In British Columbia, the legal blood alcohol concentration (BAC) limit for fully licensed drivers is 0.08%. However, the question of how many drinks you can have before reaching this limit is more complicated than it might seem.
Several factors affect your BAC, including your body weight, metabolism, the type of alcohol you drink, and how much food you’ve consumed.
Factors That Affect Your BAC in British Columbia
On average, one standard drink — which is typically one beer, one shot of liquor, or one glass of wine — can raise your BAC by about 0.02%.
For an average person, consuming two to three drinks in a short period of time could put them close to or over the legal limit. However, for some individuals, even one or two drinks can push their BAC into the danger zone. This is because there are wide variations in the human population for weight.
The lighter you are the higher your BAC will be, and the heavier you are the lower it will be for the same amount of drinks. But body fat content also plays a role. As does gender. Women tend to have a 1.17% higher BAC compared to men based on consumption, but also tend to eliminate alcohol faster. In fact, some studies have shown that women tend to eliminate alcohol faster around their periods than when they are not menstruating.
Other factors that can affect your BAC is whether or not you have food in your stomach and the type of food. Healthy foods are less likely to slow absorption while fatty foods are more likely to do so. The rate of elimination of alcohol also has wide ranges within the population, often influenced by the degree of prior exposure to alcohol.
Why It’s Safer to Avoid Drinking If You Plan to Drive
The best advice is simple: if you plan on driving, it’s always safest to avoid consuming alcohol. There are many variables that make it difficult to determine exactly how much alcohol you can safely drink before driving. Factors such as your weight, gender, and the amount of food you’ve eaten can all play a significant role in how your body processes alcohol.
