Prescription for Adderall with out parental knowledge?

I am a 21 year old college student, still on my parents insurance.

I was wondering if it would be possible for me to get a prescription for adderall with out my parents finding out. I have used adderall to study for tests and it make a huge difference.

I do not think my parents would be on board with the idea though. Even bringing it up would incite fears of me being addicted to drugs in my very conservative mother.

Please, only helpful comments. I do not need a lecture as to why I should be able to study with out drugs.
