Hemp (Cannabis sativa) is a recognized papermaking fibre which can be grown in most regions of North America. There are many citizen groups lobbying for the repeal of the Narcotics Act for the growing of fibre-grade hemp. For papermaking purposes, hemp bast fibre is used interchangeably with flax bast fibre. The latter can be readily sourced from oilseed flax cropping. There are over 1 million hectares of oilseed flax grown annually in North America. Both hemp bast fibre and hemp hurds (core) can be used for the manufacture of papermaking pulps. Despite its low lignin content, hemp bast fibre is somewhat difficult to pulp and bleach.
