Hi, pardon me, I must have read the study too quickly: in fact TINY amounts of CBD will convert to THC in your stomach, so I'm at least partly right.
Anyhoo...
I got the lab results back, my "mystery" cannabis is: 4% CBD, 3% THC, 1% CBDV and 0.5% THCV.
It seems the pollen from the THCV strain carried the "varin" gene into the pure CBD plant, and the hybrid grew out to the above.
So, I would say that hope is not lost. The only difference, is that I'm taking significant amounts of CBDV and THCV. Neither have been studied with regards to tinnitus, but I do find the "mystery", now no longer mystery, gives reason to move ahead. My friend who does the medical growing, under government permit, is able to procure CBD/CBDV seeds, and CBD/CBDV/THC/THCV seeds. This will take around 9 months to grow out to ripe dried flower, for further evaluation.
For the longest period (years) I keep saying to myself - why persist in this futile exercise that goes nowhere. Well, it did get somewhere, and now with the Health Canada HPLC lab values, it gives direction as where to go from here.
For example: The "Diet Durban" strain, which supposedly was on the website as 7% THC/ 7% THCV, on government analysis, was actually 13% THC and 0.5% THCV. But the "varin" gene was still there, and the pollen carried the gene onto a promising recipient. The seed vendor was contacted, and apparently there were some "problems" that have been "stabilized", meaning we can expect 7% THCV and 7% THC from the "stabilized" Diet Durban. So ok, some years have gone by with no "breakthrough", but what else is new, at least this is something, and apparently the original flowers from B1 B2 B3 were carefully searched by the grower, now encouraged by the results, and approx 12 more ripe seeds were discovered, that can be stored carefully and another round of 3 seeds can be germinated, with perhaps an even more promising hybrid, possibly one with even more CBDV. In any case, there does seem to be on the market now, seeds developed by horticultural researchers that have a stabilized high yield of CBDV, such as 6-8% CBD and 6-8% CBDV, in the same flower. So it is not necessary to grow out any more of the "found by chance" seeds, but buy commercially available ones. The seeds are around $15-25 US per seed, but the vendor states these are "photoperiod" which means that cuttings/clones can be prepared, as opposed to "autoflower" which only has one cycle, and cannot be "cloned" or propagated by cuttings.
Anyways, thanks to at least this slight advancement, I can say that my dependence on conventional pharmaceutical, which I already mentioned before, is drastically reduced, my memory seems to be working again, and I'm not all dragged out and hung over from pharmaceuticals.
So I would encourage if someone else is able to find/buy CBD/CBDV isolate/oil/tincture, and see "what happens" , I would be greatly interested, and I think we all here would be.
In the meantime my friend will be busy with a new batch of seeds, and see what she can do for us all here.
And just so not everyone think I'm out to lunch re CBD to THC, I was reading research, and the researchers came to that wrong conclusion. So I was going by older studies, shown more recently to be not valid.
As per:
In conclusion, both publications, that of Merrick et al. →
1 and Bonn-Miller et al., →
2 are unfortunately misleading in many aspects. Over 40 years of research on CBD does not suggest a conversion of CBD to delta9-THC and/or other cannabinoids
in vivo after oral administration. Such transformation occurs under artificial conditions, but is without any relevance for an oral therapy with CBD. Traces of delta9-THC in CBD
per se, although theoretically possible in less-purified CBD productions, are unlikely to be of concern as long as the intake does not exceed the LOAEL.
