A major obstacle in cannabis research has been the lack of a valid means of measuring the effectiveness of various treatments. (track and trend) Over the years, researchers have published hundreds of studies attempting to evaluate different benefits to medical usage of cannabis - marijuana. They have utilized biomedical, pharmaceutical, nuclear medicine, and psycho-educational interventions intended to benefit those with various diseases.

Much of this research has produced inconclusive or, worse, misconceptions, because there are no useful tests or scales designed to measure treatment effectiveness. Lacking such a scale, researchers have resorted to using scales such as the new Cannabis Treatment Rating Scale (CTRS) which were designed to diagnose - to tell whether or not a individual could be treated --and not to measure treatment effectiveness.

Two recent reviews have commented on the problem: "Often, investigators have to use diagnostic instruments to measure changes in response to treatment. . .this approach has not been very successful. . .because most diagnostic instruments. . .are not sufficiently sensitive to changes within an individual."1 " ...[M]easures of clinical improvement to validate treatment outcomes are even more seriously deficient."2

The Cannabis Treatment Evaluation Checklist (CTEC) was developed by Lynnice Wedewer Owner of the Cannabis Research Institute, to fill this need, which is especially urgent right now because of the new states approving medical cannabis and those still waiting for new cannabis reform.

The CTEC is a simple form designed to be completed by patients, parents, teachers, or caretakers.

Unlike most of the scales, it is not copyrighted and may be used free of charge by any researcher. Copies are available on request from the Cannabis Research Institute or at the CRI web site.

Users of the CTEC may have it scored free (4 subscores and a total score) by entering the responses via computer to the CTEC form on the website for immediate and free-of-cost scoring. CTEC forms are only accepted online.

We will ask you to fill out a few online forms to help us better track cannabis and its medical benefits through computer generated ratios. This will assist us with many aspects with a greater understanding of how cannabis helps each individual life and then track similarities.

A high-priority goal of the Cannabis Research Institute (CRI) is the development of improved methods of diagnosing individuals utilizing medical cannabis with severe behavior disorders, since most medical research and treatment is dependent upon accurate diagnostic methods.

CRI's Diagnostic Checklist, online Form, in which I developed. The Form checklist also asks patients to rate the effectiveness of cannabis and other various interventions utilized in their case, or loved ones they have tried on for instance their son/daughter. Information on the effectiveness of interventions is compiled on a regular basis and the resulting Patient Ratings of Cannabis ratings of Biomedical Interventions are shared with families and professionals throughout the world in a confidential way.

Our service to researchers depends in part on our having a comprehensive bank of up-to-date information about individuals utilizing medical cannabis and their outcomes. Your help in completing the online checklist and submitting them to CRI will be greatly appreciated.

The responses on the Cannabis Survey C1 Form are entered into a computer which calculates a diagnostic score. The score along with its interpretation is sent to the person or agency submitting the checklist. In addition, a file number is assigned to each individual for data recording and analysis, and to ensure confidentiality. There is no charge for this service.

Cannabis Medicinal Rating Form, a supplement to Form C-2, contains additional questions which are designed to explore a number of leads which have been uncovered in our search for the causes of specific diseases and how cannabis works from the patient and doctor perspectives to gain a complete story of the benefits of medicinal cannabis. This Form can be completed online or printed out and sent through the postal service. Upon completion of Form C-2. you will receive an email.

Note: there is no score derived from Form C-3; and therefore, there is no individualized report. An interesting and informative paper about autism is sent to the person or agency submitting a completed C-3 form as a token of our appreciation. Additionally, the information about your child will be kept permanently in our computer databank, so that it will be possible to contact you if future research produces relevant diagnostic or treatment implications.

If you are a medicinal cannabis user please do not forget to watch for the online forms to be available soon.

If you would like to complete the Diagnostic Checklist Form C-2, you can download and print the checklist (Adobe pdf file), and then mail it to the Cannabis Research Institute, 1906 K Street S.W., Cedar Rapids, IA, 52404.
