Spoon test ?

my little brother just told me that my mom found out he smoked from a spoon test. is this a real test or did my mom just use reverse psychology?, she said that she took a spoon he used to her work(a hospital) and tested it and found traces of marijuana on it

It would have to be a saliva test (which aren't very reliable from what I hear), but odds are she is just BSing him.

Is your mom hot?

Sorry.......
