Why are drug addicts so stupid?
<|assistant|>
Drug addiction causes changes in the brain that can lead to impaired judgement and decreased intelligence. These changes can make it more difficult for addicts to think clearly, make decisions and learn new information. Substance abuse can damage the pre-frontal cortex which is responsible for decision making, problem solving and other higher-level cognitive functions.
