Nah...those type things don't work, the only thing that works for removing methamphetamine and other drugs from your system is not doing them to begin with.
Does vinegar clean your system from methamphetamine?
Vinegar does not have any effect on removing methamphetamine from the human body. This is simply a myth that people hope is true when they've got a drug test coming up and have been taking meth.
Another vinegar technique
Some people have been so desperate to pass a drug test that they've tried to add vinegar directly to their urine sample. The theory is that the vinegar alters the pH of the sample enough that it will pass the test.
Whether this works or not is questionable. Drug tests are highly sophisticated and are set up to ensure that people can't easily cheat the system.
Another thing to note about this method is that many drug tests require a member of staff to accompany the test subject when they're providing their urine sample. This is so the subject doesn't have an opportunity to mess with the sample as described in the above method.
As mentioned earlier, the only surefire way to pass a drug test is to not take drugs at all. Cheating on a drug test could lead to serious consequences.
