Congrats on testing negative. Since you have privacy in the bathroom just get some clean urine from a non pot smoking or drug using friend. Have them put their clean urine in a plastic pill bottle with a locking cap (it won't leak.) In the bathroom hold the bottle under hot water to raise the urine temp to body temp and just give them the clean one. They can't tell it's not yours unless you are a man and the urine came from a woman. But they would have to run an addtional expensive test to determine the sex, and that they will not do. Or since your clean stay that way, but if you use, this works. I did this for 5 years while on a methadone detox where I had to radomly drop, until my Dr gave me a 'script for Marinol, VIOLA home free (I live in a non medical marijuana state, yet you can legally become an opiate junkie using methadone. I know 2 people who get over 250 15mg Methadone pills a month plus 225 8mg Diladud, our drug laws are so messed up... Good Luck!!!:smokin:
