I do not think that the Coca Leafs should be banned and outlawed it is a part of their religion and culture and is not something that someone can just stop doing. You would not expect a Christian to stop practising rituals, or a Muslim, or Catholic or any other religion. It is a part of who they are and you can not just ban a part of someones life. The leaf is not harming their health and does not harm anyone else so they should just be left alone. By allowing a range of religions in an one area you have to be able to accept the different practices that comes with all of them. It is not fair to stop someone else's rituals because your religion does not believe in it.
