i'm 6'1" 240 lbs and a heavy smoker. new job will be giving me a pre-employment non- dot drug screen. i havent smoked in tha last 9 days. ive taken court ordered drug screening before(10 years ago). at that time i used XXTRA Clean. when i followed the directions it worked for me. once again that was 10 years ago. ive read somewhere recently that it doesnt work any more. even knowing that the drug screening is coming, just not enuff time to naturally detox. i was thinking of using a detox kit until i read that there may be a problem with dilution. im pretty sure im going to a lab where they're gonna test the unrine. what is my best option. need help ASAP
