Address at International Association of Chiefs of Police Convention, Using Oral Fluid in DUID
Enforcement Cases (July 30, 2014) (PowerPoint on file with American Criminal Law Review).
But Kleiman argues that many of the people who complained about the DUID
standard during the I-502 campaign were medical marijuana suppliers who were mainly interested in defending their financial interests.
Norton arrived with a THC level of 16 nanograms, more than three times Colorado's new DUID
cutoff, but nevertheless completed a driving course satisfactorily, according to the instructor who accompanied her with his foot hovering over a second brake and his hand ready to take the wheel.
With the short detection window for THC, breath collection may offer an alternative matrix to oral fluid for DUID
and "for cause" workplace drug testing when testing occurs <2 h after smoking.
But in February, Colorado's House Judiciary Committee unanimously approved a bill that would allow DUID
convictions based on nothing more than a five-nanogram reading.
Many states and countries have per se or "zero tolerance" legislation for DUID
with analytical cutoffs.
These combinations provided a shorter window of detection (1-6 h) that might be appropriate for DUID
, because this time frame is similar to the acute intoxication impairment window.
cases, it is important to identify recent cannabis exposure of <8-12 h, especially as cannabis was often the most prevalent drug identified in injured drivers (39).
No studies, to our knowledge, have directly examined whole-blood cannabinoid pharmacokinetics in humans following cannabis smoking, although this matrix is often used for forensic and DUID
Establishing reliable evidence of recent cannabis exposure is important for drug treatment, workplace, DUID
, and accident investigations.
Legislators and police officers want to rapidly perform DUID
testing at the roadside, eliminating transport to hospitals or police stations.
As OF testing gains acceptance in DUID
, workplace, and clinical monitoring scenarios, validation of robust, sensitive, and cost-effective screening assays will allow detection of illicit drug use while reducing confirmatory demands on personnel and instrumentation.
