I doubt it was Sativa that gives you the headache most likely the depo weed not all depos have great weed I would further this research go somewhere else another depo and try Sativa there…. Personally I’m a huge Sativa smoker India couch not for me during the day I need to be awake only at night also it would depend how you smoke it bong,bowl,jay all give different levels of the high anyway I would do more research my friend
