A breathalyser test for marijuana

A breathalyser test for marijuana

Stanford researchers have used magnetic nanotechnology to create what could be the first practical roadside test for marijuana intoxication.

Point being ?

Is there a 'legal' limit of weed in the system ?

Weed is illegal, so there should be a zero tolerance I am guessing.

Pretty sure the legal limit for any illegal substance in your system, while operating a vehicle, is zero.

Sure - why not? :confused. Colorado, for example, has a limit five nanograms of active THC per milliliter of whole blood.

EDIT:

Six states have set legal limits for THC concentration in the blood. California is not, however, one of them.

EDIT2:

9 states have zero tolerance for THC or a metabolite.
3 states have zero tolerance for THC but no restriction on metabolites.
5 states have specific per se limits for THC
1 state (Colorado) has a reasonable inference law for THC

Well, one could be 'amongst' weed smokers and 'accidentally' inhale some second hand particles....

Hopefully the potheads don't try to smoke it unlike this old man with an alcohol one.

uh... not globally.. and for here, its just a matter of time...

there are states/countries where it is completely legal.

I thought he meant for here.

I wonder if it would pick up the cancer oil as well?

I don't think Stanford's primary focus is the South African market…

No it wont. Well depends really. Some oils, are high in CBD and really low in THC. Many of them are diluted quite heavily as well. It would be akin to having a shot of beer before driving somewhere and being tested imo. The actual amount of CBDs required to gain from the medicinal value is so low that a breathalyzer wouldnt pick it up.

You get more concentrated THC based oils though that could definitely trigger it, especially if enough is taken in to get high off.

Wasn't taking it in context of the article exclusively. I thought he was asking, if there is a legal limit here in SA, if the device comes this side.

Also it is stanford*

Thanks - that one of those words I always seem to misspell. Blaady Stamford, Connecticut…

If this is used in the same way to screen for illegal blood-alcohol levels, great. This tool is a step in the right direction for ensuring people do not operate dangerous equipment of enter dangerous areas when high.

Oh..wait..this is still September 2016 where marijuana bluntly is illegal.. Disregard.

Accurate marijuana breathalyzer being tested

This is a good thing imo, if it works properly and accurately.

A new marijuana breathalyzer that immediately detects THC levels could bring them one step closer to regulating marijuana-related impairment on the roads.

Unlike breathalyzers that may simply detect the presence of THC, the Hound Labs device detects the levels of THC in parts per trillion. "That gives us a very precise amount of THC in the breath. That number, that measured level will ultimately be correlated to driving impairment at roadside," Lynn said. "Any legislation related to impairment needs to reflect true data."

THC in the breath only shows up within about the first two hours after people smoke, Lynn explained. "You can smoke every day, but if you haven't smoked for a few hours we're not going to detect it and measure it. That's the time period that correlates with maximum impairment," he said.

"It's critical for protecting people who have the legal right to smoke cannabis. Whatever you did last night shouldn't frankly impact you getting arrested the next morning if you're not impaired. That's the problem with urine, blood, and saliva tests."
