What are some connections between World State and our society that uses medication that is socially acceptable to promote social stability?

Soma, as used in Brave New World, and the large amount of antidepressants prescribed today have a similar effect. In our modern age, antidepressants are seen as a cure-all.... if they make you feel better.... you are better. Rather than treat the problem, a bandaid covers the wound that will never heal because the problem isn't addressed. Living in a haze is better than living in reality, and when the population lives in a haze.... they can be convinced about just about everything. Just don't take the happy pills away, most people will do anything to keep them. Whether or not this is a viable way to promote social stability is for you to answer.

Note, there are a number of people who use antidepressants in conjunction with proper therapy.
