What other uses for Cannabis are there?

One of the newest uses of Cannabis is in construction materials. Cannabis can be used in the manufacture of "press board" or "composite board". This involves gluing fibrous Cannabis stalks together under pressure to produce a board which is many times more elastic and durable than hardwood. Because Cannabis produces a long, tough fiber it is the perfect source for press-board. Another interesting application of Cannabis in industry is making plastic. Many plastics can be made from the high-cellulose hemp hurd. Cannabis seed oil has a multitude of uses in products such as varnishes and lubricants.

Using Cannabis to build is by no means a new idea. French archeologists have discovered bridges built with a process that mineralizes hemp stalks into a long-lasting cement. The process involves no synthetic chemicals and produces a material which works as a filler in building construction. Called Isochanvre, it is gaining popularity in France. Isochanvre can be used as drywall, insulates against heat and noise, and is very long lasting.

"Bio-plastics" are not a new idea, either - way back in the 1930's Henry Ford had already made a whole car body out of them - but the processes for making them do need more research and development. Bio-plastics can be made without much pollution. Unfortunately, companies are not likely to explore bio-plastics if they have to either import the raw materials or break the law. (Not to mention compete with the already established petrochemical products).
