Opium addiction can have slightly different symptoms depending on the drug, the individual, and their frequency and volume of use. In most cases, users will show a range of physical, mental, and psychological symptoms relating to drug use, a changing pattern of behavior as their focus shifts to drug use rather than family, career, or study, and decreasing health as drug use takes its toll on the body.
A person with an opium addiction may doctor shop, where they visit multiple doctors or hold prescriptions from several doctors. They might purchase opiates outside of their prescription or even use prescription pills with other medication. They may hide pill usage. They may turn to using heroin or injecting opiates. And they might begin to change how they interact with others, such as by withdrawing, becoming more manipulative, asking for money, or otherwise changing personality.
