## Core Concept
Tactile hallucinations are a type of sensory hallucination where an individual feels sensations on their skin that are not based on any real stimulus. This phenomenon is often associated with neurological or psychiatric conditions.

## Why the Correct Answer is Right
The correct answer, **Cocaine Bugs or more formally, formication**, is a well-documented condition related to cocaine use. Cocaine affects the brain's dopamine and serotonin systems, and its chronic use can lead to a condition known as cocaine-induced paranoia or cocaine psychosis, where users experience tactile hallucinations, commonly feeling like bugs are crawling under their skin (formication). This condition is directly linked to the pharmacological effects of cocaine.

## Why Each Wrong Option is Incorrect
- **Option A:** While alcohol withdrawal can cause a range of symptoms including tremors, seizures, and delirium tremens, it is less commonly associated with pure tactile hallucinations compared to the specific sensation of formication seen with cocaine use.
- **Option B:** Schizophrenia is a psychiatric disorder characterized by a range of hallucinations and delusions. While tactile hallucinations can occur in schizophrenia, they are not as uniquely characteristic or specifically associated with this condition as formication is with cocaine use.
- **Option D:** Amphetamines can cause a variety of psychological effects, including hallucinations. However, the specific and classic association of tactile hallucinations (like formication) is more strongly and uniquely linked to cocaine use.

## Clinical Pearl / High-Yield Fact
A key point to remember is that formication or the sensation of bugs crawling under the skin is a classic symptom of cocaine-induced psychosis. This is a high-yield fact for exams because it's a specific and somewhat unique association that can help differentiate between causes of hallucinations.

## Correct Answer: C. Cocaine Bugs/Formication
