Acute effects

The acute effects of drugs, including drinking alcohol, are the immediate and short term effects.  Acute effects are those that people feel shortly after they ingest a drug and are under its influence (e.g., while they are intoxicated).

When a drug is ingested, the acute effects are felt quickly afterwards, but do not last the longest. Acute effects are usually the symptoms that users are seeking when using a drug, such as energy and euphoria from the use of methamphetamine.
