IN THE WEED: York Region Catholic students talk marijuana with experts

Q: How long after you smoke pot do the effects linger in your system to impact driving?

A: HASHEMINEJAD: It’s a very complicated substance because it does stay in your body and if you’re a regular user, you’re going to experience impairment for a longer period of time.

DE SOUZA: It depends how often you’re using, the amount, the type of cannabis, whether you’re vaping or smoking joints. But you can take a blood or urine test three days after using and it will still show positive results. There should be a significant amount of time between using and driving, and I believe they are saying right now a minimum of four hours.

COLE: Back in the 1930s there was only three per cent THC (the active ingredient that makes you high) in cannabis, and now we’re up to 30 per cent, so there’s a huge difference in potency now on the street. It used to be impairment lasted three hours, but now it can be laced with other things and last much longer

This is both comical and sad.

If you're a regular user you probably have a GREAT Tolerance towards it. If you are a regular user it can stay in your system anywhere from 3 upwards to 6 Months! How do you even drug test that accurately?
What if a regular user smoked a very small amount and drove after 3 hours, would they definitely test positive for taking it recently, yet would they be any more impaired than if they were completely sober?

I LOVE how they word things, "there's a huge difference in potency NOW ON THE STREET"..... as if it is just "Street" bud that has experienced this evolution in potency?
Is this not Natural Selection at it's finest? Why would we knowingly down-breed a strain?

"But now" it can be laced... you mean this was not happening in the 30s? .... Do they even have (NON SKEWED) statistics of this happening now? Who even does that lol.
