I Have My Friend's Drug Test Results That His Aunt

I have my friend's drug test results that his aunt gave him. This report shows the levels of drugs in his system. Would you please be able to tell me if a certain level is high or low for a drug? I am unfamiliar with these narcotics. His aunt has his child, while his grandmother and myself are helping him. We want to know about the usage amounts of these drugs. Will you help me please?
