So I went to go take a physical for my high school Marine Biology class so I could scuba dive. I went to the physical alone with a permission slip from my parents (you gotta be 19 in iowa to go to the doctor alone). I get in there and the doctor told me to piss in a cup and he wasn't gonna take a blood test, so whatever. I've pissed in the cup before, and i've seen many posts on this forum saying the piss test isnt to test for marijuana, and it never has in the past for me, so I was cool with it. So wake up this morning and my parents wanna talk to me, we sit down and they say the doctor called and said I tested positive for marijuana and amphetamines. I took some adderall and thats what the amphetamines were, but they didnt really ask about it. My parents said just don't drive when i've been smoking and werent really too harsh about it. They never said "DONT smoke pot" they just said "Dont DRIVE after you smoke pot" They grounded me for a week, but my friends can come over, but thats not too bad so whatever. So my question is can the doctor just test for drugs cuz he wants to? Cuz I asked my parents if they requested it and they said no. Im pretty sure they didnt because my dad isnt really a snoopy person and he wont lie to me.
