Hi guys, a little update.
I've tried using glycerol. I've done 4 cold acetone washes of 2 minutes each, let it dry and then added glycerol, 2 ml. Don't know if salvinorin is completely soluble but it turn to a greenish color pretty fast and seemed like nothing was left in the cup.
I then took a syring and plugged the glycerol -BUT- maybe my methabolism is too fast, or something else, but the laxative effects of glycerol started to kick very strong after as little as 30 seconds, and I couldn't hold it. Fortunatly, knowing that this could happen, I tried it in the bathroom, so I just had to make one step to release everything.
I enjoyed the laxative effects of glycerol, less traumatic than a water enema and yet very effective in cleaning my intestine, but the experiment was a failure from the drug prospective.
I'll try other solvents and let you know.
Ah, thanks Vodsel for the link, I missed that topic, Very interesting indeed!
