Differences Between Sexes
There exists a higher rate of relapse, shorter periods of abstinence, and higher responsiveness to drug-related cues in women as compared to men. One study suggests that the ovarian hormones, estradiol and progesterone, that exist in females at fluctuating levels throughout the menstrual cycle (or estrous cycle in rodents), play a significant role in drug-primed relapse. There is a marked increase in progesterone levels and a decrease in estradiol levels during the luteal phase. Anxiety, irritability, and depression, three symptoms of both withdrawal and the human menstrual cycle, are most severe in the luteal phase. Symptoms of withdrawal not associated with the cycle, such as hunger, are also enhanced during the luteal phase, which suggests the role of estradiol and progesterone in enhancing symptoms above the naturally occurring level of the menstrual cycle. The symptoms of craving also increase during the luteal phase in humans (it is important to note that the opposite result occurs in female subjects with cocaine addiction suggesting that cyclic changes may be specific for different drugs of abuse). Further, the drug-primed response is reduced during the luteal phase suggesting a time in the cycle during which the urge to continue use may be reduced. These findings implicate a cyclic, hormone-based timing for quitting a drug of abuse and preparing for magnified symptoms of withdrawal or susceptibility to relapse.

Famous quotes containing the words differences between and/or differences:
“The extent to which a parent is able to see a child’s world through that child’s eyes depends very much on the parent’s ability to appreciate the differences between herself and her child and to respect those differences. Your own children need you to accept them for who they are, not who you would like them to be.”
—Lawrence Balter (20th century)
“The country is fed up with children and their problems. For the first time in history, the differences in outlook between people raising children and those who are not are beginning to assume some political significance. This difference is already a part of the conflicts in local school politics. It may spread to other levels of government. Society has less time for the concerns of those who raise the young or try to teach them.”
—Joseph Featherstone (20th century)
