"Regular smokers were used because previous tests in America using first-timers resulted in the volunteers falling over and feeling ill."

According to the study you cited, "although the cannabis affected reaction time in regular users, its effects appear to be substantially less dangerous than fatigue or drinking."

It does NOT say that marijuana is not a factor.

[Charles H. (The_r0nin)]

From your link to http://www.newscientist.com/article.ns?id=dn2063:
In the study, cannabis significantly affected only one criterion, known as tracking ability. Volunteers found it more difficult to hold a constant speed and follow the middle of the road accurately while driving around a figure-of-eight loop. The TRL researchers point out in their draft report that this test requires drivers to hold their concentration for a short time, a task which is particularly badly affected by the intoxicating effects of cannabis.

So the inability to drive in a straight line and stay on your side of the road is no problem, eh? You know what the defining characteristic of a zealot is, right? The ability to reframe any statement, no matter how damning, so that it seems to support his premise. Anyone with an ounce of sense reading the above paragraph would have to admit that driving while high is incredibly dangerous. But the weed-zealots try to minimize the dangers by comparing it to driving drunk (clever, but disgustingly dishonest). Driving while impared is dangerous, whether on weed or on booze. Neither should be tolerated...
