Interesting how many comments here say that a big issue with pot is that it makes you "unmotivated". I suppose this is a problem for people who are in tough spots in life and are using pot as a form of escapism. But besides this, what exactly do we need to be motivated for? Grinding away harder at a corporate job? At a certain level "motivation" can be counterproductive and you might be better off slowing down and appreciating your life as it exists now - something that weed can help with in my experience.
