smoking salvia Divinorum from a pipe.

[yamman13]

the other day swim bought two grams of salvia 10x, and went to a quiet park with two friends to light up. When swim inhaled, he found it too be extremely harsh, and couldn't properly hold it in because he felt like he was about to throw up.
So, swim smoked about half a gram in total, in several small hits, but he didn't properly hold it in for long enough. As a result of this, swim got the giggles for ten minutes, and found it highly enjoyable, but was a bit disappointed that he didn't get any more hallucinogenic affects.
Swim has two questions. The first one is; is it normal just to get the giggles after 0.5 grams of salvia 10x? swim was expecting a bit more, although he realizes its probably because he didn't hold it in properly.
The second question is, is there anyway to make smoking it less harsh? perhaps a salvia joint, but swim isn't sure if this would work properly.
