cannabis lowers blood pressure ... it dilates the blood vessels, allowing more flow, thus, lower pressure ... I have gone from 4 BP drugs per day, to 2, just from smoking a bit of pot at night ... and, the regulated pressure lasts throughout the next day ... this, after taking 4-7 BP pills per day, for over ten years, with no improvement whatsoever ... my cardiologist is fuming, he's losing all his drug-company bonuses for pushing their friggin' pills ... :smokin:
