a relatively new term in the cannabis world, used to categorise the different cannabis strains/variants according to their chemical components. The term originated when researchers began to identify the genetic markers that distinguished THC-rich cannabis strains from CBD-rich cannabis strains. Here they talk about 3 main chemotypes: THC chemotype, CBD chemotype and a mixed THC/CBD chemotype (e.g. varieties with THC/CBD content in the ratio 1:1, 2:1 etc.).
