UK Driving Drug Test....

I read it was 14h for cannabis, not sure about cocaine.

The BBC say 36 hours here http://www.bbc.co.uk/news/uk-31683571
Thanks for providing that info, I've tried quite hard to find more information on the actual limits and there's not much out there to be honest.

The only thing I'd point out to those reading this is that David Taylor has been a bit misleading when he said 'any exposure would render people over the limit... for up to 36 hours' because even the eight 'zero-tolerance drugs' have been given a slight threshold to account for any 'accidental exposure' - i.e. the threshold set for Cannabis is low enough for it to be easily detected in blood samples, yet high enough to account for any light passive smoking.

You've provided some very useful information on this subject mate - thank you. :)
No worries! It's an interesting topic and I'd hate for anyone on BL to be caught short of the law by accident.

Though if someone's deliberately getting behind the wheel on their way home after a Ketamine binge, I think I'd prefer them off the road and wouldn't have much sympathy for them. Same as I wouldn't sympathise for someone who knowingly drove whilst heavily intoxicated through alcohol.

It's the people who are going to be perfectly fit to drive, yet possibly caught by the law because they have 'old/inactive' substances still inside of them that doesn't sit very well with me.
 
Drug driving laws introduced in the uk March 2nd - specifically cannabis - please hel

Hi all

Today is a really dark day!

I have smoked cannabis for 5 years, i am a productive member of society with a job and a car.

As of Monday 2nd March the UK police have the ability to test for cannabis and other drugs at the roadside, if you test positive, you will be banned from driving.


The test will be performed via an oral swab with a machine called "drugalyser" the limit for cannabis is 2mcg/litre of blood.

I am perfectly happy to not drive when i am high. However according to the following study, 4/6 people test positive 22 hours after smoking a spliff.

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3717347/

"10 participants provided 86 OF samples −0.5 h before and 0.25, 0.5, 1, 2, 3, 4, 6, and 22 h after initiation of smoking. Before smoking, OF samples of 4 and 9 participants were positive for THC and THCCOOH, respectively, but none were positive for CBD and CBN. Maximum THC, CBD, and CBN concentrations occurred within 0.5 h, with medians of 644, 30.4, and 49.0 μg/L, respectively. All samples were THC positive at 6 h (2.1–44.4 μg/L), and 4 of 6 were positive at 22 h."

Would your experience in australia suggest this study is true? I am not a scientist, but i cannot see how this study would be wrong or irrelevant?

the worrying ting is you may pass the drug driving test but will you still be arrested for having drugs in your system? I take gear or methadone everyday and apart from being an arse where i was driving nodding out and rear ended another car- have never crashed as a result of drugs.
 
Thank god I rarely smoke canibis these days. My only worry is when I've had speed or mdma and how long its detectable for. Can see there being a lot of unfair convictions for this, if I ever got done I'd fight it all the way and take it to court if I have to.
 
I once smoked cannabis after a 4 months break and got saliva tested approx 1 hour later. This was at an engineering college and they got someone in to test us.

We was all sat in a room while we waited to take the test, they said do not drink or eat anything for the next half hour.

I drowned myself in powerade and chewed a few wrigleys and passed.

I have no idea if they helped though.
 
Having drugs in your system is not actually an offence. As far as British law is concerned, ingestion is destruction.

Thats the whole point of the new law - having a certain amount of drugs in your system will be a criminal offence if your driving and thats just a small step away to having any amount..
 
It bothered me in case I was to crash a works vehicle (which due to the ways marked blue light vehicles are legally allowed to drive is pretty common).

While what I was taking was prescribed I still could forsee potential hot water if I wrote of a £170,000 ambulance and was found to have large amounts of (prescribed) opiates in my system.

And I knew for a fact the service would just drop me like a stone if the shit hit the fan..... One of my many reasons for coming off actually.

Yes, but it will only be an offence if you are in charge of a motor vehicle.

Also, testing for non-psychoactive metabolites that could plausibly have resulted from endogenous compounds is pretty much asking to get challenged and overturned. As Howard Marks put it, "You've just got to hope and pray -- and the odds are just slightly in your favour -- that there are at least two people on that jury who smoke dope."
Who cares?????
I think you are being a bit short-sighted, Evey. Although there is no way you or I personally are ever going to run directly afoul of this new law, it is still capable of affecting us indirectly. My hard-earned is still being spent chasing a pipe-dream for the appeasement of Daily Mail readers, purchasing proprietary technology whose sole purpose is to enrich billionaires; and while the police are occupied arresting motorists, real criminals -- and ones who would still be sent down if the requirement for mens rea still applied -- are getting away with real crimes.

What we really need are meta-laws, governing what sorts of laws governments can pass. Published manifesti only go partway towards this goal, since even governing parties have conferences and update their policies while in office and there is no penalty, after being voted out, for failure to execute manifesto promises whilst in power.
 
Obviously I don't want anyone to fall foul of this new law and yet more erosion of our freedoms but it will be interesting to see how it pans out for the unfortunate victim...

OTW has mentioned that discretion is used in Oz but I can't imagine that happening over here, not for a good while anyway whilst the toys are still new and shiny..

Seems the perfect time for me to get off opiates anyway and lucky for me my other love LSD is virtually undetectable :D

EDIT

And here we have one of the very first arrests with the drugalyser.. North Wales Police to, they does love to punish the motorist in Wales so it comes as no surprise...

The lad did crash though so he more than likely was driving whilst he shouldn't have been..

Not so fast scotch - LSD is tested by the new drugalyser blood test - at 1microgram. Presumably if you've tripped the night before you will still be positive the following day?
