The AI-Powered Blood Alcohol Content (BAC) Calculator uses advanced artificial intelligence to provide a more personalized and accurate prediction of how alcohol affects each person. Considering weight, gender, age, amount of alcohol consumed and its content, the AI estimates BAC (blood alcohol content) and predicts how long it will take to become sober again. Important: the calculator is also aware of traffic laws and legal BAC limits in Brazil, helping users assess when they are at risk of exceeding permitted limits.

Why is Artificial Intelligence more accurate?

• Personalization: Traditional calculators use generic formulas. AI adjusts calculations according to each user's biological factors and habits.

• Learning from real data: AI learns from large databases, including real blood alcohol content (BAC) measurements, behavioral patterns, and physiological responses, becoming increasingly accurate.

• Considers complex variables: AI can include other factors such as food intake, drinking pace, physical activities, and even genetics (when available).

• Contextualized recommendations: AI doesn't just provide numbers – it guides you on when it's safe to drive, how long to wait, and what risks still exist, considering Brazilian legislation.

This tool is especially useful for making responsible decisions, such as knowing whether it's safe to drive or perform tasks that require full attention, reflecting Brazil's legal limits.

To accurately calculate the effects of alcohol on the body, the following important data must be provided:

1. Weight (kg): Body mass directly impacts alcohol absorption. The higher the weight, the slower the effect of alcohol on the body tends to be.
2. Gender: Men and women metabolize alcohol differently. Alcohol is processed more slowly in women's bodies due to the lower amount of enzymes responsible for breaking down alcohol.
3. Age: Age influences metabolism and how alcohol is processed. Over the years, this capacity tends to decrease, increasing the effects of alcohol. Older people may experience stronger or more prolonged effects compared to younger people, even with the same amount of alcohol.
4. Amount of alcohol consumed (ml): It is essential to provide the exact volume of the beverage consumed in milliliters.
5. Alcohol content (%): Represents the concentration of ethanol in the beverage, being an essential factor to determine the total amount of pure alcohol consumed.

6. Food intake (stomach content): The presence of food in the stomach strongly influences how the body absorbs alcohol.

   • Empty stomach – alcohol is rapidly absorbed into the bloodstream, quickly raising blood alcohol concentration (BAC).

   • Light meal – slightly reduces absorption rate, decreasing BAC by about 10%.

   • Full meal – considerably slows alcohol absorption. BAC can be up to 20–25% lower compared to consumption on an empty stomach.

   Including this factor makes the BAC calculation more accurate and contributes to more realistic estimates about the time needed to return to sobriety.

This information is essential to accurately calculate alcohol effects and assess the impact on each individual.

In Brazil, the Brazilian Traffic Code adopts zero tolerance for alcohol consumption while driving:

• Any blood alcohol concentration can be considered an offense, subject to fines and other penalties.

• Once the presence of alcohol or signs of intoxication is confirmed, the driver can be fined even without reaching a specific alcohol content limit.

• Fines
  Amount: R$ 2,934.70, which can double in case of recurrence within 12 months.

• License suspension
  The driver may have their license suspended for 12 months.

• Imprisonment
  In cases of traffic crime (accident with victims, refusal to test, evident intoxication): detention from 6 months to 3 years.

• Retraining course
  Mandatory to regain the right to drive after suspension.

• Vehicle and license seizure
  When caught in the act, the vehicle can be impounded and the license seized.

• Moderate your consumption – follow the "one drink per hour" rule.

• Eat before and during alcohol consumption to reduce alcohol absorption.

• Alternate with water – drink a glass of water between alcoholic drinks.

• Never drive after consuming alcohol, even in small amounts.
