I've been thinking of something lately and was hoping the talent around here could tell me if i'm barking up the wrong tree...
Two words: nicotinic antagonists. A chemical that's capable of fully inhibiting the effects of cigarettes; *not* a replacement or maintenance-patch, but a full-on antagonist that'd make smoking cigarettes wholly unsatisfying (much like naloxone for opiates)
Is there anything that makes that impossible/impractical from a pharm/neurochem perspective? I cannot say i'm too familiar w/ nicotinic receptors adn whatnot, so the idea may be flawed for obvious reasons that i'm just not seeing.
/otherwise, this one is one you, RC developers. Think there's a market for cannabinoids and stims? A pill that crushes cigarettes/nicorette/etc would be fire, and a true public service at that.
