Which statement best represents a valid criticism of the use of drugs to treat mental disorders

A)  Drugs are simply sedating patients rather than treating them, and drug treatments are very expensive. 
B)  Psychoactive drugs may produce superficial treatment but do not provide a cure, as evidenced by high relapse rates when the drug is discontinued. 
C)  Drugs appear to be effective only because they are prescribed to individuals who are likely to experience spontaneous remission. 
D)  Psychoactive drugs are all very addictive and there is a large withdrawal effect when the drugs are discontinued.

While psychoactive drugs can produce superficial treatment of mental disorders, they do not provide a cure, which is evidenced by the high relapse rates when the drug is discontinued. This is a valid criticism of drug treatment for mental disorders. None of the other answer choices accurately reflect valid criticisms of drug treatment for mental disorders. A is incorrect because some drugs may be expensive, but this is not a universal criticism of drug treatment for mental disorders. C is incorrect because while spontaneous remission can occur, clinical trials have shown that drugs are more effective than placebo in treating mental disorders. D is incorrect because not all psychoactive drugs are addictive and not all produce a large withdrawal effect when discontinued.
