Users often make the claim that “sativas” produce a more “head-high” while “indicas” a more “body-high”, and that this could potentially be because of differences in THC content and CBD/THC ratio. However, there is no evidence to support the notion that CBD/THC ratios differ among the different types. Furthermore, nowadays there has been extensive crossbreeding which would make a further distinction between the types less meaningful.
