Will a single toke of marijuana be enough to fail a drug test?

Question

I am in the process of quitting smoking both ciggarettes and marijuana all together. I've went from smoking a pack of ciggarettes every 2 days to about 1 cigarrette every 2 days. I went from about 1/10th ounce a day of marijuana to maybe 1 gram every 2 weeks. My question is: Will 1 toke of marijuana be enough to fail a drug test assuming you have not smoked regularly? Yes I realise it's different for different people depending on body fat etc. but I just want a rough estimate.
