When a person is suspected of driving under the influence of alcohol, the police can usually use a breath test machine to determine the person’s BAC fairly quickly and in the police station. When a person is suspected of driving under the influence of cannabis or other drugs, the testing process is more complicated. Police usually need to send samples out to a crime lab that can test for the presence of drugs. New reports are now suggesting that testing errors in a Chicago lab may have led to an uncertain number of false positive results for cannabis. This means that drivers who were convicted of a drug DUI after testing positive for cannabis may be able to challenge their convictions based on new evidence. If you were convicted of a DUI based on a drug test carried out by the University of Illinois Chicago Analytical Forensic Testing Laboratory, you should speak to a Will County, IL DUI attorney as soon as possible.
