Eh you don't know what you don't know. Plus the detox drink makers tend to make their drinks look more legit by doing thing such as guaranteeing that you'll pass, but what they don't tell you is that they guarantee you'll pass a nicotine screening. They can't legally sell products to pass drug tests for illegal drugs. That's why the company that sold the Whizzinator got shut down, they were advertising that it helped pass drug tests such as the ones given by the DOT to truck drivers.
