(I am not a doctor) Lamictal will only affect a drug test if it's included in the list of drugs they're looking for. It is of course a "controlled substance" and if you aren't prescribed it, you shouldn't be taking it.
no but some foods can
No doz is caffeine
Yes
Some antidiarrheal drugs can affect the results of drug tests. One example is loperamide, which is the active ingredient in Imodium. The reason that it can affect a drug test is that it is an opioid.
I know that marijauna and methamphetamines will not cause you to fail a drug test. However I have heard that Ectasy may affect the results of a drug test.
no. when you take a drug test anyway you must always state if you are taking any medication.
Having your period should not affect the results of a drug test. Menstruation does not impact the chemical composition of your urine or blood in a way that would alter drug test results.
yes
No.
There are a lot of factors which can affect passing a drug test. First what kind of drug test you are going to take, are you a heavy user, what drug you use, what is your body type etc...
No, B12 vitamins do not help pass a drug test. Drug tests are designed to detect specific substances in the body, and taking B12 vitamins will not affect the results of the test. It is best to avoid drugs altogether if you know you will be taking a drug test.
