’s just about drugs. In either case it is important to hire someone who understands the science behind how a lab will look for intoxicants in your body.


If the state took your blood as evidence for a Driving While Intoxicated for Drugs case, they will use a process called gas chromatography. Some people think that just because the state took your blood they will automatically look for any drugs in your system.  This is not actually true.  

The process of preparing a blood sample for analysis requires different chemicals be added depending on which substance they are testing for.  The preparation for cocaine requires a different internal standard and a different column in the gas chromatograph.  What does this mean for you?  Well the more complicated the process, the more opportunities for the government to make a mistake.

Many complicated issues can arise when the government is trying to use your blood against you in a Driving While Intoxicated for Drugs case. Did the lab leave your blood out for too long with no refrigeration? Did they use expired chemicals?  Did they calibrate the machine?  When did they calibrate the machine? Did they prepare the sample the same way they are supposed to?  Did they switch your vial with another person’s?

But, imagine if your lawyer doesn't understand the process.   How is he ever going to exploit those possible mistakes for you?  If he or she doesn't understand these processes, how will they convince a jury that you are not guilty and the lab made a mistake?

RC has attended several college-level courses specific to gas chromatography. If your case involves gas chromatography, or blood measurements of any kind, you should read about a Lawyer-Scientist.

If you are charged with Driving While Intoxicated for Drugs, there can also be a separate charge for possession of drugs.  For the vast majority of drugs this would be a felony level offense.  The Law Office of RC Pate has had experience in handling these cases as well.  


In the days immediately following a DWI Arrest you should do these things.  It is important to get your car back, get some rest, then get a lawyer. 


There could also be a Driver’s License Suspension if you are charged with Driving While Intoxicated for Drugs.  This suspension can only be avoided if you request a hearing within 15 days from the day you were arrested. My advice to you is to hire a lawyer to handle requesting that hearing.
