Family members might fight a lot because of the problems the drug use is causing. The person who is using drugs might do and say things that upset neighbors and friends and make the family ashamed.
Some people who are addicted don't believe that they are sick and out of control, so they don't look for treatment. They don't see the problems they're causing. Other people who are addicted are aware of the problem but may be so upset and confused that they don't know how to ask for or get help, or they're afraid to stop using drugs.
