We now know that biochemistry makes some people more vulnerable to alcoholism and drug use than others, so various proposed cures do not apply equally to everyone. Each person’s biochemistry reacts to alcohol differently, causing sleep, nausea, aggression, joy, relaxation, forgetfulness, sexiness, or tears. How their bodies metabolize alcohol allows some people to “hold their liquor” and therefore abuse alcohol, while others sweat and become red-faced after just a few sips, a response that may lead to abstinence. Alcoholism is inherited via psychological as well as biochemical tendencies. Some inherited personality traits (a quick temper, sensation seeking, high anxiety) encourage drinking and the use of drugs. Furthermore, some contexts, such as fraternity parties, make it hard to avoid alcohol; other contexts, such as a church social in a “dry” county, make it hard to find anything stronger than lemonade.
