please provide me with any research information pertaining to the
adverse affects of marijuana usage on the prostate gland. 
specifically it's effect as a catalyst of prostatitis, or benign
prostate hypertrophy.  other research (causes, catalysts, effects,
treatments) on the condition would also be helpful, but marijuana
usage should be the main focus.

Greetings!  Putting aside the adverse effects for a moment, I found an
interesting study pertaining to cannibis and its possible help in
prostate cancer.  A study by nutrition researchers at the University
at Buffalo has "provided the first evidence that a minor plant-based
fat called B-sitosterol appears to play a role in inhibiting the
growth of human prostate-cancer cells.  They found that the
phytosterol B-sitoserol, a fat abundant in Cannabis Oils, enhances an
intracellular signaling system that tells cells not to divide. The
study showed a 28 percent inhibition of prostate-cancer cell growth
after being exposed to B-sitoserol for five days in vitro."

The full article concerning the study may be viewed at and proved very interesting

In regard to prostatitis, I found no direct relation to it and
marijuana but I did encounter numerous references to marijuana and
infertility such as this from Cornell University Weill Medical
College, Cornell Institute for Reproductive Medicine:

"Patients with infertility can have some control of their reproductive
function by living healthy lifestyles. Often some “negative”
lifestyles may be contributing to their infertility. Therefore, if
patients live healthy lifestyles, it is possible that there will be
some improvement in their reproductive function. There may not be
conclusive evidence for all these lifestyle recommendations, but
rarely will following these guidelines hurt, and often they may help:
Avoid excessive heat (avoid waterbeds, saunas, hot tubs, etc.). 
Limit coffee to 1 or 2 cups per day. 
Do not smoke. 
Do not use marijuana, cocaine, or other recreational drugs. Marijuana
stays in the testes for over 2 weeks; so even using it once every two
weeks will have a negative effect. ."

In a list of medical conditions treated with cannabis, Tod H.
Mikuriya, M.D. listed prostatitis in the list he compiled.  However,
there was no link to the study itself.

At, there is a user group for discussing the medical use
of  cannabis at the group.  I would suggest you join
the list and pose the your question there.  There were also groups for
prostatitis and benign prostrate hypertrophy.  I included all the
links below.
I did numerous searches using the terms “prostatitis” and “benign
prostate hypertrophy“ coupled with THC, cannabis, tetrahydrocannabinol
and marijuana.  I found nothing stating adverse effects on those
conditions from marijuana use.  To the contrary, marijuana use seemed
to help prostate problems as opposed to causing them.

As for causes of prostatitis, had the following to

On the scientific level, the causes of prostatitis are not completely
understood. There is controversy among the most highly regarded
experts. Keep in mind that any one patient may have more than one
cause operating at the same time. Or, looked at from another point of
view, prostatitis could be several different diseases which present
with the same or similar sets of symptoms in different individuals.
Want some contrasting viewpoints?
Five years of online discussion and a lack of scientific consensus
means there are different viewpoints on almost everything that can be
discussed here. To learn those conflicting points, click on search ,
and enter the terms you are wondering about.
There are three main schools of thought about the causes of
prostatitis. Each of these will soon have a page of its own. Hold your
cursor over the link to see a pop-up telling you the link's status:
Bacterial infection, 
Auto-immune response or disordered immune response, 
Neuromuscular, tension or physical injury problem

Additional possible causes: 
a uric acid disorder, 
prostate stones, 
a urethral stricture, 
a rare tumor, 
prostate cancer, 
benign prostatic hyperplasia (BPH, non-cancerous growth of the
a food allergy, 
a yeast infestation, 
a specific yeast problem from the Genus Candida, 
or a virus. 
If you've had prostatitis for very long and had very many appointments
to try to deal with it, you've heard some of these theories.
Does it matter what is causing it? Will knowing the cause help you get
over it? The answer would be "yes," if only determining the cause were
simple. (See the "Methods " page for a discussion of methods of
treating prostatitis.) Also, unfortunately, even doctors who are sure
of the cause of prostatitis in their patients cannot cure all their
If your prostatitis is caused by bacterial infection, knowing that
should help your doctor treat the infection and make you better.
Unfortunately, many doctors and clinics do only cursory checking for
bacteria. But even doctors who do very careful checking for bacteria,
and indeed find bacteria, cannot always make their patients' symptoms
go away.
Similarly, ruling out bacteria and going on one of the other
hypotheses does not necessarily help either. If you thought or even
knew that your prostatitis is caused by an immune disorder, does that
mean there is a clear route to fixing the problem? Not likely.
There are therapies around for fixing physical problems. There are
people who can teach you relaxation techniques, or
muscle-strengthening techniques, to repair or ameliorate problems with
your pelvic floor musculature. But there is no clear path that works
for everyone.
Why can't doctors fix you up? Well, for one thing, they aren't trained
very well in diagnosing and treating prostatitis. Urologists spend
most of their time studying surgery. If prostatitis were something
that could be fixed by surgery, they'd give it a try. And other
doctors tell patients to "learn to live with it."


The above site has many live links in the text which give more
information on the condition.  It is very comprehensive and should
answer all of your questions, and Cipro offered a good site as well.

I hope this information is of assistance and should you need further
clarification, please ask.

Currently the only study on effects of marijuana on Sperm has shown
only those individuals with a family history of low sperm count, fast
sperm or infertility can be affected by long term usuage of marijuana.

If you do not have a history of this low sperm count, fast sperm or
infertility  in your family there is currently no study showing you
would be affected by marijuana use.
