The four elements of addiction are: biological, psychological, social, and spiritual. On a biological level, addiction is characterized by changes in the brain's reward pathways that cause intense cravings for the substance or behavior. On a psychological level, addiction can be associated with underlying mental health issues or personality traits. Socially, addiction is often accompanied by negative consequences such as financial problems, relationship issues, and legal problems. Spiritually, addiction can lead to a sense of disconnection from the self, from others, and from a higher power.
