Love Just Kana!
I have only had a few instances where I needed customer support and the company did their job and fixed the issues. I also have confidence in the product I’m purchasing.
Best tasting and best quality
I found this particular strain (in regular cannabis flower form) possesses the terpenes that work well for my uses. I simply wanted an accurate representation of the same symbiotic relationship MINUS the experience of the pyshocactive components. Bingo! Ordering again now! Thanks for taking this seriously. The entire industry appears to have used medically-related issues to open up the industry, then abandoned us for those interested in (essentially) recreational use. You all have gone over and beyond to protect no only the integrity of the science and the process(es), but have also taken care regarding the very ingredients—literally, from the ground up! Well done!
I am a pot heavy smoker since using it for years, and then using it heavily through Breast Cancer 4 years ago. Although it is legal and readily available where I live, I noticed I was starting to have some cognitive decline (67) and heavy munchies (bad for an emotional eater.)
So I decided to try no THC. I have enjoyed my new Vape. I miss being high sometimes but much more clearheaded. The bad news is I think this strain still gave me nighttime munchies.
