if you want it to work, use a glass bong.
salvia can be a very potent hallucinogenic.
i wouldn't smoke anything stronger than 10x until you've experienced a full blown high with that.
i've smoked it approximately ten separate times. the first handful i didn't really feel any effects. the key thing to remember is its a very fragile substance-meaning, the same dosage can do nothing under one circumstance, and take you to a parallel universe in different circumstances.
i've had friends (all experienced psychonauts) smoke 10x extract and react completely differently. some didn't feel a thing. one buddy simply fell to his knees for five seconds before standing up completely fine. another had the most intense trip of his life (above and beyond acid trips,etc).
i've found to get the effects, it helps to do the following.
1. use a glass bong (preferably with a tiny bit of water.) if you use a pipe, chances are it won't work very well at all.
2. smoke 1, or 2 bowls (3 at the most in one night). smoking copious amounts spread over the entire night won't increase your chances of having a trip. if anything, they will decrease them, and you will feel gross, or be unable to sleep well (like happened to you).
3. setting- very important! optimally, do it in a comfortable room, in a reclining chair, or on a bed. if you actually feel its effects, you almost certainly will want to lie down comfortably, in a quiet place. this isn't a party drug, and if you try it in a loud, busy place you won't see what it can do.
load a quarter gram of 10x extract into a glass bong (never a pipe). in order for saliva to take effect, it must stay in the lungs long enough to be absorbed fully.
(bearing in mind you've had a collapsed lung, i would wait until it is fully healed, or perhaps never bother smoking salivia at all.)
use a torch lighter preferably and light the bowl. fill the chamber with thick smoke and cover the top. take two deep breathes, fully inflating your lungs. breathe out completely, and breathe in a tiny bit of air before you pull on the bong.
fill your lungs well (lighting the bowl as you go if neccessary).
and now, the most important part....HOLD IT IN! as i said, it takes longer to absorb salivia than cannabis or other smokables. its not the quantity of salivia smoked over a prolonged time period that will get effects, but concentrated quality held in at one time.
hold it in as long as possible, and release. this should almost certainly work, in which case lie back, close your eyes (i usually use a dark room) and calmly allow it to work its magic.
if it almost works, repeat for one more bowl. (it helps to have someone you trust there to reload the bowl if neccessary, and take the hot bong when you are done with it. if not have a second bowl ready before you start smoking, in order to cut down on the time between hits).
use this method, and you are almost guaranteed to have one of the most intense trips of your life.
salvia isn't for everybody. if you try to abuse her, she will withhold her effects, or give you more than you bargained for. only try it ina good frame of mind, in a peaceful setting.
make sure you have healthy lungs first though :)
good luck.
