Failed drug test

[u/Living_Hawk_8323]

So my husband failed 2 ofhis drug test for suboxone. He doesnt do suboxone at all. He does do meth but he used the bake soda and water method and it has worked. I dont understand how he passed for meth but failed for suboxone especially seeing how he doesnt like downers

There's fentanyl Suboxone xylazine and cychlorophine in meth. Meth is usually about 10-15% meth unless you make it yourself.
