The use of cannabis as a mood stabilizer in bipolar disorder: anecdotal evidence and the need for clinical research.

The authors present case histories indicating that a number of patients find cannabis (marihuana) useful in the treatment of their bipolar disorder. Some used it to treat mania, depression, or both. They stated that it was more effective than conventional drugs, or helped relieve the side effects of those drugs. One woman found that cannabis curbed her manic rages; she and her husband have worked to make it legally available as a medicine. Others described the use of cannabis as a supplement to lithium (allowing reduced consumption) or for relief of lithium's side effects. Another case illustrates the fact that medical cannabis users are in danger of arrest, especially when children are encouraged to inform on parents by some drug prevention programs. An analogy is drawn between the status of cannabis today and that of lithium in the early 1950s, when its effect on mania had been discovered but there were no controlled studies. In the case of cannabis, the law has made such studies almost impossible, and the only available evidence is anecdotal. The potential for cannabis as a treatment for bipolar disorder unfortunately can not be fully explored in the present social circumstances.

Improvement in the quality of gynaecological smears using a cytobrush.

For accurate cervical cytology an adequate sample of cells must be obtained from the squamocolumnar junction. In 100 patients conventional smears were compared with smears and membrane filter preparations made using a cytobrush. A satisfactory cell smear was obtained in 39% of patients using the conventional method and in 97% the cytobrush. When membrane filter preparations were used in conjunction with cytobrush smears, adequate cytological samples were obtained from all patients.

Can drugs be used to enhance the psychotherapeutic process?

Many preindustrial cultures traditionally use certain psychedelic plants to enhance a procedure that resembles psychotherapy--an idea that was also tested in Western psychiatry in the 1950s and 1960s. LSD and related drugs were used to facilitate the production of memories, fantasies and insights and to enhance the therapeutic alliance. The results were inconclusive, and research was largely abandoned after the drugs became difficult to obtain. It may now be possible to revive this research, using new drugs that do not have some of the disadvantages of the old ones. The drug now of most interest is MDMA (3,4-methylenedioxymethamphetamine) a relatively mild and short-acting substance that is said to give a heightened capacity for introspection and intimacy without the perceptual changes, emotional unpredictability, and occasional adverse reactions associated with LSD. Therapists who have used the drug claim that it can enhance the therapeutic alliance by inviting self-disclosure and promoting trust. Whether MDMA fulfills this promise or not, other drugs may eventually prove useful in psychotherapy. Research on their potential should not be curtailed because of fear that they will be subject to illicit abuse.

Coca and cocaine as medicines: an historical review.

Coca has been used in folk medicine in South America for thousands of years both as a general stimulant and for more specific medical purposes. It remains one of the most commonly used medicines in some areas of Bolivia and Peru. The medical use of coca and cocaine in the industrial world has a more dramatic and varied history. Coca extract and cocaine were introduced as pancreas for a wide variety of complaints in the late 19th century. Cocaine was the first effective local anesthetic; prescription drugs, patent medicine, and soda drinks containing it were also popular. When its dangers became apparent and substitutes became available, its medical use went into decline, especially when, in the 1930s, amphetamine began to replace it for some purposes. Today its only generally accepted medical use is as a topical anesthetic in certain kinds of minor surgery and other clinical procedures. There are, however, some recent and so far uncertain signs of reviving interest in cocaine and even coca itself for other medical purposes, in research as well as in diagnosis and treatment.
