Mascar22,

Hey man don't sweat it, just relax and read deeper into some of these threads. I recently subbed and found all the information I needed right here, on this one forum. Anything other than subbing is extremely unreliable as you already know. Unless it's been over 3 months since you last smoked I'd say you would be good with diluting, anything less...SUB. Besides subbing is cheaper, easier and more reliable. Crotch your QF, walk in, pour it in the cup and walk out...for simple pre-employment screenings it's a garunteed pass if you get the temperature right. Happy trails brotha, and let us know how it went!
