They cost money and are hard to make. In many cases, they do not work as well, either. Some prescription drugs which marijuana can replace have very bad, even downright dangerous, side-effects. Cannabis medicines are cheap, safe, and easy to make.

Many people think that the drug dronabinol should be used instead of marijuana. Dronabinol is an exact imitation of one of the chemicals found in marijuana, and it may actually work on a lot of the above diseases, but there are some big problems with dronabinol, and most patients who have used both dronabinol and marijuana say that marijuana works better.

The first problem with Dronabinol is that it is even harder to get than marijuana. Many doctors do not like to prescribe dronabinol, and many drug stores do not want to supply it, because a lot of paperwork has to be filed with the DEA. Secondly, dronabinol comes in pills which are virtually useless to anyone who is throwing up, and it is hard to take just the right amount of dronabinol since it cannot be smoked. Finally, because dronabinol is only one of the many chemicals in cannabis, it just does not work for some diseases. Many patients do not like the effects of dronabinol because it does not contain some of the more calming chemicals which are present in marijuana.

Marijuana has thousands of possible uses in medicine. Marijuana (actually cannabis extract) was available as a medicine legally in this country until 1937, and was sold as a nerve tonic - but mankind has been using cannabis medicines much longer than that. Marijuana appears in almost every known book of medicine written by ancient scholars and wise men. It is usually ranked among the top medicines, called "panaceas", a word which means "cure-all". The list of diseases which cannabis can be used for includes: multiple sclerosis, cancer treatment, AIDS (and AIDS treatment), glaucoma, depression, epilepsy, migraine headaches, asthma, pruritis, sclerodoma, severe pain, and dystonia. This list does not even consider the other medicines which can be made out of marijuana - these are just some of the illnesses for which people smoke or eat whole marijuana today.

There are over 60 chemicals in marijuana which may have medical uses. It is relatively easy to extract these into food or beverage, or into some sort of lotion, using butter, fat, oil, or alcohol. One chemical, cannabinol, may be useful to help people who cannot sleep. Another is taken from premature buds and is called cannabidiolic acid. It is a powerful disinfectant. Marijuana dissolved in rubbing alcohol helps people with the skin disease herpes control their sores, and a salve like this was one of the earliest medical uses for cannabis. The leaves were once used in bandages and a relaxing non-psychoactive herbal tea can be made from small cannabis stems.

The most well known use of marijuana today is to control nausea and vomiting. One of the most important things when treating cancer with chemotherapy or when treating AIDS with AZT or Foscavir, being able to eat well, makes the difference between life or death. Patients have found marijuana to be extremely effective in fighting nausea; in fact so many patients use it for this purpose even though it is illegal that they have formed "buyers clubs" to help them find a steady supply. In California, some city governments have decided to look the other way and allow these clubs to operate openly.

Marijuana is also useful for fighting two other very serious and wide-spread disabilities. Glaucoma is the second leading cause of blindness, caused by uncontrollable eye pressure. Marijuana can control the eye pressure and keep glaucoma from causing blindness. Multiple Sclerosis is a disease where the body's immune system attacks nerve cells. Spasms and many other problems result from this. Marijuana not only helps stop these spasms, but it may also keep multiple sclerosis from getting worse.

The pulp (hurd) of the hemp plant can be burned as is or processed into charcoal, methanol, methane, or gasoline. The process for doing this is called destructive distillation, or "pyrolysis". Fuels made out of plants like this are called "biomass" fuels. This charcoal may be burned in today's coal-powered electric generators. Methanol makes a good automobile fuel, in fact it is used in professional automobile races. It may someday replace gasoline.

Hemp may also be used to produce ethanol (grain alcohol). The United States government has developed a way to make this automobile fuel additive from cellulosic biomass. Hemp is an excellent source of high quality cellulosic biomass. One other way to use hemp as fuel is to use the oil from the hemp seed - some diesel engines can run on pure pressed hemp seed oil. However, the oil is more useful for other purposes, even if we could produce and press enough hemp seed to power many millions of cars.

Why hemp fuel is better than petroleum?

Biomass fuels are clean and virtually free from metals and sulfur, so they do not cause nearly as much air pollution as fossil fuels. Even more importantly, burning biomass fuels does not increase the total amount of carbon dioxide in the Earth's atmosphere. When petroleum products are burned, carbon that has been stored underground for millions of years is added to the air; this may contribute to global warming through the "Greenhouse Effect", (a popular theory which says that certain gases will act like a wool blanket over the entire Earth, preventing heat from scaping into space). In order to make biomass fuels, this carbon dioxide has to be taken out of the air to begin with - when they are burned it is just being put back where it started.

Another advantage over fossil fuels is that biomass fuels can be made right here in the United States, instead of buying them from other countries. Instead of paying oil drillers, super-tanker captains, and soldiers to get our fuel to us, we could pay local farmers and delivery drivers instead. Of course, it is possible to chop down trees and use them as biomass. This would not be as beneficial to the environment as using hemp, especially since trees that are cut down for burning are "whole tree harvested". This means the entire tree is ripped up and burned, not just the wood. Since most of the minerals which trees use are in the leaves, this practice could ruin the soil where the trees are grown. In several places in the United States, power companies are starting to do this - burning the trees in order to produce electricity, because that is cheaper than using coal. They should be using hemp, like researchers in Australia started doing a few years ago. (Besides, hemp provides a higher quality and quantity of biomass than trees do).
