Before you eat that party favor
your tests should provide you with 2 answers:
Does it have what I want?
Sometimes a pill or powder does not contain the substance it was sold as. Select at least ONE test that changes color with the substance you are expecting in your pill or powder.
Does it have any harmful adulterants?
Party favors can be cut with additional psychoactive substances you would never want to put in your body.
Select at least ONE ADDITIONAL test will rule out harmful adulterants.
