That’s not the relevant bit. A blood test detects recent use of THC.
Which other, less invasive methods cannot. Like alcohol, impairment is
highly individual and so we set a threshold.
- squigz 10mo agoIt is not a reliable indicator of recent use though, since it can also indicate past use. I agree we need to set a threshold for impairment. I just want that to be measured reliably so that people who had a brownie last weekend aren't getting in trouble.
- reactordev 10mo agoTHC leaves the bloodstream within 24 hours just to be clear. I know this is a giant hairball and the downvotes and passionate discussion is why I said what I said but in the end, until we have a breathalyzer for THC, it is what it is.
- nobodyandproud 10mo agoDriving isn’t a right. No matter how steeped the US is in car culture, it’s important not to lose sight of this. Now blood tests show a 12-24 hour window of usage. Much tighter than the 2 to 30 days of other tests. In terms of window of time, that’s essentially good-enough. Of course anyone who consumes cannabis has a strong desire for a tighter and more accurate test, but you’re really fighting against growing masses of irresponsible users. If the problem is truly wide-spread like alcohol was (and still is), it’s just a matter of time before states or feds push for a good-enough (for the rest of us) solution.
