Alcohol, medications and illicit drugs are widely used and can affect judgement, inhibitions and memory. Often crimes occur where the complainant, defendant or witnesses have consumed drugs or alcohol. We can provide independent analysis of blood or urine samples for the presence and levels of alcohol and drugs. Estimating intoxication at the time of an crime or injury, rather than at the time of the blood test would provide a more accurate insight into the relationship between intoxication and the case being investigated. Our experts can also consider the effects of exposure to drugs, medications, solvents and chemicals.
