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 can also cause more health problems if you have a condition like liver disease, low blood pressure, or diabetes. If youâre a man, heavy use could lower your testosterone levels, and your sperm count and quality. That, in turn, can zap your libido and fertility.
