To accurately calculate the effects of alcohol on the body, the following important data is required:

1. Weight (kg): Body mass has a direct impact on alcohol absorption. Higher weight determines a slower effect of alcohol on the body.
2. Sex: Women's and men's bodies process alcohol differently. Alcohol is metabolized more slowly in women's bodies due to lower amounts of enzymes responsible for breaking it down.
3. Amount of alcohol consumed (ml): The exact volume of alcoholic beverage consumed in milliliters must be indicated.
4. Alcohol content (%): This indicator shows the concentration of ethanol in the beverage. It is an important factor in determining the total amount of pure alcohol consumed.
5. Time of first drink (optional): If you enter the time of your first drink (clock time), the calculations are anchored to the time of day and show how sobriety varies throughout the day — this allows you to see your estimated sobriety for the current moment. If you do not enter the time of first drink, the calculation is presented in relation to elapsed time (hours passed) since consumption began, comparing levels by hours instead of linking them to specific times of day.

This data is essential to accurately calculate the effects of alcohol on the body and assess its impact on different individuals.

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.
