THC and CBD change with technology all the time. It is hard to separate the two, but they have done a lot to progress with certain strains, like Stanley Brothers CW, CBG is a legal alternative that is less psychotropic. They are designed around hemp and high CBD, while getting the THC needed from Cross breeding with usually grafting in high THC to a hemp plant. There is also added infusion THC processes. Many ways to get there. We are hearing more about delta 8, but that is not a natural process and is still much controversy via the FDA and contamination even by quality brands and supposed 3rd party testing of removal of contamination is in question. Worst case is buying any products at your gas station or CBD store without doing your own lengthy research and discussing with your doctor.
