Can I ask the effects of marijuana on blood pressure and blood thickness (in regards to plaquing, clot and thrombosis)... I asking about the actual plant and chemicals within...not anything about smoking(it or anything) or legality or psychological effects, religious effects, personal opinions.... I am an educated person but I struggling to find information that isn t either from anti drugs lobby, demands payment to private company, or keeps repeating the danger of smoking or mental health..even my cardiologist only knew the smoking aspect as it a illegal drug..he kept going on about how cocaine increases bp but wouldn t be drawn to any answer on cannabis(as in wouldn t even say it bad) except to say smoking bad Once again... Cannabis does it thicken blood and how does it affect blood pressure... ..NOT here for a drugs discussion just a simple question ...registered HCP answers appreciated
