Addiction can look like intense craving and seeking out the use of a particular drug. Addiction has a lot to do with a lack of impulse control where a person with an addiction has the inability to resist the drugs their bodies crave. When you reject people who are addicted to drugs, they will start to become emotional and lose control, which can lead to negative results. Addictive behaviors can look like lying, stealing, manipulating, obsessing, and seeking addiction treatment. More characteristics of addiction can look like the inability to stop, denial, changes in appetite, and legal and financial problems.
