Cannabis drug testing describes many drug testing methods for the use of cannabis in medicine, sport, and law.[1]
Cannabis use is easy to detect using urine testing, hair analysis and breath. There are some ways to cheat such a test using synthetic urine or human hair - making blood testing the most effective.[2]
Unlike alcohol, Cannabis testing is time consuming, expensive and cannot give accurate time of consuming and level of intoxication.[3]
The lack of good testing methods and universal intoxication level scale is an issue in the legality of cannabis debate, especially regarding intoxicated driving.[4]
