The drug test is not for a specific level, but any level. Does that create a problem? If a person consumes a drug, he or she can test positive up to a week later. Obviously, the person’s driving would not be affected at that stage. The test is just detecting the legacy of something that happened well in the past. Is discretion applied? Are there issues? Does the test involve any measurement or estimate of how long before being detected the person had taken the drug?
