Plant hormones would not be found in such high concentrations as THC. Plants produce a wide variety of compounds that have no direct role in growth and development. They are termed secondary products or secondary compounds. Examples include caffeine, nicotine, rubber and menthol. Their main functions appears to be in protecting the plant from herbivores and pathogens. THC's most likely function is thus to protect the plant from herbivores or pathogens.
