That happens a lot with store bought weed round here.
I think is is old remediated weed with no taste and smell then they add terps to it to make it more appealing.
Or it may be something added while the weed is growing like a sugar product or something to add flavor…not sure really but I have been asking what otheres thought about this sorta thing, but I have not gotten much feedback.
I refuse to smoke the shit myself, some folks think I am a weed snob, but I don’t know what I am smoking and I know my body does not like it at all.
I grow outdoors and indoors and I have never had that issue with what I grow.
