The Cannabis icon, with a number next to it, at the bottom of each post are the rewards for a post.
While a post is active, it shows the rewards a post has received already. After 7 days posts are paid out and the balance can be redeemed in your wallet. You can see the status of a post when you click on the little arrow at the right of the rewards.
When a post has been paid out already, the dropdown shows how the rewards were distributed between author and curators. By default rewards are split 50/50 between creator and the pool of curators.
