As I referenced in my speech, Mr. Speaker, there is no legal limit. I referenced the situation with THC and cannabis.
Admittedly, the substance in an individual's system can exist for up to four weeks, but there are also physical signs and physical conditions when the individual is pulled over on the side of the road and given the field test. He is then taken to the station and receives the DRE analysis, the expert analysis, which takes roughly three-quarters of an hour. The combination of all of these will conclude whether in fact there is impairment of that individual at that specific time. The existence of THC alone will not do so.
