Nothing causes a false positive for Amphetamines. The only possibility of something that might would be Sudefed or some derivitive of it, but even then, I doubt it. Those tests are pretty specific.
no it should not as seroquel is a benzodiazopine which is not related to amphetamines
will clonidine come up positive on drug test
No.
yes
no
probably not, because amphetamines are a controlled substance. and they don't do tests for nicotine, so you'll pass
All of them
Hydrocodone is an Opiate based painkiller, so no, It cannot test positive for Amphetamines - but it will on the other hand, Test positive for Opiates (Heroin, Morphine, Oxycodone ect.)
No, it WILL cause a true positive for amphetamines.
No
No. Amphetamines are controlled substances and can only be distributed with a prescription from a doctor. It has been known in other countries with different laws, that amphetamines are contained within energy drinks. An example country which I know this is true, is Thailand.
Clonidine.. like, the candy? I don't know, it isn't a drug, is it?
