Yep it's all marketing mumbo jumbo for sure. People say terpenes cause different effects and the reality is that w don't know if these effects are do to some psychoactive interaction or it's essentially aroma therapy. "This weed smells like lemons, I like lemons, therefore this weed brings me an extra level of enjoyment". Terpenes exist in many botanicals, it's not like you get a different high from gin vs tequila because of the different terpene content. Even if there are repeatable effects from different strains we have not at all supported it with scientific based evidence
