Answer

### Step-by-Step Solution for the Causes of Tobacco Addiction

1. **Understanding Tobacco Addiction**: Tobacco addiction primarily stems from the psychoactive effects of nicotine, which is the main addictive substance found in tobacco products.

2. **Physical Health Issues**: One of the significant health issues caused by tobacco addiction is the development of gastric and abdominal ulcers. The chemicals in tobacco can irritate the stomach lining, leading to ulcers.

3. **Mechanism of Ulcer Formation**: When tobacco is consumed, it enters the digestive system and can cause inflammation. This inflammation can disrupt the protective lining of the stomach, resulting in ulcers.

4. **Misconceptions**: It is important to clarify that not all diseases are caused by tobacco addiction. For instance, anthrax is an infectious disease caused by bacteria and is not related to tobacco use.

5. **Conclusion**: Therefore, the primary cause of tobacco addiction is the presence of nicotine, which leads to various health complications, including gastric and abdominal ulcers.
