Hemp cloth, which comes from the cannabis plant, is increasingly being used for jeans, jackets and skirts. But you can't roll up your shirt and smoke it. Cannabis grown for hemp cloth is planted tightly together, while cannabis intended for recreational or medical use is a different variety which needs to be planted sparsely to synthesise enough THC (tetrahydrogannabinol) to get a high.
Instead, sativa hemp, for cloth, is environmentally-friendly, economical and legal. It can grow to five metres in 100 days without the aid of chemicals.
