If you went to a plant nursery in most countries and bought some cannabis seeds probably both you and the shop keeper would have a few problems with the law but not in Amsterdam. The lovely flower and garden shops along the canals sell some of the most beautiful flowers and also cannabis seeds and plants. Growing and the smoking of cannibals for personal use in Amsterdam is quiet legal and there are many cafes and coffee shops around the city where you are quiet welcome to light up and enjoy without the fear of prosecution. It might explain why the Dutch wear clogs?
