How should a human psych herself out?

Here is a web site where some people attempt to answer this question:

Many people use drugs as a substitute for changing relationships.  Self-medication with alcohol or
nicotine, or prescription anti-depressants and stimulants are easier than applying intelligence, focus
and analytical skills to complex relationship situations.  Drugs are also cheaper for patients (in the
short term) and more profitable for health professionals.

What do you think?
