I smoked Marijuana 3 weeks ago, just a couple puffs, then then smoked 2 days ago a couple of puffs. Today, I go to work, and was given a paper to go to the lab to be drug tested, as I am a new employee (2 weeks working here). I was out of a job for a yr, and finally found one! I used to smoke all the time, but quit all together. My friend smokes, and offered me some, and I got tempted.:(..I ran to the store and bought 'Champ detox', followed instructions, and went to lab after 2 hrs of drinking it. I am so worried, please has anyone ever used this detox and has it worked? Also, no lectured please.
