Anecdotally, such conditions have been common in strains that have high amounts of THC, and not much CBD. Haze was a big thing in the UK for a long while, as was Skunk. Both strains have high THC and little to-no CBD and these strains would cause me to flip badly. My friend who swears to never touch it again after he tried once and had bad-trip. When compared to other strains with more CBD, I would obtain more of the beneficial effects. And that it could also be linked to if the strain is Indica (in-da-couch) or Sativa with the same % of THC. Cannabis science an interesting field.
