Prestigious Journal Links Marijuana to Psychotic Disorders
Posted: 01-26-08 22:39pm

The Lancet Journal published a study in
2007 definitely linking psychosis later on
in life with earlier Marijuana use.
Lancet. 2007 Jul 28;370(9584):319-28.
Cannabis use and risk of psychotic or
affective mental health outcomes: a
systematic review.
Moore TH, Zammit S, Lingford-Hughes A,
Barnes TR, Jones PB, Burke M, Lewis G.
BACKGROUND: Whether cannabis can cause
psychotic or affective symptoms that
persist beyond transient intoxication is
unclear. We systematically reviewed the
evidence pertaining to cannabis use and
occurrence of psychotic or affective
mental health outcomes. METHODS: We
searched Medline, Embase, CINAHL,
PsycINFO,
ISI Web of Knowledge, ISI Proceedings,
ZETOC, BIOSIS, LILACS, and MEDCARIB from
their inception to September, 2006,
searched reference lists of studies
selected
for inclusion, and contacted experts.
Studies were included if longitudinal and
population based. 35 studies from 4804
references were included. Data extraction
and quality assessment were done
independently and in duplicate. FINDINGS:
There
was an increased risk of any psychotic
outcome in individuals who had ever used
cannabis (pooled adjusted odds ratio=1.41,
95% CI 1.20-1.65). Findings were
consistent with a dose-response effect,
with greater risk in people who used
cannabis most frequently (2.09,
1.54-2.84). Results of analyses restricted
to
studies of more clinically relevant
psychotic disorders were similar.
INTERPRETATION: The evidence
is consistent with the view that cannabis
increases risk of psychotic outcomes
independently of confounding and transient
intoxication effects. We conclude that
there is now
sufficient evidence to warn young people
that using cannabis could increase their
risk of developing a psychotic illness
later in life.

Same goes for alcohol and many if not most
prescription drugs. Abuse of anything is
deadly...you can eat your self to
death...drink your self to death, with
water! So should water be illegal? Its
called control and moderation...a little
common since goes a long long way!

Most prescription drugs do not cause
people to become psychotic....weed does.
Most people using pot for fun couldn't
care less about moderation. Those using
it for medical use have no idea how much
of the drug they are actually getting so
they can't gauge moderation

The important thing to remember about that
study and studies like it is the inclusion
of a predisposition towards mental illness
and that mj use before full brain
development (at around 23) may accelerate
the onset of mental illness. I posted
another study on here somewhere with more
detail.

Not so...I am not psychotic or mentally
ill, can carry on a conversation without
getting all angry and judgmental. Just
because it isn't right for you doesn't
make it wrong. Live and let live...its all
gonna be OK...for every study showing how
horrific it is there is another study
debunking that story so lets just agree to
disagree. Peace...

There is no anger or judgement in quoting
facts, although it is easy to see how some
could incorrectly come to those
conclusions.

What everyone like you forgets is that the
use of ANY drug in an inappropriate way
before full brain development can lead to
mental illnesses. It's dumb to make
marijuana a scape-goat or to somehow imply
it is different.

Can you support such a statement with
facts? ANY drug? Really!!!! That
would come as quite a suprise to most
pediatricians and obstetricians in
America!!!

ABUSE of any drug. Not just USE. ABUSE.

ANY drug being abused causes mental
illness if used before full brain
development? I would love to see the
facts....please indulge me with your
medical references on such a sweeping
statement.

Eiri, its like talking to a brick wall. He
is algonsdoc's friend so I am done with
him. He has commented to all her posts
positively and all mine negatively so
there ya go...they are messing with me so
I am gonna take my marbles and go home...
And by the way, ABUSE is not the same as
USE, just like Eiri stated...

Let's pick something mundane like Asprin.
What drug would you like to research? I
bet the abuse of asprin in a young
child/teen into the adult years could have
an affect on the brain - not to mention
the rest of their body.

If abuse of any drug leads to mental
illness prior to full brain development,
would it be possible to demonstrate this
with say....phenergan? This drug is
commonly used in pediatric patients and
sometimes overused, but I can't find
anything about it causing mental illness.
The brain doesn't stop developing until
well after birth...
Phenergan is also used during pregnancy
during the brain development of the fetus.
Is there any evidence this causes mental
illness?

Marijuana is a drug that is used over an
extended period of time, and the brain
doesn't stop developing until young
adulthood to my knowledge, a heck of a
long time after birth.
And to be honest, before we get to far
into this cowpile, what I meant by "drug"
was extacy, anti-psychotics, etc. Powerful
mind-altering drugs, both legal and
non-legal. I don't know what school of
drugs to label them as, but "any mind
altering drug, both legal and non legal,
when abused, can potentially cause the
development of a mental illness".

Certainly illegal drugs can do this. But
what about narcotics? Is there any
evidence these cause mental illness when
used before brain development? They
certainly are mind altering just as is
phenergan. My point is that when one
speaks in broad sweeping generalizations
in order to make their point, they are
usually incorrect. A more accurate
statement would be that specific illicit
and licit drugs, whether used
appropriately or not, may in some cases
cause certain types of mental illness.

It still proves my point. Marijuana isn't
the only thing on the planet that does
this; so why is it the scapegoat?

Marijuana should stand on its own merits
as a medical drug, and if the evidence
exists that the harm outweighs the good,
then it would go the way of hundreds of
other drugs in development by
pharmaceutical companies every year.
Unfortunately, it simultaneously exists as
a drug of abuse used solely for
recreational purposes. If medical
marijuana were legalized in a form that
did not cause additional harm (not smoking
it), then I think many people that now
oppose its legalization would become
strong proponents. But it is the
incessant cries of the drug culture to
legalize all drugs including unrestricted
use of marijuana for purposes of getting
high that are troubling to many. The two
messages somehow become intermingled on
forum discussion groups and in front of
congress and government regulators, who
quickly back away from the very hot issue
that is political poison. We definitely
need more research into use of marijuana
as a safely administered drug for medical
use. It will take a change in political
will to permit that to happen....perhaps
the winds of change are blowing in that
direction.
