Overdose Warning Signs & Symptoms

Learn How to Notice the Overdose Warning Signs & Symptoms Before It’s Too Late

Every year, more and more people die from drug overdose. In just a decade, there was a 2-fold increase in the overdose numbers for the United States. In 2017, over 72,000 people fatally overdosed on prescription opioids and illicit drugs. Overdose warning signs are the last noticeable indication that a person is headed for a potentially fatal condition.

In this article, we will take a closer look at the addiction and overdose signs for several popular drugs, as well as how long it would take to break a physical dependence to each. If you notice the signs of overdose, then it’s important to seek immediate emergency care.


Heroin is in the opioid class of drugs. In the brain, the drug is broken back down into morphine, which then binds to opioid receptors, resulting in a lowered pain response and due to the dopamine increase, it also causes euphoria, especially when taken in higher amounts.

Heroin Withdrawal Timeline

The first phase of heroin withdrawal starts at day 1 and ends after about day 3, in which milder symptoms are experienced. Between day 3 and 5, symptoms begin to peak and then start to dissipate. The total time required to detox from heroin is roughly 5 to 7 days depending on each individual and the use of withdrawal medication.


Cocaine and crack cocaine are powerful stimulants that can be devastating when abused. But how much cocaine does it take to overdose? The amount that is it takes to overdose on cocaine can vary depending on what it was mixed with, how tolerant the person is to the drug, and other prior medical conditions. So, how much cocaine does it take to overdose on average? Generally speaking, the lowest amount that is considered fatal is 1.2 grams; however, since cocaine can affect people different, some may have an overdose on just 30 mg.

Since the body expels cocaine fairly quickly, the first symptoms are expected to show after around 2 to 3 hours. From day 1 to 7, the symptoms hit their peak including intense cravings that can lead to relapse. After roughly 10 days, most symptoms start to fade; however, cocaine is a drug that can cause post-acute withdrawal syndrome, which causes some psychological symptoms to persist for months, if untreated.


Even though alcohol is a legal drug, it is the most dangerous one there is. It is behind the deaths of around 6 people in the United States on a daily basis. The excessive use of alcohol not only causes an addiction and dependence, but it can lead to an overdose and death unless immediate care is found.

Alcohol Withdrawal Timeline

The first signs of withdrawal from alcohol start as early as 6 to 12 hours from caseation. From 12 to 48 hours, general symptoms are expected to appear and increase in severity. The most dangerous symptoms including delirium tremens appear after about 48 to 72 hours. If untreated, delirium tremens can cause death. After roughly 7 days of detox, a person is expected to feel much better as their symptoms fade.

Opioid-Based Prescription Pain Relievers

While these medications are the best at what they do – treating moderate to severe pain – they are also highly addictive, just like heroin is. Through an interaction with opioid receptors in the brain, opioid pain relievers block pain and flood the brain with feel-good chemicals such as dopamine. The result is a highly-addictive substance that can ultimately cause a fatal overdose.

The peak of the symptoms occurs at the 72 hour mark and the entire process is expected to be concluded after roughly 5 to 7 days.
