"Driving laws will be updated, where police can ask for tests for cannabis"

This is a problem that worries me in all the legal markets. Weed can be detected for 30 days or more and, in the U.S. at least, "driving under the influence" is a much more serious crime than possession of marijuana. Essentially, doing these tests and treating cannabis like alcohol in regards to driving despite its vastly different sort of "impairment" creates a system where people who would have been given probation in the past can be sent to prison now. Plus, most evidence and my own experience show that driving while high doesn't cause any significant issue under normal conditions because a user overestimates his or her own intoxication and drives more safely to compensate. With alcohol the opposite is often true. Truth be told, most drugs are probably safer to drive on than alcohol because they are depressants but that is straying into a different rant lol.

This was interesting, I didn't even think about the problem with people admitting use to a border agent until I read it here.
