Pubdate: [Sat, 01 Mar 1997] Source: Chicago Sun-Times (IL) Author: Arthur R. Sobey Regarding the column (Feb. 16) by Mary Mitchell, "Advising kids to say 'No' when you said 'Yes,' " The maxim "truth is the first casualty of war" is particularly true in the war on drugs. A prohibition, accompanied by harsh sanctions, is a sure stifler of truth. Mitchell spoke from her heart in her courageous column. While I applaud her, I don't condemn those who are silenced by fear of imprisonment, job loss and public ostracism. Predictably, the imprisonment of taxpaying pot smokers and the destruction of their families has failed to show any success in halting the flow of drugs to schoolchildren. Zero-tolerance "reefer madness" propaganda also has failed. When intelligent teens, like Mitchell's son, seek out authority figures for guidance on marijuana, they are entitled to the same truths they are taught in math or English. Arthur R.
