That is fu*ing weird but if you think about it, it doesn't sound so crazy.
Swim notices that when he attends class stoned he feels tired and don't want to work but he is more focused and less nervous and hyperactive.
Also swim has noticed that studying on pot sometimes helps one calm down a bit and that results in more concentration and definitely helps avoid exams anxiety and fear
But the most important thing: Swim likes very much to smoke before a trip cause he feels very comfortable driving high (not wasted). He feels very relaxed but at the same time focused and confident. He doesn't think pot in small amounts impairs his driving skills whatsover. It actually sharpens some abilities and makes him much less irritable.
