Good questions PsyDuckmonkey. I wrote something similar earlier in this thread. And thanks THanoC for your reply.

I cant get pure ethanol, only 96%. And it seems like a hassle to use 100%. Perhaps you could dry it as with acetone but I hope to find other ways. So using 96% ethanol it will have 4% water that will turn into vapor inside the sealed jar. perhaps a small amount of water is 'better' than oxygen. I don't know. But it kept me from trying. That and that I cant find a good air tight jar that don't have plastic in the lid. As I wrote consumer jars have metals lids with a plastic lining that is now safe for higher temperatures (over 100c). Probably there are other jars that are better but I cant find them.

So. I did the folding foil version. As I wrote when trying out a small bit (0,5ml) I found it containing less THC then expected. But yesterday I did a bit deeper dive and took 1ml with would be around 62ml THC if it had been a 50% conversion. mixed the alcohol (96%) it with a bit of hemp oil and held it sublingual fro some minutes then swallowing. Not much happened for over 2,5h... then something. Really really slowly I wound notice that I was getting stoned. And when I went to bed, about 3h after intake I was indeed high. Not as if I would have taken 62mg of THC (I think) but definitely effected  In a nice clean/clear way. I went to sleep, waking up a few times during the night with a really nice body feeling, and mind. Good times in all.

I have not taken THC mixed with CBD orally before so I don't have prior experiences to compare it to. But I liked it. Will try out more, but not to much to soon. Don't want to get into daily cannabis usage as before.
