Luckily my parents arent victims of the propaganda and base there knowlege on weed from there own personal experiences, like sane people, so i smoke in my room, with no worries.

Im the irresponsible type so im going to tell you to keep smoking, i mean what if the test does come back positive? she wont turn you over to the cops and if you keep your grades up just ask her what the problem is, or inform her of the benefits and harmlessness of cannabis. But lifes to short not to be responsible so i say smoke discretely.
