According to everything I've read online tea does release it's caffiene more slowly. It's because another chemical called theobromine that's in tea that relaxes the body and slows caffiene's effect. Guarana's caffiene alkaloid is fat soluble (not water soluble) so it's absorbed much more slowly than water soluble versions. I don't think that theobromine would be a good idea to
vape due to it's very toxic nature (it's what kills dogs when they eat too much chocolate), and guarana's lipid version wouldn't vaporize right since it's oily.
Young padawan, you have much to learn. Step-by-step drug extraction walkthroughs are not adequate training. Read. Ask. Verify.
I shall break this down into sections which I feel warrant individual explanations.
First and foremost, caffeine is a chemical. It is the same chemical whether it is dissolved in coffee, sprinkled on a dead goat, or shoved into your rear end (yes it is used this way for medicinal purposes as part of an enema with multiple ingredients). Caffeine is at least partly soluble in everything from the polar solvents like alcohol and water, to the non polar (for the sake of this post we will associate non-polar with fatty and oil-dissolving) petroleum ether, acetone, benzene, etc. There is not an "oily version" and a "water-soluble" version, it is one chemical with the same properties wherever it goes. (quick side note, it IS possible to make caffeine salts but only when treated with high quantities of the acids and readily decompose into caffeine when exposed to air so it is unlikely that we will be dealing with these) Also note that many alkaloids can be present in salt forms (more water-soluble) and their respective base forms (often more lipid or "oily/fat-soluble") in natural sources (caffeine is not because it is a very weak base), so you were on the right track. However, (generally speaking) the base (or "oily") form almost always has a much lower boiling point (less attraction between the molecules than the salt forms, which are polar and attract eachother) so generally they would be more suitable for vaporizing/inhaling.
Second one is Theobromine. Yes, this is toxic to dogs in large doses, but it is not to humans in the amounts present in normal foods. Saying that it is of "highly toxic nature" is quite false. It is present in relatively large amounts in chocolate (ever hear of someone dying from chocolate poisoning?), and even dogs can eat reasonable amounts of chocolate with no ill-effects. In addition, roughly 10-20% (depending on your source) of the caffiene you consume is converted to theobromine by your body, so even if you take a pure caffeine pill you will have theobromine in your body. Plus it makes you feel good so if it is there who cares?
Back to caffeine, I believe the reason for your confusion on the "different types" is from anecdotal evidence on the stimulant effects of different caffeinated plant sources. Theobromine is actually known to synergize(sp?) with caffeine, boosting the stimulant effects. However, in teas there IS a chemical known as theanine
, which has a pseudo-tranquilizer effect, and is believed to be the reason for the lack of "jitters" from tea. However, the caffeine is still the same chemical and any difference in effect is due to the presence of other substances, not from a "different version" of the caffeine molecule. Thus, if properly isolated (100% caffeine, which is should be if you are attempting to vap it), the plant source is irrelevant.
Back to vapping caffeine, the boiling point of caffeine is actually slightly lower than that of PG (the main liquid component of most e-liquids), so vaporizing shouldn't be a problem, though whether one can vap enough to get any effects in a short period of time (caffeine has a much stronger stimulant effect when ingested in a short period of time as opposed to slowly absorbing over an extended period) is still a mystery. Also a warning to whomever attempts this: I found this on a MSDS for caffeine.
INHALATION:
CAFFEINE:
ACUTE EXPOSURE- May irritate the nose and throat and cause coughing and
chest discomfort. If sufficient quantities are absorbed, may cause
poisoning as detailed in acute ingestion. No deaths were reported in
rats exposed to 55 ppm for 4 hours.
CHRONIC EXPOSURE- If sufficient quantities are absorbed, may cause poisoning
as detailed in chronic ingestion.
Good luck, if anyone tries please post the results, would be much appreciated.
