Do the GNC detox drinks work?

They worked for me, but I also stopped smoking for 9 days before the test. So was it abstinence, or the drink, or both? I don't know. It's worth a try, especially if you cannot postpone the test until you are clean. But obviously, the smart thing to do is to abstain from marijuana for as long as possible before the test.

The product I used was called Herbal Clean, but I didn't buy it at GNC. It was a non-chain store in Hell's Kitchen, New York City.

I just told the salesperson, "I have a drug test, I smoke marijuana, do you have any products for that?" and he went and got it for me. But I was reading a blog on some website, and a person said that he went into GNC for one of those drinks, and as soon as he said the words "drug test" the salesperson said she couldn't help because what he was asking for was illegal.

So, just in case you run into a salesperson like that, who is totally uncool, don't mention anything about drug tests. Just say, "I need something to cleanse my system, do you have any Herbal Clean?"
