I smoked weed for 5 months, and i have a job interview/ drug test in a week. But its a saliva test, and i read numerous places weed leaves your saliva in 13+ hours. Please help , idont need no one critisize n say you shouldent smoke in 1st place, someone with personal experiences help me or even if you knoww your facts. I eat healthy and drank like 7 cups of cranberry juice in 2 days. What can i do to make sure i will pass the test or anything i should eat. i hear lemon juice cleans your system.
