Well I failed my test. I had no notice so all I could do was to take 4 aspirin and drink about 75 oz. of liquid in less than an hours time. I tried to sub but was watched so I had to give my own. And I failed, but I said I used hemp seed oil regularly and they told me to show it to them and they were going to give me a month to retest. They really like me at this job and I swore I would be clean but do I have enough time. I said give me 30 days to get it out of my system. I need to know if 30 days will be long enough for a daily smoker, about 1/4 oz. per week for years. I am 5'7 180 lbs. who has been exercising and losing weight for the last few months. Is there anything else I can do to help? I can't fail again. And I can't sub. Any advice? Thanks.
