Meh... I prefer to think that people are being deliberately obtuse than to believe that they're really that ignorant. There's no reason to be that ill informed if you have an internet connection other than a deliberate effort not to learn.

Or even more direct evidence that it can be good for normal brain tissue: http://www.jneurosci.org/cgi/content/abstract/21/17/6475
Quote:
Excitotoxicity is a paradigm used to explain the biochemical events in both acute neuronal damage and in slowly progressive, neurodegenerative diseases. Here, we show in a longitudinal magnetic resonance imaging study that Delta 9-tetrahydrocannabinol (Delta 9-THC), the main active compound in marijuana, reduces neuronal injury in neonatal rats injected intracerebrally with the Na+/K+-ATPase inhibitor ouabain to elicit excitotoxicity. In the acute phase Delta 9-THC reduced the volume of cytotoxic edema by 22%. After 7 d, 36% less neuronal damage was observed in treated rats compared with control animals. Coadministration of the CB1 cannabinoid receptor antagonist SR141716 prevented the neuroprotective actions of Delta 9-THC, indicating that Delta 9-THC afforded protection to neurons via the CB1 receptor. In Delta 9-THC-treated rats the volume of astrogliotic tissue was 36% smaller. The CB1 receptor antagonist did not block this effect. These results provide evidence that the cannabinoid system can serve to protect the brain against neurodegeneration.
(tl;dr version in bold)
And what really grinds my gears is that this paper was published just over nine years ago and we're still having this conversation.

mark my words its not going to happen.... it would cause a decreease in alcohol drinking and other hard drugs. Why would the government want that?
Because if we had a less brain damaged electorate we might actually be able to comprehend policies more complex than "We believe the other side's leader is a SCARY SECRETE MUSLIM!"
