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.
Marijuana does do damage to your lungs, puts a strain on your cardiovascular system, and impairs certain functions of the brain, but alcohol does all this and a HELL of a lot more. Also, the withdrawal of alcohol alone can do more damage to your heart than smoking marijuana. With that being said, Marijuana IS a drug (well THC is actually lol), and it is addictive IF you use it multiple times a day for a month or more.
