I would get numerous home-testing kits/strips on-line - the ones from Wal-mart or other drug stores are at least $20 and you only get 1.
Read, read, read - this site has tons of information about your exact question. It seems that it may not take 30 days to get out of your system since you don't smoke consistently, but that's why the home-tests could help give you peace of mind. There are detoxifying teas at health food stores, others have mentioned drinking cranberry juice, water and vitamins - read up and find what's best for you.
Good luck and don't get injured!
