Now let's have a class in how to read a government propoganda website.
If you are someone who believes the government won't lie to you about the subject of marijuana, then the following won't make sense to you. But if you are someone who believes the government might just have a stake in misleading the public about marijuana, tag along while we look at NIDA's report.
Note first that NIDA is not permitted funding if they conduct studies seeking possible benefits to marijuana use. They are only funded for studies which produce conclusions or hypothesis that highlight the risks of using marijuana. The report below of course has no conclusions, but only poses theories.
*Marijuana use impairs driving-related functions and is linked to a pattern of behaviors that leads to poor job performance, according to two NIDA-supported studies on the effects of marijuana on human performance.
BAR: This introductory statement is not part of the actual study, but rather composed by the ONDCP.
* Figures from previous studies of automobile accident victims show that from 6 to 12 percent of nonfatally injured drivers and 4 to 16 percent of fatally injured drivers had tetrahydrocannabinol (THC), the psychoactive ingredient in marijuana, in their bloodstream, Dr. Heishman said. One study showed that 32 percent of drivers in a shock trauma unit in Baltimore had marijuana in their bloodstream, he noted.
BAR: Good solid facts. Now here's what is not shared. Marijuana THC metabolites remain in the bloodstream for up to 30 days. With this information, we know that about 3% of the drivers at most had actually ingested marijuana the same DAY as the crash.
*However, in most of these studies, the majority of subjects who tested positive for THC also tested positive for alcohol, making it difficult to single out THC's effect on driving.
BAR: It may have been difficult to single out THC's effect on driving, but it didn't stop the ONDCP from presenting it as causational effect.
*In a laboratory study at NIDA's Addiction Research Center in Baltimore that controlled for alcohol's confounding effect, Dr. Heishman tested marijuana's effects on the functional components of driving. Study subjects smoked a marijuana cigarette, waited 10 minutes, then smoked another cigarette. Both cigarettes contained either 0, 1.8, or 3.6 percent THC. Twenty minutes after smoking the cigarettes, the subjects were given a standard sobriety test similar to a roadside sobriety test. The test showed that marijuana significantly impaired their ability to stand on one leg for 30 seconds or touch their finger to their nose. As the dose of THC increased, the subjects swayed more, raised their arms, and had to put their feet down in an attempt to maintain their balance. Subjects also committed 2.5 times more errors when they attempted to touch their nose with their finger.
BAR: So this suggests that someone who drives within 10-20 minutes of using marijuana may be impaired. It does not account for the other literally 99% of the above statistical group who had THC metabolites in their bloodstream.
It also does not include mention of the basic scientific method which of course included alcohol users as a control group. So the results of this subset include both alcohol users and non-alcohol users.
This doesn't stop the ONDCP from using the entire group in the leading summation.
What this study shows is what most NIDA and government sponsored studies about marijuana show. And that is people in a certain subset - in this case, drivers who have had accidents - test positive for marijuana metabolites.
This information is then used to demonstrate causation, even though it simply shows a correlation.
If you've never studied scientific logic, this won't mean much. But I'll use a simple example to explain.
A group of people may be shown to have ingested milk prior to a specific event - let's say it's having an automobile accident.
Using NIDA's logic, we could then state, "Milk causes impairment for drivers, because this percentage of accidents had drivers with milk in their bloodstream."
The normal person would ask, "Hey, I accept your statistic about the milk, but can you demonstrate how it definitely impairs driving?"
In other words, an accurate correlation has been demonstrated, but the causation is very questionable. Note the quote from the study, "However, in most of these studies, the majority of subjects who tested positive for THC also tested positive for alcohol, making it difficult to single out THC's effect on driving"
So in an attempt to show some causation, they do the independent exams where they examine coordination 10-20 minutes after toking.
And from that, the ONDCP (not NIDA) posts as CONCLUSIVE that if pot causes impairment of coordination after 20 minutes, than by God, anyone with pot in their system from the past 30 days must also be impaired.
Here's a BIGG clue and tell me if this makes sense. (No, not you Truthteller, because you strike me as someone who buys government web information without question)
Do you think NIDA stopped testing after just 10 and 20 minutes?
Don't you think they also included tests that would examine coordination after 30, 60 and 120 minutes? How about 30 days after toking?
If it's reasonable to suggest they did do additional testing, then why wasn't it included in the summary report??
Well maybe because they did do the additional testing and they found that after 30-60 minutes, there's no measurable impairment whatsoever. And as I noted above, NIDA is not permitted to release information that may show anything favorable towards marijuana use.
~~~~~~~~~~~~
Now that we've seen the NIDA report for what it truly is...accurate information used to produce bullshit conclusions, let's return to the fundamental question TTeller asks, and btw, it's not an unreasonable question on his part.
"If there's some dispute about the findings, isn't it better to err on the side of saving a few lives?(by taking any driver with THC metabolites in his system off the road)?
And the answer is, Oh my god NO.
The proposed legislation at the federal level and in several states is to criminalize any level of THC whatsoever in the drivers system.
And even if we accept the NIDA information as acceptable for drawing a conclusive correlation, you've just made criminals out of 100 drivers, when in actuality at most ONE of them had ingested pot anywhere even near the defined 10-20 minute period where impairment was demonstrated.
CRIMINAL RECORDS DESTROY LIVES.
If someone is truly a danger to others and thus worthy of criminal charges, I'll be the first in line to support laws which help protect us all.
But if we're destroying lives based on such info as the NIDA report above, I am the first in line to denounce such junk science which if used, protects no one while destroying millions.
