explain why it is difficult for a person to stop the drug or alcohol use and addiction

In society, many people link abusing drugs or alcohol to an individual’s lack of personal responsibility or morality. Prior to American model Anna Nicole Smith’s death, which was from an apparently accidental overdose of several prescription medications, her son, Daniel, had died just months before from an apparent drug overdose. This incident poses the question of whether the son inherited a vulnerability to addiction from his mother or was the habit picked up from living with her over the years. Post should be at least 400–450 words in length.
