you should be fine if you're average weight/height/etc...

i'd suggest investing in a home drug test (available at CVS for $15.00) and testing yourself.

i workout myself on a daily basis and passed a home test in 6 days with a fairly strong line after smoking daily for a good couple months prior.

in terms of dilution, there is a sticky posted that is helpful on the top of the drug testing forum entitled "DILUTION: tips, tricks and guidelines"
