Is it possible to test positive for methamphetamine without testing positive for amphetamine It would seem that it isn't possible unless false positive since amphetamine is a metabolite of meth.?

YES IT IS ,THERE ARE AMPHETAMINES,THEN THERE IS METHAMPHETMINES ,THE DIFFERANCE IN THE TWO IS IN THE CHEMICAL PROCESS,OR THE WAY IT IS MADE. AND YES YOU CAN TEST POSITIVE FOR METH WITHOUT TESTING FOR AMPHATAMINES

Is Adderall an amphetamine or a methamphetamine?
No, Adderall is not considered METHampehtamine. Adderall is a combination of four amphetamine salts 1 racemic amphetamine aspartate monohydrate, 2 racemic amphetamine sulfate, 3 dextroamphetamine saccharide, and 4 dextroamphetamine sulfate Adderall works as a reuptake inhibitor for dopamine and norepinephrine. Amphetamine is the name for the chemical compound: methylated phenylethylamine. Methamphetamine is the same thing, but it is double methylated, instead of only methylated once. Because of the double methylation, meth has a stronger, FASTER, effect on the body (not longer lasting). The strong/fast effect is what causes extreme chemical/physical dependence and addiction. It is worth noting that methamphetamine breaks down into amphetamine when it is metabolized. This means that meth turns into amphetamine in the body, and is excreted as amphetamine. Finally, amphetamines are very similar to nor/epinephrine, naturally made phenylethylamine substance from human adrenals. synthetic versions can/do severe damage to the sympathetic autonomic nerve system (e.g., cause of myocardial infarctions, rage/violence, etc.). (note: "racemic" means mix of both levo and dextro enantomers of the chemical moity. "dextro" means right 'handed', levo means left 'handed'. Important since some drugs have only a certain shape (levo or dextro) that are effective, and some a mix of both is most effective).
If you are taking Amphetamine Salts will you test positive for Methamphetamine?
Yes. Other amphetamine drugs can as well since they are in the same class of chemicals, such as Vyvanse, Concerta, Ritalin, Adderall or Desoxyn, which are prescribed for common disorders such as AD(H)D.
What is the difference between amphetamines and methamphetamines?
Methamphetamine is "methylated," meaning that it is water soluble. This means it is more quickly absorbed by the human body and can be injected than non-methylated amphetamine. Otherwise, there is no difference. In fact, methamphetamine breaks down into amphetamine once it's ingested. The outer membrane of the neuron cell is water soluble, this methylated property along with it's molecular size allows the chemical to pass through this barrier and influence the chemical messenger's or neurotransmitter's, (serotonin, dopamine, etc) receptors agonisticly. I think methamphetamine breaks down to amphetamine once it is metabolized or biotransformed. This isn't correct. Methamphetamine is methylated, and there for it is now more fat soluble. Meaning that it crosses the blood brain barrier much easier, without having to circulate through the blood over and over again to be absorbed into the brain. When it comes to dissolving in water or ethanol. It has to do with the PH of a compound. Meaning which physical form it appears in, either a salt or freebase compound. Salts are typically water soluble making it possible to iv or snort. Freebases usually have lower vaporization points making them easier to smoke. Like crack compared to cocaine.
What does Ritalin shoe up as?
Ritalin contains methylphenidate. This compound has a structure that is distinct from stimulants such as amphetamine and methamphetamine. Thus, Ritalin shows up only as methylphenidate, not other stimulants. This drug is not commonly tested for, though it is certainly possible to test for it.
Will zantax 3 show up as an amphetamine?
someone took a 5 panel urine analysis test and showed positive for amphetamines taking only zantax is this possible?
Is amphetamine in over the counter cold medicine?
Not exactly.... but Sudafed contains pseudoephedrine, which is very similar to methamphetamine in molecular structure. Don't get too excited though, the drug is designed to not get into your brain, so it will not cause any of the dangerous or abusive effects that meth can cause. It will clear your nose quite well though!
Your brother takes methadone for back pain and had to do a drug test and came back positive for amphetamines is that possible?
No. Methadone is classified as an opiate. If your brother is testing positive for amphetamines, it is a completely different drug classification, and he is taking some sort of amphetamine.
When taking Adderall will you fail youe drug test for weed?
its possible if you are only being tested for methamphetamine, though this can be solved through gc/ms testing. adderall contains a mix of amphetamine salts. the amphetamine molecule is broken down into two isomers, levo amphetamine and dextroamphetamine. Adderall is made up of about 71% dextroamphetamine, the rest is levoamphetamine. through gc/ms they can break it down and see that you have dexro and levo and not the methylated version. of course this is redundant if you don't have a legal prescription for it.AnswerThe thing about Adderall is this: It's made out of amphetamine, which is always tested for. If you're taking Adderall and you're not supposed to be, you'll get nailed for amphetamines.
Does Ritalin show positive in a urine drug screen?
Ritalin can show up as a "positive" for amphetamines on drug tests.
How can methamphetamine show up in your system if i don't smoke meth?
Methamphetamine can be detected in a drug test even if one does not smoke/abuse meth. One way this is possible is that methamphetamine was ingested in another way, such as orally in the form of prescription pills (Desoxyn is a prescription form of methamphetamine hydrochloride). Certain decongestant inhalers also contain an isomer of methamphetamine. Though this compound lacks the abuse potential of its enantiomer (non-superimposable mirror-image molecule), it may still show up as 'meth' on a drug test. Finally, other medications can also cause false positives for methamphetamine on certain tests. If one test gives a positive result, more advanced tests can be used to distinguish between positive results and false positives. If one has used the aforementioned products which contain methamphetamine, this should be brought to the attention of the test administrator.
What over the counter cold med shows as meth in blood as test?
There is no cold medication that shows up as Meth on a drug test. Sudafed is used in the manufacture of Meth, but taking Sudafed will not make you test positive. While there are amphetamine based meds on the market, the test is looking for certain chemicals uniquely found in Meth. However, since meth is an amphetamine based drug, it is possible that a drug test could show a positive result if you are taking amphetamine based medicine. A drug test should not show a positive result in those circumstances, however not every manufacturer makes their tests the same. It would be your responsibility to inform the tester if you are taking amphetamine based meds PRIOR to the test.
Does crystal meth pose risk of overdose?
Yes, it is possible to overdose on methamphetamine. Though a methamphetamine overdose can be treated with medical care, it is serious and potentially fatal.
