There is no doubt that active cannabinoids in cannabis have medicinal possibilities but what i’m saying is by definition cannabis is a drug much like sugar. You may find changing strain might help with the paranoia, stay away from sativa if this is causing you issues.
Who knows , but i have smoked it a few times ! and because i had been in trouble with the law a lot in my past , when i smoke it , i get into very deep thinking and then the paranoid thoughts come ! so i could say it might help on the medical side of it , but its fucked for the brain thinking pattern !
