Manhattan DUI Drug Lawyers

Under Kansas law, anyone who drives within the state automatically consents to tests of their blood, breath, urine, or other bodily substances to check for the presence of alcohol or drugs. Refusing to take or complete these tests means the tests won’t be administered, but you face severe penalties. A first refusal results in a one-year suspension of driving privileges, with penalties increasing to two years for a second refusal, three years for a third, ten years for a fourth, and permanent revocation for a fifth refusal.

Unlike alcohol tests, which measure blood alcohol concentration (BAC) to establish impairment, drug-related tests only determine if a drug is present in the system. They do not quantify impairment or indicate whether the driver was influenced by the substance at the time of driving. 

For example, marijuana can remain detectable in the blood for days or even weeks after use, making it difficult to prove recent consumption or impairment. This limitation leaves substantial room for interpretation in DUID cases.

Depending on the circumstances of your case, our attorneys may be able to target vulnerabilities within the chemical testing process. We’ll review the chain of custody for the sample, ensuring there was no mishandling that could have compromised its integrity. We can also examine whether the testing equipment was properly calibrated and maintained, as faulty equipment can produce inaccurate results. Procedural errors, such as improper collection or storage methods, can also be grounds for excluding test evidence.

Another avenue for challenge is the interpretation of results. Since these tests lack context regarding your tolerance or impairment level, there’s the potential for arguing that the presence of drugs alone does not confirm impaired driving.
