Apart from the pleasant effects that it can have on your mood and state of mind, cannabis has a thousand uses you probably never heard of. During Holland's Golden Age, Dutch East India Company ships made their ropes and sails from hemp, while today hemp fibre is still one of the most durable and easy to use materials available for making clothing. The Hash, Marihuana & Hemp Museum displays the history of industrial hemp in its gallery, while its main collection consists of items related to the history of cannabis, the culture that surrounds it and its medicinal benefits. Ancient hash pipes, 17th-century paintings of medieval Dutchmen getting high, cinema posters of Cheech and Chong, a guitar made of hemp and hundreds of other unusual items make this a fascinating place to visit. A small shop selling gifts and cannabis seeds is also attached to the museum.
