Mr. Speaker, again, I am looking forward to hearing the evidence from scientists, but my understanding is that the saliva-based test for people impaired by cannabis does show recent usage of cannabis. The roadside test is not dealing with fat-soluble concentrations of THC. It is saliva-based so that would show immediate or recent usage.
In terms of medicinal cannabis, if we look at other drugs, whether opioids or other types of drugs that would impair, people still should not get behind the wheel. If they are impaired, they are impaired whether it is prescribed as a medicine or not. It does not matter if it is a drug like an opioid or if it is cannabis; there will be scientific tests to determine whether an individual is impaired by a drug and should not be behind the wheel.
