The ones on ebay are just as good as the ones you buy at a drug store, just a hell of a lot cheaper.

It happens. If you have slow metabolism, usually because of age and some extra weight it can take a long time to burn off the fat cells to rid yourself of the thc metabolites.
Excersise, high fiber diet and time is all you can do.
The only other option will be subbing.

Today is day 90 since I stopped smoking and I tested myself using one of the test strips that I bought on ebay and I'm still positive!! I've been smoking on and off since the late 60's (mostly on) but come on...90 days? WTF? Rating: 5
