WARNING: It is dangerous to drive after consuming or using cannabis or any quantity of alcohol. It is dangerous to mix cannabis use and alcohol before driving. The reality is, however, that people in Canada smoke pot in moderation during a night out or when visiting friends and then need to drive home. Sometimes alcohol is consumed as well. One day you will be stopped. If the officer suspects that you have THC or alcohol in your body you may be asked to provide a screening device sample. You may need to prove evidence to contradict the inference that the THC-COOH metabolite found in the lab tests indicates THC in your body at the time of driving.

If you are charged your lawyer and your toxicologist will need to know exactly what you ate and consumed that day (and perhaps that month in the case of THC-COOH or another metabolite) for purposes of proving your blood drug (THC) content at the moment of the alleged offence. This worksheet may help you to provide that information. If already arrested we suggest you also complete the Canadian Cannabis Driving Checklist.

NOTE: We are not suggesting that 1, 2, 3 or 4 cannabis cigarettes or 1, 2, 3, or 4 drinks are safe prior to driving. If you complete this Worksheet after you are arrested, it is not appropriate for you, your companion, and witnesses to make notations on the same Worksheet. Comparison of notes among potential witnesses looks suspicious to the Courts, rather each should prepare a separate Worksheet and not compare notes. Copyright Stephen R.
