Damn, is that why I'm so stupid? I get high and read myself bedtime stories all the time, usually improv.

dont know, but if thats true then it proves that losing brain cells are nothing anyway, think how many people smoke cigs..Quote:

lol, come on potsmokey, think about it. why would smoking before bed make you lose any more braincells than smoking any other time? it's just bollocks mate, don't worry....
pot helps me sleep. lately i havent been smokin and i cant sleep at nite but i am going to get high over the weekend and it always helps me sleep
rule of thumb: if it sounds too impossible or stupid to be true, then it probably is. especially when dealing with drugs and authority figures.
this is the wisdom you should listen toQuote:

Two new scientific studies have failed to find evidence
of brain damage in monkeys exposed to marijuana, undercutting
claims that marijuana causes brain damage in humans.
The studies were conducted by two independent
research groups. The first, conducted by Dr. William Slikker,
Jr. and others at the National Center for Toxicological Research
in Arkansas examined some 64 rhesus monkeys, half of which
were exposed to daily or weekly doses of marijuana smoke for
a year. The other, by Gordon T. Pryor and Charles Rebert at SRI
International in Menlo Park, California, which is still
unpublished, looked at over 30 rhesus monkeys that had inhaled
marijuana one to three times a day over periods of 6 to 12
months. Neither study found evidence of structural or
neurochemical changes in the brains of the monkeys when
examined a few months after cessation of smoking.
The new results cast doubt on earlier studies
purporting to show brain damage in animals. The most famous
of these was a study by Dr. Robert Heath, who claimed to find
brain damage in three monkeys heavily exposed to cannabis.
Heath's results failed to win general acceptance in the
scientific community because of the small number of subjects,
questionable controls, and heavy doses.
Subsequent rat experiments by Dr. Slikker and others
reported persistent structural changes in the brain cells of
rats chronically exposed to THC. The studies did not show that
pot kills brain cells, as alleged by some pot critics, but they
did show degeneration of the nerve connections between brain
cells in the hippocampus, where THC is known to be active.
Although scientists have regarded the animal evidence
as inconclusive, some critics have cited it as proof that pot
causes brain damage in humans. Thus Andrew Mecca, the
director of California Department of Alcohol and Drug Abuse,
recently stated on the Ron Reagan, Jr. talk show (Sep. 2, 1991)
that marijuana "leaves a black protein substance in the
synaptic cleft" of brain cells, a claim apparently based on
Heath's monkeys. When asked by a NORML member for his
evidence, Mecca sent a list of three references, none of which
turned out to have anything to do with brain damage.
Although the new monkey studies found no physical
brain damage, they did observe behavioral changes from
marijuana. Slikker's group found that monkeys exposed once a
day to the human equivalent of four or five joints showed
persistent effects throughout the day. Slikker says that the
effects faded gradually after they were taken off marijuana,
and were not detectable seven months later, when they were
sacrificed. Autopsies did reveal lingering chemical changes in
the immune cells in the lungs of monkeys that had inhaled THC.
However, Slikker's group concluded that experimental exposure
to marijuana smoke "does not compromise the general health of
the rhesus monkey."

yeh zactly it wouldnt make a difference when you do it. i guess maybe psychologically but definitely not physically.
