From the comments:
The prohibition of puffer fish does not work. All it does is hand the trade of puffer fish to criminal dolphin gangs who use the money to finance other forms of crime e.g. fish stealing. The sale of puffer fish should be decriminalised and the taxes should be used to benefit all dolphins. There's no evidence to suggest that decriminalisation will lead to increased puffer fish usage and studies have shown it to be much less harmful than other dolphin drugs. Oceans where they've already been decriminalised have lower rates of usage than ones where it's still illegal.
Says it all
