Think about all those who grow and deal, i.e. the suppliers that are necessary for the market. Felony convictions and jail time can really hurt someone's life.

Think about the uses of cannabis (hemp) for textiles, paper and seeds.

Think about the gangs and destruction of public land.

Think about the people that get ripped off or robbed.

And the quality would not be worse. It would be a lot cheaper too. If people want high quality then there will be a market for it.
