How did people make rope out of marjuana?

Marijuana is a form of hemp. People have been making rope from the hemp plant from before the days of recorded history. You take three strands of the stems of the hemp plant and stretch them out. You put the three stems together and put an iron ring around them.You attach each one to the middle of a wheel. Then you spin all three wheels at the same speed in the same direction and it creates a hemp rope. You will need to move the iron ring in the process. The hemp in the marijuana stem is the same as any other hemp.
