It's safe if you are me, I presume. But only cos I haven't dropped dead from anything so far. YMMV 
I wouldn't compare 6-APB with any of the drugs you mention - certainly not Salvia :D - but I guess speed or meph (ick - can't believe I even said that
) would be the closest... but still a million miles away. I think you would find it to be quite unlike any of the drugs you are familiar with and would be best off reading the reports from users (all of 'em - not just mine) in this thread and over in Trip Reports to get some idea of what to expect. MDMA would be the closest drug that it could be compared with really, in my opinion... but of limited use unless you're familiar with that so trip reports are your friend
