Yes it can! I've had it happen to me before and it showed up as coke.
Nope. However, it will come up as amphetamine, which makes sense since it is.
Yes!
NO. Venlafaxine is in no way related to Opium. It is an anti-depressant and is not at all considered an opiate.
Vyvanse will show up as an amphetamine in both urine and drug testing.
Cocaine
It will show up as Amphetamine (whether legal: adderall, dexedrine, and vyvanse, or illegal: speed). Unfortunately they can not tell which you took, all it is to them is "AMPHETAMINE". SO unless you have a valid prescription you should be fine (not in all cases).
Vyvanse show up in both urine and blood tests as an amphetamine.
No. Vyvanse is an ADHD medication and is classified as amphetamines. You will fail a drug test for amphetamines, not PCP. It is highly unlikely to fail a drug test for an illegal drug (cocaine, pcp, etc) by taking a prescription drug. The only example of this occurring is failing for methamphetmine (illegal---crystal meth) when you have only taken ampethamine (legal with prescription---adderall, vyvanse, etc). This depends on the type of test you take. Some tests cannot tell the difference.
No. Cocaine will show up as cocaine, adderall will show up as amphetamine.
Yes; Vyvanse is a prodrug for dextroamphetamine. Vyvanse contains a bonded chemical containing dextroamphetamine and l-lysine.
Xanax is a benzodiazepine (chlordiazepoxide) and will show up as such. It will not show up as cocaine.
12 to 14 hours
depends what kinda drug test it is.. if its a base line your levels will just be higher if it tests for coke it will show up as coke.
Yes, it will. It will show up in both blood and urine tests as an amphetamine.
