I have used commercial tinctures, but making the tincture yourself will yield about the same results, at a far lower price. There is a bit of time and effort involved though. The tincture experience is much milder than smoking, but lasts longer. I prefer to chew extract enhanced leaf myself when taking Salvia sublingually, as tincture can burn quite a bit. For example, if you chew 1 gram of 20X, that would be equivelent to chewing 20 grams of raw leaf, which would be equivelent to several dropperfulls worth of tincture (although the alcohol base does help with absorbtion). This is really only cost effective if you are making your own extract enhanced leaf though, otherwise it can be kind of expensive.
