Which statement accurately describes the effect of intoxication on criminal liability?

• A. Intoxication is always a complete defense.
• B. Intoxication shall not be a defense to a criminal charge, but may change the required mental state.
• C. It cannot affect the mental state.
• D. It requires that the intoxication be voluntary for it to affect the case.

Answer: (B)

Understanding mens rea is key here: a crime is not just about what you did, but what you intended or knew when you did it. Intoxication isn’t usually a blanket excuse that wipes out liability. Instead, it can affect the mental state required for the offense.

That’s why the best statement is that intoxication is not a complete defense to a criminal charge, but it can change the required mental state. If a crime requires a specific intent or purpose, intoxication might prevent you from forming that intent, potentially leading to a lesser offense or no conviction for the specific crime. If the crime only requires general intent, intoxication often won’t absolve liability. Involuntary intoxication can sometimes be a defense because it may prevent forming the required mental state at all.

So the idea is: intoxication can alter the mental state necessary for liability, but it doesn’t automatically remove liability in every case.
