Well, I'm all for marijuana because it's an essentially harmless drug (medically beneficial for a lot of people, in fact), and it makes everything fascinating and hilarious, makes food taste incredible and makes video games more immersive. Introspection is easy when high, and it doesn't make you belligerent like some people who drink, you never get angry or violent, just euphoric and empathetic. You can experience almost anything on a deeper level.
There have been some studies that say it's been linked to some sort of brain damage ("drop in IQ") from heavy, sustained use from a young age, but they are inconclusive, and I don't do nearly enough for this to apply to me even if it was true.
As for legal aspects... well prohibition is just ineffective. It plain and simply does not work. I'm sure others will go into/have gone into more depth here, so there's no point in me doing so.
