She has it in her head that because her life was hard, she deserves to have fun. I wrote her and let her know that I was concerned, and I wanted to help. She got very defensive, and said she only uses them recreationally. I don't know what to do. Dear Any Advice, It was good that you wrote, and that she got defensive.
Drug abuse can range from experimental or social use to dependency and addiction.
At this obvious addiction phase, her coworkers, supervisor, her child's daycare workers, fomerly unaware friends or relatives begin to take notice. Treatment is necessary for those who become chemically dependent and are unable to control their use. If your sister is at the social drug use phase, she may not need treatment. She might not progress beyond social use, and may decide to stop altogether when she finds the drugs are a drain financially and also have unpleasant side effects. Keep letting her know you are worried, so she is aware of your knowledge and concern.
