other person. Antique blowguns are, however, exempt. In Canada, the blowgun is classified as a prohibited weapon and is defined as any device that "being a tube or pipe designed for the purpose of shooting arrows or darts by the breath". Any imported blowgun must be deactivated by either drilling a hole or by blocking it. In the Republic of Ireland, blowpipes (blow guns) are classified as illegal offensive weapons. In the US State of California, blowguns are illegal. They are also illegal in Massachusetts and the District of Columbia, but are legal elsewhere. There is currently no age requirement for using a blowgun. Poisoned darts Shooting darts with a blowgun is an extremely stealthy, and even lethal, hunting technique if the darts are poisoned with plant extracts or animal secretions. In Guyana, Suriname, French Guiana, some isolated areas in South America, and in the Amazon and Orinoco basins, blowgun hunters impregnate the tips of their darts with curare. The explorer Joseph Gumilla first mentioned the use of this poison. In ancient literature, it's also referred to as uiraêry, uirary, uraré, woorara, and wourali. The Ticuas, an ethnic group from Brazil, Colombia, and Peru, produce a type of curare called Ticuna. This poison acts quickly on the prey, killing birds like the toucan in a matter of three to four minutes and small monkeys in about eight to ten minutes. In the Orinoco basin, the blowgun and curare are used by: the Hoti, who make blowguns that are unique in their components; the Panare, who obtain blowguns from the Hoti; the Huottuja, or Piaroa, who get their blowguns from the Yekuana or Maquiritares; the Maquiritare, who get their curare from the Piaroa; and the Pemones, who also get their blowguns from the Yekuana or Maquiritares, though they make their own curare. In the upper Rio Negro basin, the combination of blowguns and poisoned darts is used by the Curripacos, or Banivas, who make their own blowguns using technology and materials different, in part, from those of the ethnic groups of the Orinoco. They also produce their own curare. Their ancestors, the Waodani, used a match known as kakapa along with the curare to impregnate the darts of their blowpipes. The Piaroa are known for making curare to impregnate the darts of their blowguns. They produce it beginning with extracts of different species of plants from the Strychnos genus- mainly maracure
