    There are a few purported high THC-V strains like Durban Poison, usually landrace African sativa ones. If you combust, you reach THC-V's boiling point of 428 degrees Fahrenheit. If you vape, you must vape to that temp to get that compound. But if you use Durban Poison for a tincture:

    1. Will the tincture (alcohol or glycerin) retain the THC-V via normal decarboxylation and extraction methods? Do people usually decarb or heat in any way to this high a temp? Is there any way short of that for THC-V to be in the final tincture?

    2. Why do typical analytical reports not report THC-V content?

    Don't be discouraged by the lack of replies. You have gone over my head, not that it means much.

    I am curious about what effects you are seeking in a sativa tincture as most are made from indicas for the sedative pain relief aspect.

    THC-V does start out on the plant as THC-VA, a carboxylic acid precursor to THC-V (see http://www.sciencedirect.com/science/article/pii/S0379073811001150).

    As such, yes, decarboxylation is required to achieve THC-V in your edible/tincture product. The difficulty here is that I have not yet found any article that outlines the decarboxylation temperature/time gradient of THC-VA into THC-V. THC-VA is not very well studied in the research literature and where mentioned in the articles I've found (like the link I shared above), is typically being considered as an analytical marker in drug testing used to differentiate between pharmaceutical formulations containing THC-V and use of botanical cannabis.

    Analytical reports may not report THC-V for a number of reasons. The most crucial reason is because THC-V is considered a rare, minor cannabinoid. It (well, its precursor THC-VA actually) is not commonly found in most of the varieties out there. As an aside, due to the above reasons, THC-VA is actually what you are more likely to find in botanical cannabis, not THC-V. This is similar to the fact that you're more likely to find much more THC-A than THC in botanical cannabis samples. The presence of THC-V or THC would indicate some form of thermal-oxidative decomposition of the sample.

    The reports may also not contain measures of THC-V in cases where labs only offer very limited testing (THC/CBD/CBN and that is all). A lot of testing results I've seen report very little of the information relevant to a cannabis user. THC-V/THC-VA are considered rare minor cannabinoids.

    I apologize that I could not help more, but unfortunately, this is not a question to which answers are easy to find :peace:

    The king of tincture makers (IMHO) is PsychadelicSam over at GrassCity.

    There is a stickie thread called Another Tincture thread try it you'll like it. Almost 800 pages, but you can ask and hopefully answer your question.
