Dangerous Social Media Challenges

The influence of social media is broad, and its uses are more than just for entertainment. Pew Research Center (Pew) data shows that in 2021, 72% of all adult Americans used some form of social media. People sometimes participate in challenges and pranks that are trending on social media1. Some of the most popular include the ALS ice bucket challenge, Harlem Shake, and Planking.2,3,4 These trends and other trends range from harmless to downright dangerous. Some challenges have even caused death.5,6 Poison centers receive calls from people when these challenges go wrong. Below are some examples of challenges trending on social media and why they can be dangerous.

The Plan B Pregnancy Test Challenge

This challenge calls for breaking open a basic over-the-counter pregnancy test and swallowing the tablet inside the test believing that it is a Plan B® drug.7 The hope is that they purchased a combination product—both a test and an emergency contraceptive sold together.  One of the reasons a combination product is not sold is because it would not work. Plan B® needs to be taken soon after sex to prevent pregnancy, and a pregnancy test cannot detect a pregnancy until weeks later when it is too late to take Plan B®.  

The tablet found in a pregnancy test is put there to absorb moisture and keep the contents dry. These moisture-absorbing items come in a variety of sizes and forms such as tablets, packets, and canisters and are used in packaging of vitamins, medicine, electronics, shoes, and many other products. Silica gel is the most common chemical used for this purpose and in most cases is not harmful. However, if swallowed it can be a choking hazard.

The Nutmeg Challenge

This challenge is when a person swallows the spice nutmeg in an attempt to get high. Often it’s people who are incarcerated or young adults that use nutmeg when they can’t get other preferred drugs.8 Nutmeg, and a variety of other spices and herbs, contains a naturally occurring chemical called myristicin. When taken in larger amounts it can cause stomach pain, nausea, vomiting, blurred vision, fast heart rate, agitation, and hallucinations. Other severe effects such as seizures and death can occur. The amount of myristicin in nutmeg varies between products, making it is easy for a person to take too much. Some people have even been hospitalized from this trend.

The Salt Challenges

There are many social media challenges trending connected to salt. They include hiding a spoonful of salt in food to prank someone into eating it, swallowing salt before working out, or pouring large amounts of salt into their mouth as punishment after losing a bet.9

Table salt consists of two elements put together, sodium and chloride. Both of these are needed for the body to function properly, but too much can be dangerous. Swallowing large amounts of salt can quickly cause nausea, vomiting, and diarrhea. As salt is absorbed more fully in the body, sleepiness, brain swelling, and seizures can occur. Since we use salt in food every day, many people do not realize how dangerous it can be.  As little as a tablespoon in children and teens can be very harmful.

The Tide Pod Challenge

The Tide Pod challenge is when a person eats a laundry detergent packet as part of a dare.10 Laundry packets contain detergents and chemicals that are highly concentrated. This makes the detergent very irritating in small amounts. When eaten, they can cause nausea and vomiting. Also, when a packet “pops” in a person’s mouth, they can accidentally inhale some of the detergent into their lungs which can affect their ability to breathe normally. Eating laundry packets has caused hospitalizations and deaths.

The Benadryl Challenge

This challenge occurs when a person takes more than normal amounts of Benadryl (diphenhydramine) in order to hallucinate.11 Diphenhydramine helps with symptoms of allergies but if too much is taken, it has side effects such as hallucinations, high blood pressure, high body temperature, agitation, and seizures. Several teenagers have needed hospitalization, and at least one death has occurred from this challenge.

The Cinnamon Challenge

This challenge encourages people to eat a spoonful of ground cinnamon without drinking any water. This results in coughing, choking, and irritation of the mouth, nose, and throat. Some people find it entertaining to watch. However, serious effects can happen when a person coughs and chokes on the powdered cinnamon and then accidentally inhales it into their lungs.12 Cinnamon can irritate the lungs and even cause pneumonia. Some people engaging in this challenge have required hospitalization to help them breathe.
