Positive Result For Methadone, Could This Be Caused By Benadryl (Page 2) (Top voted first)
Updated
Benadryl absolutely cannot give a false positive for methadone.
Heres why:
Methadone is an opioid (synthetic opiate) and passes the blood-brain barrier, which gives one the sensation of being high.
Now, benadryl (diphenhydramine) is a synthetic antihistamine, which blocks the effects of histamines by binding to special sites on cells called receptors, but its important to note that benadryl does NOT pass the blood-brain barrier.
**Lastly, and most importantly, methadone cannot be detected on ANY store bought 12 panel drug test, and is very, very rarely tested for in commercial and/or government drug tests. Methadone must be specifically tested for to be detected.
Benadryl can sometimes (extremely rare) show a false positive for benzodiazepines on a drug test and taking benadryl isnt accepted as a legitimate excuse for testing positive for any drug.
I hope I answered your question.
Be safe, and be smart!
