Answer:
The correct answer is letter "A": "I am never going to use crack again".
Step-by-step explanation:
People who abused drugs or alcohol and who went into a detoxification program are released only when specialists consider there are good possibilities that person will not fall under the same vice again. Otherwise, the patient will need a longer admission time until that person is aware of the consequences that might bring the continued abuse of drugs.
In that case, the best remark of an ex crack addict upon release from a detoxification program is "I am never going to use crack again".
