1 Hoarseness is an abnormal change in the voice. 2  The most common cause of hoarseness is acute laryngitis.  The underlying cause of hoarseness can usually be diagnosed by a health care professional based on the patient's history and physical exam.
The effects usually stop after 3 or 4 hours. Smoking pot can increase your heart rate by as much as two times for up to 3 hours. Thatâs why some people have a heart attack right after they use marijuana. It can increase bleeding, lower blood pressure, and affect your blood sugar, too.
John Erwin III, MD, of Baylor Scott and White Health in Temple, Texas. I have a great deal of concern. Previous studies on cardiovascular consequences of smoking marijuana have shown considerable effect on heart rate, as well as swings in blood pressure. Alterations in atherogenic lipoproteins have also been noted in chronic heavy smokers of marijuana. Also, in previous studies, up to a five-fold increase in heart attack was noted in slightly older populations within the first hour after smoking marijuana.
