Just following up on my previous post; now that I’m not at the whims of a dial-up modem, I’ve got a more secure Internet connection and can provide the verbatims of the New Scientist article. The study in question was done by the Transport Research Laboratory in Crowthorne, Berkshire, UK.
As I mentioned earlier, this stuff is free, but since you have to register to access it I’m not gonna post the entire transcript of the article.
According to the article:
"The unpublished research, seen exclusively by New Scientist, stops well short of condoning driving under the influence of even small amounts of cannabis …
"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.
" … cannabis promotes conservative driving, but may cause attention problems and misperceptions of time," says Nicholas Ward, technical adviser to the Immortal project-a three-year European Union trial designed to quantify the crash risk drivers face after taking various drugs and medicines."
In short: Don’t drink and drive. Don’t toke and drive. Just drive.
