a false test can be from a cold medicine. you have no idea how pseudoephedrine is so close to illegal drugs.
what medications cause a false positive on a drug screen for marijuana?

I don't know that you can make it read a false positive, but sometimes it just happens to read as a false positive.
no
Using someone else's urine, who has used pot, for the drug test would give a false positive.
No.
no

Yea. The Fastin XR will show as MT on a 12 screen panel
Yes! Lamictal will show a false positive on drug screens. You can have a lab use a maspectrometer specifically for PCP in order to officially rule it as a "false positive."
Tramadol is not an opiate. It is an opioid, which is a synthetic opiate. It will not show up on a basic drug test. Naproxen will not give a false result for opiates on a drug test. It will give a false result for marijuana.
