Major assignments and expectations.

1. Read assigned material in the textbook and elsewhere, and use it to contribute to class discussions. Occasional, unannounced in-class or electronic writing assignments or quizzes will draw on your reading. You must read all of the assigned material, whether it is covered in class or not. Most readings will be useful in class discussion. As missed quizzes and other in-class assignments may not be replaced, perfect attendance is to your advantage. The course also has a home page, which may provide helpful information, including this syllabus. 10%

2. Three content examinations

Friday, May 14.............................15%

Friday, May 21.............................20%

Friday, May 28.............................25%

3. Paper or project (videotape, PowerPoint class presentation, Web site) on a topic approved by the instructor.

• Estimated paper length is 15pages, and electronic projects should demonstrate an equivalent amount of scholarship.
• Submit a proposal of one page in length by May 12, which explains your topic, tells why you want to do your paper on that topic, and lists the five best sources you have found so far.
• The final draft of the paper or project will be due May 26, and will be marked out of 15%. Correct English usage is expected.
• Use primary source material, including at least fifteen (15) journal articles. The journals may be either paper or electronic, but non-journal websites do not count toward the required 15 journal articles.
• In your paper or project, show a clear explanation of the topic, including relevant research and case reports.
• Suggested topics:
• Any drug or small family of drugs (eg. opiate antagonists), including history of its use and abuse, pharmacology, therapeutic potential, and current street status.
• Issues surrounding legalization of all drugs or any category of currently illicit compounds, such as marijuana.
• Targeted drug education methods.
• Treatment for addiction to a family of drugs, eg. heroin.
• Drug treatment of a particular mental disorder.
• Student electronic projects, both PowerPoints and websites, may give you some ideas.

4. Find and read current articles in newspapers, public affairs magazines, and popular magazines. These articles must deal with statistics about drug use, opinions or policy about drug use, development of new drugs, discovery of new uses for existing drugs, or discovery of side effects of drugs. A compendium of articles, many of which are relevant to this learning activity, is available from the National Clearinghouse for Alcohol and Drug Information. The compendium is updated daily.

a. Bring a synopsis of one articel to class for discussion each day.

b. Then, for each of the following due dates, choose one of the articles you have read, and do further scholarly research (books, journal articles, appropriate Web sites) to help you evaluate the article. Write a one-page critique of the claims made in the article, using your scholarly sources.

i. Due May 18

ii. Due May 25

(Total value: 10%)

5. Applied project. Take your pick of one of the following. If you prefer, suggest an alternative for my approval. Complete the project, write a one page report, and submit it by May 27, for 5% .

a. Visit a drug rehabilitation center.

b. Attend an open meeting of Alcoholics Anonymous, Al-Anon, Alateen, or a similar 12-Step group.

c. Take a free visit at a weight loss clinic.

d. Call a drug-information hotline (but not a crisis hotline, unless you are in a crisis). Inquire about two separate drugs of abuse.

e. Design and conduct an opinion poll, using a sample of at least 100 people who are over the age of 18. Report your results clearly.

f. Explore the training and credentialing requirements to become a drug abuse counselor in your home state.

• American Psychological Association

• The National Clearinghouse for Alcohol and Drug Information has a well-developed website, with survey results, a variety of drug education programs, and access to databases like Prevline, a searchable database of websites on drug topics.
• Food and Drug Administration

• National Institutes of Health

• National Institute of Alcohol Abuse and Alcoholism (NIAAA)
• National Institute of Drug Abuse (NIDA)

• Slang terms or street names for drugs can be identified via this dictionary.

• Read the 1997 speech by Gen. Barry R. McCaffrey, Director, Office of National Drug Control Policy.
• Then see how it played out in the 1998 National Drug Control Strategy.

• Several research reports and statistics on drug use are available on this site.
• Student Projects:
• Melissa Hobbs on methylphenidate/Ritalin treatment of AD/HD.
• Susan Ventresca on drug treatment of Bipolar Disorder. (Reference list)

• Substance Abuse and Mental Health Services Administration (SAMHSA)

• United States Information Agency (USIA) sometimes has relevant information, especially on internationals perspectives on drug use and trafficking.

• Web of Addictions: A commercial site which offers current drug information from an anti-drug abuse perspective.
