does it permanently make u passive? my teacher says marijuana makes you passive, and even though it's good for u, u won't be as competitive, aggressive, or ambitious.

plz tell me this is a thing that wears off, i think it is because i tend to become a more aggressive/angry person after 20-25 days of not smoking. I guess u can't scientifically prove whether or not somebody is passive... i'll be satisfied with opinions.
