Dexamphetamine absolutely does not show up on a roadside drug test. They test for methamphetamine, MDMA, and cannabis.
Yes I think it is very classist that they do not test for cocaine.
I disagree strongly with the drug testing window for cannabis. People are safe to drive relatively soon after smoking, within 6-8 hours at maximum.
MDMA I dont know enough about how the drug works to pass comments on this.
Meth I think the 48 hour window is legitimate and necessary. I use meth, and I know I am definitely still impaired from sleep deprivation up to 48 hours after use, maybe slightly even the next day. With meth it is important to remember they're also testing you for the fact that you will be impaired by sleep deprivation 48 hours after consuming it which is equivalent to being over the legal alcohol limit.
Anyone who tells me they're a good driver on meth or coming down from it is having a laugh. When I was a heavy user of multiple substances in 2017 I thought very little of getting into my car and driving to where I needed to go (often to get more drugs) because I just figured I'd never get pulled up. When I sobered up I got into my car 4 days after my last use of meth and it suddenly hit me I'd been driving under the influence all year without a care in the world and I felt a deep sense of shame because I could easily have killed someone. As I got into the car I realised the only way I could live with the guilt of doing something I viewed as so morally wrong was to swear on my life I'd not do it again.
7 years later and if I want more drugs I will wilfully drop $40 on an uber to get there and back safely without putting any other road users in danger or if I need to get home from work within the 24-48 hour window again it's an uber for me. I'll wear the extra cost to not feel the shame and the guilt.
If dexamphetamine showed up in roadside tests in Australia, prescribers would have to issue letters of approval stating that the person in question is legally prescribed that specific stimulant and hence they may test positive on a roadside test. As this does not ever happen (which I know as I'm prescribed it) and dexamphetamine is very widely prescribed for both ADHD and Narcolepsy, I think you'll find that we would be hearing a lot of complaints about people with disabilities being targetted due to their medication.
@PingaChew having scripted Dex makes no difference to anyone. It will never show up in a roadside test as they are designed to exclude picking up such a commonly prescribed medication. As a law graduate I can tell you that the courts do not have the time to waste hearing pointless charges against a person who had a roadside test come up positive because of dexamphetamine. It can so easily be disproven because they can show their legal prescription to the court and also if you test positive on a saliva test you then to a urine or a blood test. There is a special code they can put on the pathology request form which orders the technician to differentiate between stimulant types on the test, which will then definitively prove said person was on Dexamphetamine and not methamphetamine.
Put the entire process of doing that is arbitrary and a complete waste of time. They are not the same drug. Prescription meth is Desoxyn. That it an identical drug to methamphetamine. Dexamphetamine is not the same molecular substance, so the test will never pick it up.
If you are popping dexies to get away with smoking meth while you drive I would very strongly suggest you stop doing that because when they test your blood or urine you will come up dirty for both and you'll be toast.
Regarding your friend who came up positive, they had meth in their system and didn't want to admit to it. Bad luck to them. Probably would have been better not to rely on such an easily disprovable lie which the tests are designed to root out and ensure never happens.
The reason I know this about the tests? I have to do urine drug screens for my dexamphetamine because I'm a very naughty boy and the drugs of dependence unit had a notification of me shooting up heroin in June last year and I admitted to them I used to have a meth habit until I got medicated for Narcolepsy. They approved my dexamphetamine authority with multiple conditions, one of which is that I get piss tested randomly both by my GP and where I get my maintenance therapy injection.
The test at the maintenance therapy place is a cheap piss in a cup wait 5 minutes pull the label off quicky which does NOT differentiate between methamphetamine and dexamphetamine, because it does not have the technological capabilities to do so.
The test at my GP is *supposed* to include a code which orders the pathology technician to differentiate between methamphetamine and dexamphetamine, but when I was talking to my psychiatrist about how easy it would be for me to cheat the test and use meth if it didn't differentiate it, she told me to check for the code and it wasn't there, then informed me that it would in fact be so simple to cheat the test I could shoot up that morning, pick up the test cup, piss in it, and not get caught.
This is obviously a fact I've been mercilessly exploiting, but also my GP does not give a fuck if I use other drugs on my prescription and laughed at me when I told him I ate out of date valium before he called me a desperate druggy (he likes to roast me)
He just doesn't want me shooting the pills, collecting them and abusing them, or diverting them.
This is all correct and factual information about how urine drug tests work and can be manipulated to determine which specific opiate or stimulant a person uses, courtesy of the overlords at South Australia drug of dependence unit (may we bless their souls for granting me my goodies).
Take from that what you will, but I'm telling you there is zero chance in hell a person on dexies wouldn't be able to prove they didn't have meth in their system once it came to the second much more sophisticated test.
