However, there are several reasons to think that when the prohibitions against its use are eliminated, the hemp plant will also be grown commercially in the U.S. Cannabis fiber is not only the longest and one of the strongest in the plant kingdom, but depending on the variety, methods of cultivation, curing and processing the fiber can be used for anything from ship rope to the finest linen-like material. Virtually no scientific experimentation has been done on modifying the fiber for various uses. Yet in countries where its cultivation is permitted, including France, Italy, and Yugoslavia, it is one of the most profitable crops grown. It would be much more profitable to use cannabis rather than softwood for by-products. Since cannabis takes only one season to grow, farmers could better adjust plans according to market conditions.

Cannabis seed can be used as a high protein animal feed and also for its oil, which has many industrial uses. A high protein animal feed can be made from the mash after it is pressed for its oil. Cannabis is still intimately involved in a symbiotic relationship with humans. This special relationship will help both species evolve and will continue to alter both of their destinies. The most important lactor in producing high yielding potent marijuana is the plant's genes.
