I have done salvia many times and has worked for me everytime I do it. I have smoked different strengths of it from 5x to 20x the best way to smoke it is with a smaller bong like 2 foot is usually a good size, then take a torch lighter and light that shit up, take the biggest hit you can try not to cough at all and hold it for as long as you can. You should start to feel it coming on as soon as you blow out your first hit. You can either finish the bowl as fast as you can or just let it be, w/e you do put the bong down though cause salvia can get pretty intense sometimes and you dont want to accidently drop your piece Happy Tripping
