The prosecution of DUI cases based upon drug impairment (CVC 23152(a)) is more complex for prosecutors than alcohol-related DUI’s. The main reason for this is because “impairment” can be more difficult to prove, which makes these cases more difficult to prosecute.

Over the years, most DUI studies have focused on the effects of alcohol on driving ability and the body. Unlike alcohol, the impairment due to certain drugs is much less defined since there is no legal limit to the amount of certain drugs you can have in your blood stream.

In addition, there are such a large variety of “drugs” – illegal drugs; prescription drugs; over-the-counter drugs, etc. – that it can be difficult for prosecutors to prove if the substance found in your blood stream caused any impairment. Prosecutors usually rely on circumstantial evidence – evidence of your driving pattern, appearance, and performance during field sobriety tests – to prove that you were impaired.

Combination of Drugs and Alcohol

If your case involves the combination of alcohol and drugs, the investigation and scientific analysis is even more complex. The prosecutor must prove beyond a reasonable doubt that the combination of alcohol and drugs found in your blood stream substantially impaired your ability to safely operate a vehicle. Since each combination of drugs and/or alcohol has a different effect on a person’s body, it will be difficult for the prosecutor to prove that your specific combination made you impaired to the level that it would be unsafe for you to operate a vehicle.

Level of Impairment

When dealing with drug impairment, a determination that you are unable to safely operate the vehicle will fluctuate depending on the dose and how fast the substance is eliminated from your blood stream. Of course, these factors differ from person to person. This is also true for drunk driving cases based upon alcohol impairment.
The particular facts and circumstances of each suspect’s case will drastically impact how alcohol moves through and impacts the body, both physically and mentally.
