At least one teenager has died who used powdered pure caffeine obtained in bulk over the internet. These products are 100% caffeine, and a single teaspoon is equivalent to about 25 cups of coffee. Overdoses can cause rapid or dangerously erratic heartbeats, seizures, and death. The U.S. Food and Drug Administration advises all to avoid these products.
PositiveTip: Parents must communicate the potential dangers of these products with their teenagers and young adults.
