A Therapist States, "I Seldom Use Drugs When I Treat

A therapist states, "I seldom use drugs when I treat clients with borderline personality disorder." The therapist MOST likely says this because:

A) the risk of suicide increases because using drugs may lead to overdose.
B) in most cases, drugs seem to make aggressiveness even worse.
C) in most cases, drugs seem to make emotional outbursts even more extreme.
D) the therapist is unaware that drugs are always used in combination with dialectical behavior therapy, the most effective therapy for those with borderline personality disorder.
