An overdose occurs when there are more drugs in the body than the body can handle. When an opioid overdose occurs, the brain gets overwhelmed with drugs and shuts down breathing. If breathing stops, the brain does not have access to oxygen, which will then cause the heart to stop within a short time. Generally, an overdose takes about 1 to 3 hours to occur after a drug is first used; therefore, just because nothing occured right away, don’t ignore the signs.
