No, urine or blood cannot be used to activate Vyvanse for a high. Vyvanse (lisdexamfetamine) is a prodrug, meaning it must be metabolized in the body to become active. It is designed to be taken orally and converted into its active form through the digestive process. Attempting to use urine or blood in this manner is ineffective and dangerous.
Vyvanse show up in both urine and blood tests as an amphetamine.
Vyvanse will show up as an amphetamine in both urine and drug testing.
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).
Usually no more then a week, but to be completely sure I would say 2 weeks.
Yes, both through blood and urine testing.
48 hours depending on how much taken
No, but they will test for the broader category of amphetamines, and both Aderrall and Vyvanse will result in a positive amphetamine result on a drug test.
Yes, it will. It will show up in both blood and urine tests as an amphetamine.
To activate the methods to produce urine
Vyvanse is not approved for use in India, as it is not listed in the country's regulatory guidelines for pharmaceuticals. Therefore, it is not legally available for purchase or use in India.
No...it does not show up as PCP. But it does in fact show up as an Amphetamine.
