Hmm... imperial, that would include all forms of entertainment as well as food, no?
Especially candy... mmm... donuts...
Salvia appears to be safe (speaking from experience), and I've heard some good trip reports, but I never really got off on it. Apparently it doesn't keep well, so the stuff they sell at headshops is stale. It tastes like burnt incense when you smoke it... nasty. Also, if you don't burn it right the first time, you get ZERO effects from burning more afterwards. If you're interested, grow your own. There should be plenty of info on erowid or somewhere about how to ingest it.
If that is too much trouble... (IMHO) just go buy a sack of the good herb, and burn it ceremoniously. That *always* works for me. Tastes a lot better, too. Lasts longer...
Oh, why is it legal? Because nobody is standing on the street selling it, taking good money away from hard-working tobacco and beer companies, that's why!
