re: Five years later, Colorado sees toll of pot legalization

Spot testing for marijuana intoxication is going to change the world once it is invented. And it will make someone a billionaire.

Right now, just it being in your system could mean you smoked weed 2 weeks ago.

Some companies tobacco test and you could've smoked a cigarette the day before and not get a job. I actually know of a girl in Denver that had that issue when applying for a nursing job and had to take in-home tests to see if she was going to fail for tobacco.
