I knew three pot smokers who died of cancer. Bamboo is far more versatile than hemp and there are literally thousands of products made from it that are not simply "dietary supplements" or ointments. Do a search of bamboo products vs hemp products and you will discover how few uses hemp actually has. Hemp is also legal in many countries around the world yet they are not producing wonder materials with it and getting rich. It's a shitty material that makes other shitty materials.
