How often to keep metabolites low?

So if from being clean I smoked .3 of headies once a week, would i be able to be clean most of the time. I live a very active lifestyle and work outside in the heat all day(40 hours a week), and then lift (5-6 hours a week), and drink a lot of water. I think I should be alright especially since if I ever did get a random drug test I could drink a shitload of water, dilute it, and then buy myself some extra time. I have some fat on me, but with this job I should be 15%bf or less in no time.

What do the pros think of this? I may take to carrying synthetic urine on me.

BTW odds of a test are low, but there.

 

i'd say you're alright.. but dont quote me on it..

 

that's what I figured

 

you should be ok. water and excersise is key

 

one word... Whizzinator. google it, it owns.

 

yeah you should be fine i believe. last school year i was involved in football, had a weightlifting class lifting about 6 hours a week. i got piss tested and passed, and i had been smokin like every other day
