WHICH METHOD IS BEST?
There are pros and cons to each method. Some people report that the quid method produces a deeper, more visionary experience than smoking. Others report that chewing doesn't work for them at all, but smoking does. For those who get little effect from either method, the two methods can be combined. First chew a quid, and then, after spitting it out, light up. If you already smoke tobacco or Cannabis you will probably be comfortable with smoking Salvia. If you are a non-smoker you will probably prefer the quid method. Bear in mind that smoking anything, even Salvia, can't be good for your lungs. Unlike smoke, orally consumed Salvia does not irritate your lungs.
It requires quite a bit more dried leaf when taking the leaves as a quid than when smoking. Smoking is the most economical way to use the leaves.
The quid method produces effects that come on more gradually and last longer. They are better for exploring Salvia's world. They are better for deep meditation.
Salvia tincture (e.g. "Sage Goddess Emerald Essence®") has the same effects as a quid method, however the dosage can be adjusted more precisely, the effects come on somewhat faster, and holding the not-unpleasant tasting tincture in one's mouth is much nicer than holding chewed up leaves in your mouth. The only side-effects reported that are unique to the tincture have been "burning" of the lining of one's mouth. This occurs if the alcohol in the tincture has not been sufficiently diluted. It may leave one's mouth mildly sore the next day, in much the way that it would be if you drank soup that was scalding hot. This problem can be prevented by diluting the tincture with enough water.
Generally speaking, it is best to avoid overly-concentrated extracts, vaporizers, and pure salvinorin A. Chewing quid, using tincture, smoking leaves, or smoking mild to medium-strength extracts will produce sufficiently strong effects for most people. There is no need to experiment with stronger and more dangerous ways of taking Salvia.
There are some people--albeit a minority--who, even after many experiments, find they remain "Salvia-hardheads." They never experience more than a slight Salvia effect from smoking, or from a quid. Some of these hardheads will get satisfactory results if they chew a quid, and then immediately smoke after spitting out the quid. Others will find even this ineffective. For them, extract-enhanced leaves are necessary to produce effects. See how sensitive you are before experimenting with stronger forms of Salvia. With a little practice, quid chewing, or smoking, or combining the two ("boosting"), works quite well for most people. Many people find it takes several meetings with Salvia before a "breakthrough" experience occurs. So don't label yourself a "Salvia-hardhead" too soon.
