At least two weeks ... maybe up to a year
With drinking lots of water and going to the bathroom three days or so .
up to 3 months depending on how frequent the person uses the drug... heavy users can last a bit longer

a urine test that checks for THC, cocaine, amphetamines, methamphetamine, and opiates
It can. Higher urine concentrations of ranitidine can trigger a false positive. In the study I'll attach in the "related links" section below it was seen in people testing the first two voids after taking the drug and only with the monoclonal EMIT d.a.u. amphetamine/methamphetamine immunoassay (ME). This did not happen with the polyclonal EMIT d.a.u. amphetamine or TDx amphetamine/methamphetamine II assays.

No, a urine drug test has only recently been developed for HGH, any standard urine drug test will not test positive for it. This is amount of HGH in urine is miniscule, which is why it is so difficult to detect.
