>>21323248i say that where there is physical dimorphism in the plants that allow us to differentiate between sativa and indica, there is no perfect pattern of effects to match their shape.
much of the physiological effects are the result of the always dynamic combination of genetics, in both the plant (the additional variable is terpenes) and the user.
when it comes to my decades of exp, ive seen that you need to pick a reliable source for a certain strain, and try it to see how it makes you feel.
i can account for more than a dozen random strains that break the mind race/couch lock dichotomy.
