Cannabis is used to make hemp rope and is the oldest cultivated nonfood plant.
It was first isolated in 1964. It is distributed unevenly throughout the plant in the resin. The highest concentration is found in the flowering tops, then in the leaves, then in the fibers. This is a sexed plant with both male and female forms. In cultivated plots the male plant is often removed to prevent fertilization of the female plant which increases its THC concentration.
