Dr Leo Schep

• Analysing hair, urine and blood tests.
• You can usually tell if someone is using medical marujiana or if there is recreational use based on the results.
• Timelines for how long tests can work - urine, blood vs hair follicle tests AND also depends on the type of the drug (this is a must listen to).
• "What implication does that have on the impairment of the individual?"
• If someone uses a drug once does it show up in the test? May be a small blip on the test. You cannot correlate back to a dose, but some studies can bracket results in low, medium, high.
• Leo says you can get an estimate of drug use in a test. CDT testing (alcohol use).
• Benefits and negatives of various tests - hair, blood, urine. Understanding what each test offers.
• What should lawyers include in the instructions to a toxicologist. "We can form a conclusion with caveats" from drug testing.
• What killed Alexander The Great? (Interesting discussion).
• Illustrating the importance of cross disciplinary discussions.
