Ok, im here again. Didnt went to another dimensions... yet.
From my yesterday's experiment:

I used a far greater amount of hash oil this time. Roughly 10x the amount i would smoke usually. This amount, if drank or eaten would get me reasonably high for a large amount of time.
Unfortunately, the weed i used for making this hash oil was not very good (some mids 9 months old ). I smoked it today, and the high was weaker than i would expect... so, probably it had a major influence in the results.

Anyway... this time i used (rougly) 0.15 cm3 of hash oil, 4 cm3 of alcohol and 1.5 cm3 of glicerin. Again, i did put the hash oil in the test tube, added the alcohol, shaked until dissolve all the hash oil, then added the glicerin, shaked until they mix, put the test tube in a can with boiling water and waited.
This time, not all the alcohol evaporated, even with almost 1 hour of heating. From the original 5.5 cm3 of the mixture, remained about 2.5 cm3, so, rougly 1 cm3 of alcohol didnt evaporated.

Also, this time the amount of the tar-like resin produced was far greater... of course, i used a far greater amount of hash oil, but also the quality of this hash oil was much worst, so probably it has more tars, useless resins, and so.
After cooled, the glicerin was murky green. I put it under the tongue for some 5 minutes and could clearly distinguish the taste of alcohol which had remained unevaporated.

After some 20 minutes, i started to feel the symptoms of a high coming... relaxation of the eyes, a slight heaviness of the members (as if i were doing things in somewhat slow motion) and so... Also, i felt slow-minded, and somewhat retarded...
The effects were increasing unsteadily, like waves... there was times i would feel i was high, then some minutes after i would feel very less high, then some minutes after i would feel very high again, and so...
I think i reached the peak after some 1.5-2 hours after the start. During the peak, i was almost as stoned as if i had smoked the hash oil.

So, i think it works. I used an amount that would make me high, and i went almost as high as i would expect from ingesting this amount.

There is some notes, though. This weed i used wasnt good indeed. I think it was too old. The effects i felt, putting under the tongue and smoking it were not much like the usual THC high, of the CBD stone. It were more like the CBN "messed" feeling, what makes sense, as the CBN is the product of the oxidation of the THC, what certainly happened cause the weed was very old.

Also, i think i used too much alcohol when dissolving the hash oil. I think if i had used less, probably there would not be any remaining alcohol in the tincture. Im not sure, but i think it may interfere in the absortion of the glicerin. Even if it does not, the taste of alcohol in the tincture is not good at all.

So, i think i can conclude this method actually works. Right now im isomerizing this "bad" hash oil i get, and if i get a decent high from it, i will try this tincture again.

If anyone were to try it, try to use the smallest possible amount of alcohol and glicerin, or, in other words, make the tincture as concentrated (strong) as possible. As stronger the tincture, smaller is the amount needed to put under the tongue, and faster the absortion. I think if you have too much tincture under your tongue (as i did), not all the tincture will be in direct contact with the "undertongue", and so not all the tincture will be absorved.

Tomorrow, the day after, or whenever i try to make the tincture with the isomerized hash oil im making, ill post again.

Meanwhile, if anyone try it, please post here the results. :thumbsup:
