Paranoia cd come from a lot of things. Imo the biggest reasons are the social stigma surrounding cannabis. And the fact that its illegal means that we only get to see a perversion of cannabis. Too high in THC and too low in CBD. Unnaturally grown with tap water, chemical fetilizers and pesticides. Who knows what else is laced in street dealt cannabis when you dont know who grows it or how its grownn also growing in water gives the high an ungrounding effect.

Lack of omega 3s might also be another. Also yes I vouch for raw cannabis concumption over smoked or heat processed atleadt in the long term.
