Field sobriety tests, test motor skill impairment, such as a diabetic who has not taken his insulin, a boxer after a sparring session or me after a WOD when I have not had enough to drink. They are a far cry from a breathalyzer style test, that shows actual blood alcohol levels. @pardus I stand corrected. According to the article you linked to, there is a time when the blood levels can be high enough to show immediate use and intoxication. It did not, however, say if a field blood test was available. My question stands.It's been done for years as even though it has yet (Cannabis) to be completely legalized, and if you think it's the only thing other than alcohol shown in direct correlation to cognitive impairment, add in all the others, such as hallucinogenics, analgesics, anesthetics, etc. Operating a motor vehicle and exhibiting signs similar to those of alcohol impairment. Of course, most officers have some funny experiences with stops like this. You get stopped, I walk on up. I tell you to roll down your window and it's like Cheech and Chong times 20 have been inside the vehicle along with you....
Reasonable suspicion begins at first observation, such as swerving, sitting there at an intersection and the light cycles more than once and you haven't moved, failure to maintain your lane integrity and others, then continues during personal contact once the fumigation cloud clears up and beside the driver. Then you get the usual SFST's. HGN, VGN, pupil dilation, Divided Attention, and observations pertaining to interaction, slurred speech, blood shot eyes, and performance results based on the tests administered. Granted, nystagmus isn't always present in THC use alone, however, from my standpoint, you may be over lapping (Impairment from more than one substance)
Implied consent for either an alco sensor and or intoxilyzer, and or by warrant (If not by consent) for blood and oral samples for concentration levels. THC concentrations usually between 5 and 10 ng/ml can be shown to establish a pretty good case regarding THC limit for showing threshold impairment combined with all the other results and the officer's testimony.
Many variables exist which make it more difficult to detect, such as body mass, diet, frequency of use, tobacco users etc. But most officers, based on their training and experience have been down this road....a lot.
If you think this is something new, think again.

A. Driving under the influence of marijuana will remain illegal. A vehicle operator also is not allowed to smoke while driving.
Anyone with whose test results show five nanograms or more of delta 9-tetrahydrocannabinol, known as THC, per milliliter of whole blood while driving can be arrested for DUI.
The blood test is designed to tell how high a person is at the moment, not whether they have been using pot in the past several days or weeks, like urine tests that some employers use.
The blood test measures active THC in the blood stream while the urine tests measure a metabolite of THC, the form it takes after being broken down by the body.
Colorado law allows drivers to refuse the blood test. However, that comes with harsher penalties than a DUI.
If police have a reasonable suspicion that a driver is high on weed, an officer will likely ask the driver to take a roadside sobriety test, which is the same test given to people suspected to be under the influence of alcohol or other drugs. If the driver fails or refuses to take the sobriety test, then the officer will have to decide whether to arrest the driver and conduct a voluntary blood test.
Lewis said samples used for the blood tests will be taken by medical professionals. He added that an ambulance could be called to the scene to take the sample, or a driver could be taken to a nearby emergency room to have the blood drawn.
Drivers can decline to take the blood test, but Lewis warns that refusing it could lead to harsher penalties in some respects.

The results of the blood test could take two to six weeks to come back, according to Lewis. The legal limit of THC -- an active ingredient in marijuana -- that Colorado drivers can have in their blood is 5 nanograms per milliliter. That's a limit that Allen St. Pierre, the executive director of the National Organization for the Reform of Marijuana Laws, calls arbitrary and inaccurate.
"Measuring five nanograms does not measure impairment," St. Pierre said. "You can have individuals who have stopped using marijuana two weeks ago, two months ago. In some cases, if they were losing weight, they could still test over 5 nanograms."
Lewis said he has heard the criticisms of the marijuana DUI law that passed last year, but officers will only use a blood test after they have observed the driver being intoxicated.
Starting this weekend, law enforcement in Los Angeles will begin expanded use of saliva swab test kits on drivers suspected of driving under the influence of drugs. The change comes just in time for New Year's Eve celebrations.
The testing is already used at some LAPD DUI checkpoints and at three stations that have jails. A $520,000 grant awarded to the L.A. City Attorney’s Office will expand the regular use of the test next year.

The oral swab tests can detect tetrahydrocannabinol or THC – the active impairing ingredient in marijuana – that is in a person’s system up to three hours after ingestion.
5 nanograms of THC in the bloodstream is easy to achieve based on what could be stored in the fat. It has nothing to do with actually being currently under the influence. According to the article the @pardus posted 110 to 140 nonograms show actual recent use and intoxication. The swab test only shows use, not level. Field sobriety tests do not show level or even use. They are all stop gaps. I'm willing to bet that accurate forms of testing current THC intoxication in the field are in the works since more states may start to decriminalize the use of Marijuana.From USA Today:
From WPTV:
Referencing my earlier post, it's not Colorado who's been using the roadside swab test, it was LA. From the Southern California Public Radio website:
Does this even remotely answer your question?

Stop using big words! I have a headache. Not saying the stop gaps can't work, I'm just wondering if a foolproof field test to determine actual current level of intoxication, such as we have with BAC is coming. There is no argument here, why is everyone trying to argue? Ugh.
Reed
It was in reference to the overall harmfulness of mj.So not to be a dick, but why would juvenile tests have any bearing on the legalization and health risks posed to the population who would be affected, which in this case is adults.
How much you want to bet, that now that ALL use is not illegal, someone will be able to test for THC intoxication? I.E. a way to bust MJ buzzed drivers.

I'm posting the study more to support my claims that MJ damages the human brain, not necessarily as an argument for-or against legalization. In other words, I made the claim, and it was undercut as unfounded opinion. Well, much of the content of my post are opinion, but they are not misinformed. Marijuana as is most commonly consumed damages the brain. When, how, how much, at what age, all that is open to further study.It was in reference to the overall harmfulness of mj.
I don't want to parphrase @JBS , so adjust if I am off here- you were trying to establish the overall harm of mj, and were using the info you had on harm to adolescents as some sort of support to that claim. I inferred you meant to say, "If we legalize mj, adolescents will be at greater risk because they will have more access, and here are the studies to show that it is, in fact, harmful."
Adolescent usage shouldn't enter into the discussion. We're talking about legalizing it for adults, not selling it at Walmart next to the Doritos. I don't think it unreasonable to believe that similar safeguards/ restrictions in place for alcohol or tobacco will also apply to mj. As for kids getting their grubby paws on the drug, no one uses that argument to consider banning alcohol or tobacco, but curiously they use it to ban guns or place greater restrictions on firearms.
If we're talking about second hand smoke, again...why doesn't that argument apply to tobacco?
We can't go down one path without going down the other.
Honestly, if states are so fired up (haha!) about legal weed and how that will impact society, let CO and WA act as test cases. In 2-3 years everyone will see those states as either cutting edge or ground zero for the apocalypse.
The legalization of marijuana is not comparable to legalization of cigarettes, alcohol, or any other controlled substance, because these other substances presently do not have the backing of popular culture.
Seriously? That might be one of the most baseless comments I've seen in a while.~SNIP

To be fair, I can name two: "I'll never smoke weed with Willie again" by Toby Keith, and "Sunday Morning Comin' Down" by Johnny Cash.Seriously? That might be one of the most baseless comments I've seen in a while.
I can name one country song where a reference to MJ is made. Want to know how many I can name that reference alcohol?
As goon175 pointed out, movies are very much the same.
I was speaking personally. I guess I'm not as hip as I imagined...To be fair, I can name two: "I'll never smoke weed with Willie again" by Toby Keith, and "Sunday Morning Comin' Down" by Johnny Cash.
