I have a pre-employment drug test sometime in the next week (I think...they haven't given me a date)

I have a Rx for cannabis, as I was diagnosed with brain cancer last year (but im in remission and im fine now But I am still a daily smoker and my metabolism is NOT fast by any stretch of the imagination.
I'm so desperate for assistance! Please read and reply of you have had success or failed and can advise against a certain brand.....

Before posting this I read many threads on dilution, substitution, and detoxing.
My first instinct is that substitution would be the best since diluting or using a cleanser might be detected if it makes my urine too water-y or gatorade colored/ smelling chemically.

However, some of the substitution posts were discussing condoms and bag ties and getting urine from someone smoke-free I do not know anyone smoke free who would be not freaked out by my asking them for urine!

My question is, is there anyone out there who has used synthetic urine and failed or gotten caught??
If yes, which brand(s)?

Also, I have read positive AND negative reviews about Monkey Wizz and Quick Fix Plus, and TestClear (dehydrated human urine). I have no idea which one to use!
Also, some people said using synthetic urine is all about practice, but I can't afford to buy 3 $50 sets of synthetic urine to practice with!

PLEASE HELP!!!
