some facts that are wrong hear
ak-47 is called ak-47 because it "packs a hit" this is what the creator, serious seeds said.
it is not generally 22 percent thc, more around 18 as labs tested
hash is much more than 22, can be from 55 to 80 APROXIMATELY
There are several strains with more thc content. the highest known now is G-13, which measured 28 percent thc.
thc is measured in a lab. it is the thc content in the female bud. Don't ask me how they do it, but that is the measuring standard. trichomes will have the same amount of thc as hash.
