This is 100% correct. I have my prescription, for oils, as I had skin cancer removed and there is evidence the ingesting the oils can inhibit further growth internally.
I have never smoked anything.
Many people want to have it legal for preventative health, much like vitamins. They can't get their prescription because there is nothing medically wrong.
Others want to use it in cooking (goodies for a party) because they don't want to smoke it.
