Does weed change the way you think?

ive been smoking pretty much every day for about 7 months now & ive noticed my moods have lke changed since then, i have becomed very confused from it and ive noticed it made my train of thought worse and i was wondering does it effect the way you think? because ever since i started smoking ive been thinking alot more about everything and if i quit would it change or is it just how i am?
