I've always found strains with Columbian, panamanian, share similar qualities to haze smoke.
Obviously the smell is a big one, but if you've smoked these kind of strains the smoke itself is so light, it seems to drift on and fill a room with the lightest, best incensey/spicy weed smoke.
Vs a heavy stinky strain like of kush etc which has a heavy, oily, stinky smoke that sticks to everything.
I have not been able to try pure Thai so I can't comment on that but I definitely see the possibility of a central American/Columbian connection to haze.
i have an heirloon acapulco line that very much reminds me of haze to the point it makes me think its an ingrediant
