Alcohol — What It Does to Your Body and Judgment

Alcohol-related accidents are a leading cause of death for people aged 15-24 worldwide. This isn't a scare tactic, it's a statistic. The reason is simple: alcohol is a drug that directly impairs the part of your brain responsible for good judgment. The most dangerous part? You are often the last person to realize how impaired you actually are.

Alcohol is a central nervous system depressant. That means it slows down your brain's processing speed, your reaction time, and your ability to make complex decisions. It works by boosting the brain's main 'off' switch (a neurotransmitter called GABA) and blocking the main 'on' switch (glutamate).Your level of impairment is measured by Blood Alcohol Concentration (BAC). While this varies by body weight and other factors, the effects are predictable:0.02-0.03%: Mild relaxation, lowered inhibitions. Your judgment is already slightly impaired.0.08%: Significant impairment of motor skills and judgment. This is the legal limit for driving for adults in many countries.0.15%+: Severe impairment. Blackouts (memory loss) become likely.0.30%+: Life-threatening. Risk of unconsciousness and death.Beca...

Diego, 17, was at a friend's house. He had two beers over a couple of hours and felt totally fine—just a little relaxed. When his friend needed a ride home, Diego volunteered, confident he was sober enough. On the way, he almost drove through a red light, slamming on the brakes at the last second. His friend was shaken. Diego was horrified. The next day, he used an online BAC estimator and realized he was likely very close to the legal limit for adults. He hadn't felt drunk, but his reaction time and judgment were clearly compromised. From that day on, he made a simple rule: if he drinks anything, he doesn't drive, period.
