In addiction physiological dependence occurs when the body has to adjust to the substance by incorporating the substance into its normal functioning. This state creates the conditions of tolerance and withdrawal. Before moving forward to other chapters it will better to understand these two terms related to addiction:
Tolerance is the process by which the body adapts to the substance and requires increasingly larger amounts to achieve the original effects.
Withdrawal refers to physical and psychological symptoms experienced when reducing or discontinuing a substance that the body has become dependent on. Symptoms of withdrawal generally includes but are not limited to anxiety, irritability, intense cravings for the substances, nausea, hallucinations, headaches, cold, sweats, and tremors.
