For everyone who does meth: how long after taking meth is it safe to drive? My friend wants to try meth but is worried that he will get tested (we are talking 12-24 hrs after ingestion atleast). I thought that meth is only detectable in saliva within 8-12 hrs of ingestion and only 48 hrs for urine. I would like to pursuade him (not to do meth, I am technically against him doing it because I'm a hypocrite) that it is safe to assume that if he would coincidentally get tested with a new ultra rare amphetamine specified saliva swab he will be safe. He has not yet gotton his full lisence and therefore this is VERY important. I would feel responsible if I told him he was safe and he ends up loosing his lisence. Please list sources for your information, I have some, but they aren't very specific (about amphetamines and driving). Thanks in advance.

i don't think you'll be driving down the road, and a cop will just be like "oh that guys on meth get'em!"
unless Aus. is totally diff from US and they do that, which in that case go to a park for the day or a museum is pretty fun too, ime.

The only source I found was http://www.drugsdriving.adf.org.au/browse.asp?ContainerID=dd_laws_drugs and it says something like 3-6 days. It says that on erowid to, so I doubt a day in the park will change your blood levels significantly. In Australia they do test for amphetamines, methamphetamines, methylphenidate, cocaine, morphine alcohol and marijuana (technically only THC). I think that's all but I could be mistaken. The problem is that if any of these drugs (except for morphine because codeine is OTC and metabolized into morphine) is found in your body at any level, you're in deep shit because they are illegal. It doesn't really matter if it impairs youre driving skills or not, amphetamines would only do this if you are insanely high or havnt slept for days, it's a convinient testing method. Although I do have to say that compared to the USA we have much more relaxed rules.
In the show "RBT" or whatever which I wanted to catch for 'research', it showed dudes who had "a little" (one smoke and/or one line/bump I think) being done for driving on drugs the day after because the guy(s) were saying stuff like "Wow? I only had one *insert consumption way*, I thought a day would be fine as I've had a sleep" etc etc.
So, from actual evidence of people being done on the next day, I would say someone can easily be done for "drug driving", lame because no whatsever impairment may be happening but still able to lose your licence for whatever time period plus a fine? Not worth it imo

Methamphetamine has a 9-12 hour half-life, so depending on how much you've done can be detected for a few days afterwards.
I'm not sure about the saliva test kits the police use, one retail kit I'm looking at on the net right now detects concentrations of 30 ng/ml. I'm sure someone here could do the math better then I could.
ETA: The tester I am looking at does not test for methylphenidate specifically, but it can produce false positives for amphetamines and so it would be wise to keep your script with you.
This tester can also detect diazepam...hmm...

So, do you know how long it takes to finally be able to drive again? There is no way that I will take speed with someone who who has to drive under the influence.

Yeh I wouldnt drive for at least 24-36 hours. You may feel like your fine to drive but your really not and you will get caught if they swab you. Meth is the one drug that me and all my friends feel that we would be fine driving on but once you come down and realize you really were waaay more off your head than you realized, then you realize how much of a bad idea it would have been to go for a drive. Meth makes you feel like your more alert but most of the time that is incorrect.

while we're on this subject. Whats the general consensus of doing 4mar and getting tested ???
Would you be getting a false positive to Meth????

^ It may give a positive for amphetamine, but the confirmatory test should come up negative because as far as I know no one actually looks for 4-MAR in drug screens.
I.e., say you went through a saliva drug test while driving, it could come up positive. They will then do a blood test in the van, but I highly doubt they will check for 4-MAR then and they won't find amphetamine.
I got this information from another forum where a user claimed to have contacted the manufacturers of the drug tests they use. You could get in contact with a manufacturer yourself to confirm.

I think how 'safe' it is to drive on meth can vary greatly depending on individual tolerances, quality of the meth, the doses being taken and how many days one has been up for. They give amphetamines to fighter pilots, they give them to kids who can't concentrate in class, it is pretty clear that at the right dose amphetamines improves ones ability to concentrate and arguable operate a vehicle.
However a typical recreational dose of amphetamines is likely to be higher than an optimal dose for improving concentration, in many cases a lot higher. How much increasing the dose starts to impair ones driving ability is hard to determine, one thing that must be said is amphetamines increase the users general confidence and overconfidence is a big cause of accidents on our roads.
I personally think you have to be pretty fucking high on amphetamines before it would impair your ability to drive a great deal, but who am I to determine a reasonable amount of impairment for drivers on our roads.
When somebody has been up for a day or more it becomes a different kettle of fish, someone in this state is in no safe position to drive and no increased alertness from more meth is going to help that.
Regardless of how safe or unsafe driving on meth is, I certainly think it is grossly unfair that you can be charged with this for days after your last use of meth. It is a total injustice to take someones licence away on the grounds of drugs that they consumed days ago are still in their system, despite the fact they are not affecting the driver. I am hardly an expert on road side drug testing but I have always thought it was generally 2 or 3 days after using you could get caught. The truth is individual metabolisms vary and 2 people could use the same amount of meth at the same time and both be tested a couple days later and one pass where the other fails. These drug tests are far from infallable and have a reasonably high rate of false positive indications.

I think the real question is how many cops patrol your area?
Nah to be honest i always thought methamphetamines would the one drug that would get out of your system the quickest... not to mention not every cop on patrol carries swab tests.... were usually havin pips in my car 80% of the time which usually includes a 50km drive afterwards lol

^ There are many who have gotten away with much more than they should, I personally know of many people who constantly drive on drugs and/or drunk but have never been caught. On the flipside of the coin, there are those who use drugs and/or alcohol rarely behind the wheel and get caught. It really is luck of the draw.

^ Yeah thats for sure... ive also had my fair share of close calls, the worst being the cop knew me n my mates were off our head (4am) and i even tryd avoiding them on the road but yer, he ended up jokin around about bongs, lol, and he let me off because i blew 0 on the breatherlizer (Had half a carton of VB around 10 hours prior to this 
)

They only test the 3 on roads in Vic. That's all I've ever seen when pulled over by a booze/drug bus. I have been told weed is detectable up until 12 hours afterwards, but have no info to support that other then myself being pulled over the next morning and nothing showing up.
With meth though I have no idea

There a study being done recently at the University of Sydney on the effects of amphetamines on drivers and coordination. I'm not sure if any results have been published though. I'll have a look around in the next few days to see if I can find links:

I agree with the fact that meth is unlikely to impaire you're driving skills if you're not completely off it, however I think that no one should drive under the influence of anything ever and one thing I agree with is roadside drug testing. Many people who are irresponsible enough to drive high will not think "oh, I'll just get a little high so that it's safe to drive", they go all the way and that's endangering innocent lives which is unfair. Apart from that, the risk of loosing you're license is not worth being high. Thanks for the replies everyone, you have been a great help.
I have one more question though, how much meth made you hallucinate? I have taken meth a few times (not a big fan, I prefer heroin) and have only experienced slightly swimmy vision. Is it common to hallucinate on meth? Oh and by hallucinate I am not talking about the proper definition (altered perception) i'm talking about seeing elves type of shit.
