HI MARIJANE, exctract is not just groun up salvia, it's usualy leaf soaked in alcohol contianing salvornium A. washed out from LOTS of salvia leaves, anyway the first time you do salvia it usual dosen't do much but after the third forth time you can tell how much harder it hits you, then is the time to try exctract! or at least smoke alot of deacent leaf realy fast..the way i perfer to smoke leaf is in a small bong with a larg bowl, pack about 1-1.5 grams of leaf, hit it hard with the lighter on it the whole time, and hold in your hit for as long as posible. to get rid of the nasty taste when smoking try rolling some crushed up leafes in you stem resin and do this till it's a gooey green/black messy glob, this glog will smoke much nicer, even cut it up and put it on top of a striat bowls of salvia, but if you get exctract and you wana smoke it (thats the way to go)just pack a phatty bowl of weed and leave room to fill the bowl with your extcract and do so, then toke up and sit down
