Is it true that if you drink vinegar before a drug test you will pass it?

Yes, every time you feel like smoking a joint, take a double shot of vinegar instead. If you do this for two months straight, the THC will be in your system in such low levels that most tests will not detect it.

You can even skip the vinegar for those two months you go without smoking dope. There is nothing magical about vinegar. THC is fat-soluble and does not dissolve in vinegar.
