Consuming alcohol before or during shooting increases the risk of incidents because it impairs coordination, hearing, vision, communication, and judgment.
Drugs can have a similar effect. If you have to take prescription medicine, check with your physician to see if it's safe to take while shooting a handgun.
Because you can drink faster than your system can burn the alcohol off, there is an increasing level of alcohol in your blood. This level is referred to as Blood Alcohol Concentration (BAC).
The best thing you can do for your safety and the safety of others is simple…Don't drink and shoot!
