The Truth About Driving When You're High on Marijuana

Concerns about stoned drivers careening across our nation's highways are frequently cited as a justification for the continued criminalization of marijuana. Given the massive casualties associated with drunk driving, it's easy to understand how the specter of increased roadside fatalities can be effective in reinforcing negative attitudes about marijuana. However, a new report reveals that, while stoned driving isn't smart, it's hardly the death sentence some would have us believe.

NORML's Paul Armentano has prepared a scientific review of over a dozen studies evaluating marijuana's effect on psychomotor skills and the risks posed by marijuana intoxication behind the wheel. Armentano finds that marijuana impairment is generally "subtle and short-lived," falling far short of the threats posed by drunk driving.
Although acute cannabis intoxication following smoking has been shown to mildly impair psychomotor skills, this impairment is seldom severe or long lasting. In closed course and driving simulator studies, marijuana’s acute effects on psychomotor performance include minor impairments in tracking (eye movement control) and reaction time, as well as variation in lateral positioning, headway (drivers under the influence of cannabis tend to follow less closely to the vehicle in front of them), and speed (drivers tend to decrease speed following cannabis inhalation). In general, these variations in driving behavior are noticeably less consistent or pronounced than the impairments exhibited by subjects under the influence of alcohol. Also, unlike subjects impaired by alcohol, individuals under the influence of cannabis tend to be aware of their impairment and try to compensate for it accordingly, either by driving more cautiously or by expressing an unwillingness to drive altogether.

Of course, the point here isn’t that one should get stoned and cruise the strip blasting Led Zeppelin. But this is information one would want if they were trying to create a smart marijuana policy as opposed to the disgraceful mess of legislative lunacy currently passing for marijuana law in America.

Whenever someone claims that marijuana makes you sick or crazy; that it will cause you to crash your car, kill your comrades, or catastrophically co-opt your common sense, just look for the corpses. Where are they? I've looked high and low, but I can't find the disastrous consequences of marijuana use apparent anywhere other than the Drug Czar's predictably propagandized press releases.

But to be fair, there are two horrible things about marijuana that everyone should be mindful of and they are as follows: 1) the smell attracts cops, nosy neighbors, and mooches and 2) the stuff remains detectable in your system for up to a month, thereby enabling various authorities to become needlessly aware of your activities.

If not for these two unfortunate conditions, the marijuana war wouldn't even begin to work, and the blockheads who've been bothering to fight it would've wandered off decades ago.

In November 2006, 92-year-old Kathryn Johnston was killed by police during a raid conducted at the wrong house. Ms. Johnston fired at the police officers as they were breaking in through her living room window. Three officers were injured, but Ms. Johnston was struck 39 times and died at the scene. In July 2007, Mike Lefort, 61, and his mother, Thelma, 83, were surprised and thrown to the ground when Thibodeau, Louisiana police burst into the wrong house with a "no knock" warrant. Thelma suffered from a spike in her blood pressure and had a difficult time overcoming the shock. In March 2007, masked police officers in Jacksonville, Florida, mistakenly burst into the home of Willie Davis, grandfather of murdered DreShawna Davis, and his mentally disabed son. The pair were forced to the ground, where they watched helplessly as police tore apart the memorabilia from DreShawn's funeral. The drug sale that never happened was said to involve all of two crack rocks worth $60.
One would think after Atlanta police killed 92-year-old Kathryn Johnston, that they would get the idea, but they haven't. Last Friday, 1/4/08, a SWAT team, serving an ordinary drug search warrant, invaded the Ohio home of Tarika Wilson -- an innocent woman -- shot and killed her, and shot her one-year-old son. "They went in that home shooting," her mother said at a vigil that night. The boy lost at least one of his fingers. Two dogs were shot too. SWAT teams were created to deal with extreme situations, not routine ones. Yet police now conduct tens of thousands of SWAT raids every year, mostly in low-level drug enforcement. The result is that people like Wilson and Johnston continue to die in terror, with many thousands more having to go on living with trauma. But it's all for a drug war that has failed and can't be made to work. It's time to rein in the SWAT teams.
