A more thorough explanation:

An intoxicant is a substance, usually alcohol, that can make a person lose control of their senses or reasoning abilities.

Intoxication is a state of being where a person's mental and physical abilities are reduced due to the consumption of drugs or alcohol. For example, if someone drinks too much alcohol and becomes drunk, they are experiencing intoxication.

• Drinking too much alcohol and becoming drunk
• Taking drugs that impair your ability to think or move properly

These examples illustrate how an intoxicant can affect a person's ability to function normally and can lead to dangerous situations.

Involuntary intoxication occurs when a person is given drugs or alcohol without their knowledge or against their will. This can be a defense in criminal or negligence cases.

If someone puts a drug in your drink without your knowledge and you become intoxicated, this is an example of involuntary intoxication.

Voluntary intoxication is when a person willingly consumes drugs or alcohol to the point of impairment. This is not a defense for general-intent crimes, but may be used to refute a specific-intent crime.

If someone drinks alcohol before driving and causes an accident, they cannot use voluntary intoxication as a defense. However, if they are accused of a crime that requires a specific intent, such as premeditated murder, they may use voluntary intoxication to argue that they did not have the necessary intent to commit the crime.
