Physical addiction/dependency to drugs means that the body has become accustomed to the presence of the drug and requires it to function normally. Physical dependency can manifest as physical withdrawal symptoms when the drug is not present. Psychological addiction/dependency to drugs means that the person has a strong emotional attachment to the drug and relies on it to cope with stress or other emotions. Stimulants such as caffeine or cocaine can cause increased alertness, energy, and euphoria, as well as increased heart rate, blood pressure, and respiration. Long-term use can lead to insomnia, anxiety, and addiction.
