If we're doing anecdotes I'm sure there are lots of drunk drivers with spotless records.

I understand that you're taking issue with the idea of always being impaired, but the article indicates that there's a pretty clear association between having ingested THC and being in a car crash.

Don't we need baseline levels to see the association?

You think 40% of the population is using? That seems like a pretty big reach to me.

There’s also an association with having drank water and been in a car crash. This on its own can’t reasonably inform any opinions, more context is required.

This is blatantly intellectually dishonest. If 100% of people drink water then it’s not surprising when 100% of people in car crashes have been drinking water.

If less than 40% of the population has impairment levels of THC at any given time but 40% of deceased car crash drivers have impairment levels of THC in their blood, you can’t pretend that THC use is equivalent to drinking water.

The mental gymnastics being done in this thread to try to ignore this study are fascinating.

Enough with the pedantry please:

"Driving under the influence of cannabis was associated with a significantly increased risk of motor vehicle collisions compared with unimpaired driving (odds ratio 1.92 (95% confidence interval 1.35 to 2.73); P=0.0003); we noted heterogeneity among the individual study effects (I2=81)".
