Sundance'll see this and chime in if he sees fit. As one of the resident "under-guns" and a remotely qualified spokesperson, however, I'll address this, too.

It's not that legal bud threads aren't allowed, Slip. It's legal-bud-bashing threads. And nearly everytime someone asks the question out of natural and understandable curiosity, some other joker--inevitably one who hasn't actually tried legal buds--steps in and does some bashing. So we end up taking the completely innocently intended threads down to pre-empt further bashing and to honor our advertisers. The disclaimer paragraph we standardly paste in or link to is below.

I just took down a reesurrected old thread that member (thanks, Happiest!) kindly brought to our attention. It not only contained bashing both old and new but also a recommendation from someone to try smoking a substance many of us use as a spice in puddings and pies. Not a spice, if anyone has done even the least little bit of reading, that produces remarkable psychotropic results and not a substance we're in the business of discussing on a site devoted to cannabis.

I recommend that everyone who's interested in the effects of plants, spices and herbs visit the Erowid site and avoid making non-cannabis substance recommendations--or legal-bud-bashing comments--here.
