Strains are hit and miss anyways, I mean unless you grow it yourself how can you know what strain your dealer got, half the time I feel like they just make the name up or use a popular high strength name to charge more
I have some Jack Herer wax that is 80% THC. I can smoke 3-4 huge hits with a lot of throat issues and an ok buzz. I have some Sour Diesel Mids that give me a more pleasant buzz. It is probably in the range of 14% THC. This proves that you need the whole plant to get your medicine if you are using for pain mgt. and is more of a realistic potency for good pot. IDK how they measure that in the 20 -30% levels unless it is from the tip of the best cola from a whole plant.
I used Zinc so much once that I could no longer taste anything at all for almost a month. Scared me a bit TBH.
