A marijuana high can enhance core human mental abilities. It can help you to focus, to remember, to see new patterns, to imagine, to be creative, to introspect, to empathically understand others, and to come to deep insights. If you don’t find this amazing you have lost your sense of wonder. Which, by the way, is something a high can bring back, too.
There's no room for hate and violence in this world. We must learn to be more kind, compassionate, empathetic, and sympathetic to humanity.
You can't love someone without imaginative sympathy, without beginning to see the world from another point of view. You can't be a good lover, a good artist or a good politician without this capacity (you can get away with it, but that's not what I mean). Show me the tyrants who have been great lovers.
