It sounds like you might be asking about misconceptions about blood alcohol concentration. For example, some young people might believe that if they have only had a little bit to drink, they are unimpaired. Others may think they can mask the effecfs of the alcohol.

Blood alcohol level is expressed as Gram Percent. That means grams per 100 grams of whole blood.  In most states the legal limit for blood alcohol in drivers is 0.08 Gm% (years ago it was higher, 0.10).  In many European countries the limit is far stricter, on the order of 0.06 Gm%.

A normal person will achieve a blood alcohol level of roughly 0.02 Gm% after one drink (1 shot of hard liquor, or 1 beer or glass of wine).

A chronic alcoholic who drinks daily will develop a tolerance to alcohol.  For a given blood level she may seem unaffected, whereas a naive drinker at the same level would appear to be grossly intoxicated.

A normal person with a healthy liver is able to metabolize (burn off) approximately 0.02 Gm% per hour.  A chronic alcoholic with cirrhosis of the liver may metabolize the alcohol much slower, and is in danger of intoxication after drinking an amount of alcohol that a healthy person could ordinarily handle.

I am not certain that I understand what you are asking but I will try to answer you. Blood Alcohol concentration (BAC) refers to the amount of alcohol in your bloodstream. The highe concentration of alcohol the more intoxicated the person is. However two similar people with the same BAC may be at different levels of intoxication depending upon several factors. These factores would include things such as increased toleration to alcohol, someone who is a regular drinker will be more likely to feel the effects than someone who rarely drinks.
