Medical Marijuana

By Castulo Zane


Marijuana has many names: cannabis, cannabis indica, cannabis sativa, marihuana, hemp, even cannabis American us but they are all the same plant. Marijuana is used for many different purposes in many different areas.

The use of marijuana has a very long history, stretching back thousands of years. Perceptions of it differ from beneficial to evil. Modern Western medicine is learning about medical uses of marijuana, and sometimes re-learning.

In Eastern medicine, in contrast, marijuana is one of the basic herbs. With the amount of marijuana grown and consumed in the west, and it's growing acceptance, we can look forward to more medical developments as time goes by.

At this time the uses of medical marijuana are still being developed Trials and experiments are constantly occurring Novel methods of cooking with herb, and other ways to ingest the plant are being pioneered.You can split the marijuana world down the middle into indica and sativa.

These two types can be further divided into all sorts of sub-strains Breeders have further multiplied these by selective breeding The result is thousands and thousands of strains and names

Each is genetically different and each has, to some degree, unique characteristics Indicas grow faster overall They can be traced to Africa, Central Asia and the sub-continent Indicas are good for hash, and these areas are traditionally known as hash producers.

With wide, dark green leaves, indicas are shorter and denser than sativas They take about two months to mature once they begin to flower They get big stinky blooms They are good for medicine because of their pain blocking qualities It grows well indoors and it's shape and size make it easier to cultivate as well.

Sativas are long and skinny compared to indicas They don't grow well inside, and while they grow well outside in southern locations they don't thrive in northern latitudes Sativas come from Mexico, Vietnam, Thailand, Colombia and places like that

These are the giant plants that you can see on pictures growing well over 12 feet high. Long, skinny (both in plant size and leaf size) they tend to be lighter green than indicas. They also take longer to mature once budding starts (2-4 months). Sativas account for the paranoia that some people attribute to marijuana, and can cause an irregular heartbeat. Their use in medicinal marijuana is, as a result, more problematic.

That doesn't mean sativas don't have medical uses There are many types of both sativas and indicas They can be selectively bred with each other That creates new combinations of effects - some are enhanced and other diminished.

Breeders try to do exactly that -develop new strains with desirable effects They try to develop what users need and desire This has created more crosses and hybrids than pure strains The results are indica/sativa hybrds, with the predominant strain being the first named in the combination

A sativa hybrid is predominantly sativa, but with some indica characteristics. Indica hybrids have the opposite proportions. Sativa hybrids that have reduced paranoia effects can still have motivational effects, and so become useful, even if they aren't good pain blockers. They are good for anti-depression and for appetite stimulation. Indica hybrids dominate medical marijuana, however, and are good pain blockers. An indica hybrid was the strain I first grew hydroponically - Northern Lights (I've loved it ever since!)
