What are the two main types of dependence related to drug use?

The two main types of dependence related to drug use are physical and psychological dependence.

Physical dependence occurs when the body adapts to a drug, leading to tolerance and withdrawal symptoms if the drug is not taken. This means that the user's body becomes accustomed to the presence of the drug, and a physical need develops, creating a cycle where the individual must continue using the substance to avoid uncomfortable or painful withdrawal symptoms.

Psychological dependence, on the other hand, refers to the emotional and mental aspects of addiction. It involves a perceived need or craving for the drug to cope with stress, anxiety, or other emotional issues. Individuals may feel that they cannot function properly without the drug, which reinforces their behavioral patterns related to drug use.

Together, these two types of dependence provide a comprehensive understanding of how drug use can affect individuals on both a physiological and emotional level, highlighting the complex nature of addiction. The other options, while related to the broader conversation about drug use and health, do not categorize dependence in the same way that physical and psychological do.
