The Writer Responds The responses focus on denying the dangers of marijuana use (that it is addictive and causes car crashes), personal anecdotes about marijuana as "medicine," and justifications for bypassing the approval process of the Food and Drug Administration. I point Mr. Anton to the 2010 National Survey on Drug Use and Health showing that marijuana users have the highest rate of dependence of all those classified with illicit drug dependence. Higher potency marijuana is a major factor in the increasing number of Americans being treated for dependence. Common sense and studies confirm that marijuana-related driving problems include decreased handling performance, slower reaction times and lack of motor coordination. Studies in recent years have linked marijuana to many health problems, including birth defects, respiratory system damage, cancer, brain damage, strokes, immune system damage, mental illness, violence and infertility. Although many people like Mr. Sikov report that marijuana benefited them, anecdotal reports are not reliable scientific evidence and can be influenced by the emotional expectations of the person, the sedative-hallucinogenic effect of marijuana, and politics. Public health must be protected based on unbiased science and objective clinical testing. The F.D.A. did a comprehensive study and found that "no sound scientific studies supported medical use of marijuana." Its sophisticated drug approval process is our best defense against marketing unsafe and ineffective drugs. That is true compassion for the ill.
