Just received 100g 99.9% USP-grade anhydrous caffeine
this morning. Smokeable and sniffable, both with decent results, and I don't have to do any SWIMming because its caffeine!
Like Amadameus stated, caffine is actually quite palatable, at least compared to nearly every other flavored alkaloid
. Insufflated, the burn is mild (compared to, once again, nearly every other powdered, pure alkaloid) and the onset of buzz is worth it to me at least.
On a screen in a regular glass pipe, pulling moderately with light flame kisses nicely vaporizes the powder, and the resulting vapor is mild in flavor and harshness to the throat.
Insufflated, the only major drawback is the sneezes, which persisted after blowing my nose several times. The burning pain was quite mild, however. After I was dared to taste some crushed adderall
with my nose several years ago, I've been wary about putting alkaloid organic chemicals in there, but the sting of caffeine is minimal. A small amount of local anesthetic would cancel the burn altogether and leave only the sneezes.
Another common misconception: the freebase of an alkaloid is the only smokeable form. This is not the case, but it is usually preferred because the base is slightly more reactive than any salt, thereby coming on quicker (and in some cases metabolizing faster, too). It's a trivial difference if consuming in any way besides smoking, though, since the freebase of any alkaloid is reacted completely into the salt form once in the blood for a short number of minutes (pH buffers are good at that). If smoked, the freebase's increased reactivity brings the increased come-up speed and intensity which is what makes crack
so different from salt cocaine
. Smoked salts would have effects nearly indiscernible from insufflated salts. If the salt form of an alkaloid has different physical properties (higher boiling point, doesn't boil before it decomposes) it would be a poor choice to vaporize as an ingestion method, but if the freebase and salts have similar properties both could be smoked.
My 3 cents.
I'd like to add that insufflated/vaporized caffeine is the most profoundly effective laxative I've ever experienced.
