What Do Washington State Marijuana DUI Numbers Tell Us?


I wonder how medical cannabis patients in Washington (and Colorado) handle being “caught” driving at or over the 5ng THC limit.  How does any patient handle having their driver’s license taken away and being unable to drive?  I wouldn’t be able to function without transportation.

As the article below indicates, the 5ng limit is ridiculously low:


While Major League Baseball, and even the U.S. military, allow a limit of 50 ng/ml (nanogram per milliliter) of THC (marijuana’s active ingredient) in urine, the NFL’s new policy sets the limit at 35 ng/ml, up from a threshold of just 15 ng/ml during the last three decades…

Just how much pot a player has to ingest to meet that threshold varies depending on his weight, body fat, and metabolism, but a general rule of thumb is that if you smoked marijuana only once, detectable levels (50 ng/ml) would remain in your system for five to eight days; a near-daily smoker would show levels of 50 ng/ml or more for 33 to 48 days afterward.

If you don't comment, I'll just assume you agree with me
