The whole "being proud of it" part makes you sound like a proper cunt, mate. Just another way to convince yourself that you're better than someone.

Now replace "smoking to relax" with "working out to relax" or "taking a hot bath to relax" or "listening to music to relax" or "gardening to relax."

Sure, many people smoke pot, but that doesn't mean everyone should. Some people have effects like what you mention.
