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 usually has a sedating effect on most users, making it much less likely to cause violence in users than other substances such as alcohol and stimulants (e.g., amphetamines and cocaine). However, sometimes when marijuana is used it can cause fear, anxiety, panic or paranoia, which can result in an aggressive outburst. For most people, once the effects of the drug wear off, their behavior gradually improves.
