re: Spinoff: Washington Sees Fatal Road Crashes Involving Marijuana Double

I just read the article and I'm curious what "recently" means. They keep saying drivers who "recently" used marijuana but don't define the time frame. Since THC stays in your system for a few weeks, I'm wondering if these people just had THC in their system or if they were actually high while driving.

Valid questions. I'm not even sure if there's a test that can determine if you just smoked a bowl or still have it in your system from a few days ago.

I just saw this link while researching numbers for the Astronaut drunk driving thread and thought this article would spark some good discussion.

I suppose as states adopt legalization there needs to be scientific studies on the effects of driving while under the influence of marijuana. How much is "too much"? How long should one wait to drive after consuming it? What we don't need is knee jerk reactions on either side who either (a) claim there is no risk of driving while under the influence of marijuana or (b) try to use studies such as this one to argue against legalization.

It's a paper from a month ago or so. Only the newspaper/reporting entity uses the term "recently used". I believe WAPO was the first to report it as such. The source material never uses that term, and their conclusions are complete rational and in line with what we already know. That there is no sufficient test to measure MJ toxicity in real time, and the data they have compiled is unreliable as a result.

The traffic Safety Council's paper is actually well done. The reporting of it, on the other hand...
