Coleman POT NOT A 'HARMLESS' SUBSTANCE Although marijuana has potential medical uses, its applications have been poorly investigated. As with any medicine there needs to be extensive testing and research before it is approved for use. Those of us who remember the tragedy of Thalidomide will appreciate this. Marijuana is not a harmless drug. It is profoundly mood altering and, as a result, some people develop problems from its use. Although there is ample evidence underscoring its hazards to various organ systems, as with any mood-altering drug marijuana's major effects are upon the central nervous system. Anything which so dramatically alters mood similarly impairs other aspects of brain function. To ignore these potential hazards when describing marijuana's effects is to ignore the most dangerous consequences of its use. Those with evolving drug misuse problems (particularly with prescription drugs) invariably tell their physicians that the only drug which relieves their symptoms is the one with euphoria-producing effects. Individuals with chronic pain and co-existing substance dependence disorders are difficult to treat. But time, care and patience often pays off and most are relieved of their symptoms without using mood-altering and addicting drugs. The rulings by various provincial court judges are not reflective of marijuana's true hazards. It is more reflective of good defence lawyer work. These decisions may have been different had those involved had access to more comprehensive and statistically relevant facts. There are many studies that clearly point out marijuana's hazards to various organ systems and its potential for addiction. Unless judges have access to these studies and the findings therein, however, they are liable to make decisions that are beneficial to neither those coming before them or to society. Finally, I would like to point out that those who most vigorously lobby for an expanded medical role for marijuana often do so in order to legitimize their own drug use. I would suggest that those most militantly supporting the Cannabis Compassion Club clearly have an agenda of their own. Douglas S.
