salvia divinorum 5x extract questions

[brokenzoobies]

I am a first time salvia user and have just ordered what the site sais is "pure 5x extract added back onto fresh-dried Oaxacan Salvia Divinorum leaves". I have a very small glass pipe and your average bic lighter. I'm thinking of smoking 100 mg for my first try. If i draw the lighter into the pipe suck in hard and hold it in for 20 seconds and repeat should i be fine? i have read that you need a butane lighter and a water pipe but have also read that this is only true for the leaves and not the extract...can someone please clear this up for me?
