In vitro study(beware of the serum!), not supported by in vivo studies
except in extreme concentrations. Have a look at Hampson et al, July 7,
1998, PNAS. More than blocking calcium channels, and in this study the non
psychoactive forms were also very effective. NMDA antagonists can be
dangerous, cannabinoids very well tolerated, and would someone explain to me
why Fried found, as published recently the Canadian Medical Journal, slight
increases in IQ in heavy smokers who ceased smoking and light smokers still
smoking? Also, recent study found that cannabis, rather than its particular
constituents, more protective, possibly because cannabis elements contains
antioxidant functions, as Hampson study revealed. Doctors cannot administer
that which has not been approved. This needs more careful attention, if
cannabis were as neurotoxic as some studies suggest long term potheads
should be dithering idiots after a decade yet a study published some weeks
ago found very minor deficits after long term use. The emerging concensus is
towards the protective side but this does not validate smoking for
neuroprotection because it makes you so dull and most pot smokers are too
scatter brained to think well(exception, the smart ones who can maintain D1
function at a guess) .... . No, I'm not validating cannabis, but given the
weight of evidence and its favourable profile it should be receiving more

Oh and I forgot, cannabinoids inhibit cytokine production, very useful for
protecting brain cells.
