Jessica Has a Drug Problem and Has Been Seeking Substance

Jessica has a drug problem and has been seeking substance abuse counselling. She has remained drug free for several months, but last week she ran into some friends with whom she used to frequently get high and she ended up using some drugs with them. Afterwards, she felt terrible about breaking her commitment to remain drug free and concluded that she must not have the self-discipline and willpower needed to quit. Within a week, she had fully resumed her harmful drug behaviour. This example best demonstrates the phenomenon called

A) the abstinence violation effect
B) the lapse justification effect
C) the multimodal effect
D) harm augmentation
