Career Threat

In the next two weeks, there is a great chance I may have to take a drug test: urine and unsuprivised. The job is teaching in a local school system. So, I really don't want to screw this up. This past year, I have been smoking 3 times a week (3-4 bowls). I am willing to quit for the time being.
I visited a local head shop yesterday to discuss my different options. One product that interested me, was a 6 day plan that would permanently cleanse my system of THC. I really would rather not take the job if there isn't a 100% guarantee.
Does anyone know if products like these really work? Should I take a risk? Experts, please help. =)
Any comments would be greatly appreciated.

All detox products work! You have to follow all directions on the product and you will pass. go to www.passmydrugtestnow.com and check out the products. You say that you have a urine test and nobody watching a drink or the sub solution will work for you. wish you luck.

well you said 2 weeks. The cleaners do work. I used certo.
good luck.

If this drug test could have long lasting negative effects, do this. Quit smoking, work up an intense sweat 2x daily. Take niacin, It will make you itch and turn red if it is working. Drink six gallons of water daily. Then buy a at home drug test. Take several on different days to know you will pass.
