Can Benadryl cause a false positive for meth?

Thanks. You too.

I made a mistake , I was referring to "Benadryl Allergy And Cold" which is my original answer.

Benadryl only contains:

Diphenhydramine , which Can Cause False Positive For Phencyclidine also known as angel dust.

Once again I apologize.

You are very welcome.

Thanks for your correction. It makes a huge difference.

You are welcome indeed.

All the best ,
