There are six stages for short-term consequences of alcohol misuse.


For most people, the first effect of drinking alcohol is a feeling of euphoria and confidence. Drinking less than half a glass of alcohol in an hour is enough to affect your inhibitions, self-control, will power, judgment and concentration.


When a person’s blood alcohol level is between 0.09 and 0.25%, they become excited and lose balance more easily. Reaction speeds will be affected.


With a blood alcohol level of 0.18 to 0.30%, a person may stagger around and could feel confused and emotional. Motor skills become impaired.


When a person’s blood alcohol level reaches 0.25 to 0.4%, they’re likely to be jittery and nauseous. Reflexes are severely impaired. They may fall in and out of consciousness.


When a person’s blood alcohol level reaches 0.35 to 0.5%, they could pass out. At this stage, they may end up in hospital.

Serious Consequences

A person that has consumed enough alcohol to take their blood concentration to 0.5% or over, could face breathing complications or even death.
