Wow...hippy logic, that was a good one //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
I occasionally smoke and I honestly could care less if people get high, I just like giving people a rough time. People getting high usually doesn't infringe on my rights so I don't care. I do have a problem with people getting high and driving though, thats just downright idiotic. The stoner mentality/lifestyle is annoying too.
I call everyone who smokes, a hippy, because stoners get soooo uptight when you call them a hippy //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
As for deciding where to make the cutoff for impairment I would think some kind of study was performed....who knows.
