Marijuana or Hashish
(Cannabis sativa) is a native plant
of Asia and Middle East. Some cultures regard it as a
gift
from Gods. According to the Hindu legend, the plant was
brought by Lord Siva from the Himalaya for people's
enjoyment. Smoking the leaves and seeds relieves nausea,
moderate chronic pain, increases appetite and reduces
muscle
spasms. This is due to the psychoactive constituents
tetarhydrocannbinol (THC) which is also addictive. Smoking
cannabis also reduces the intraocular pressure through
vasodilation and hence the red eyes in chronic users.
Topical
application of THC does not appear to have significant
effect
in lowering the intraocular pressure. Until further study,
daily
consumption of cannabis is not recommended as the treatment
of choice for glaucoma. |
