Thanks
@Vicki for that informative video.
In european medical market alcoholic tinctures are either made from fresh plants (mother tincture) or dried plants. No additives allowed. The final content of ethanol has to be in a certain range, depending on the plant and part of plant.
But it is a strongly regulated market.
I think it is important to state what kind of tincture people are using and what additives (terpenes, lecithin, sugars, etc.), if known or unknown.
Alcohol based tinctures are the way to go if you want sublingual uptake.
(Sativex is alcohol based IIRC and used as spray for sublingual uptake)
Glycerol based might
/should work too.
Fat based might give a little uptake sublingual, but the main uptake will happen in the guts.
Theoretically! I feel something pretty fast, too. What are your experiences?
Edit:
Italics
I am pretty sure THC-a does decarboxylate in alcohol or fat over time.
