I recently was offered a verbal offer for a big company, basically my dream job. The company before giving me the actual paper work in my email requested a background check and drug screen. When the company first called me I dropped all uses of marijuana. I was daily smoker and would use every night to sleep or enjoy the night better. Of course with my luck I did very well in the interview which was scheduled a week after I received the call. When I was done with the interview the people interviewing me said it would take about 2-3 weeks for a call. Not even 4 days later I get the call for the verbal offer, at this point I am 11 days clean. I knew I had to act fast so I started detoxing and cleansing myself. I tried to prolong the test as much as possible, but the company couldn't wait anymore. 18 days later I had 24hrs to attend the drug screen. I tried to prepare myself as best as possible, I wanted to be honorable and not take any synthetic pee or anyone else's in that manner. I tried different detoxes and nothing was working(multiple at home drug test). I finally decided to go with a masking detox to hide the thc in my system. Not the greatest idea, but had no other choice. What I did the morning before was test myself with a CVS at home drug test, and surprisingly came out negative. Although I was still cleansing the second line was very faint. As soon as I saw it was negative I tried to hold my urine till the exam was finished. I ended up doing a second at home drug test 8 hours after the exam and same type of result except the second negative line was not as visible but was there.
My question is, if the company finds any trace of thc in my drug screen and I get disqualified for this reason am I able to request a retest in any way or should I kiss my chances goodbye?
