Argument Linking Marijuana to Violence
/
A Wall Street Journal opinion is a good example of a persuasive argument for business communication students to analyze. The articles uses logical arguments, emotional appeal, and credibility; evidence is stronger for some points than for others.
The author provides research to support increased marijuana use in young people and to link marijuana use to mental illness and hospital visits. Is the evidence linking use to violence strong enough to convince students? The first study referenced studies of teenagers with mood disorders; the second is a meta-study that concludes, “cannabis use appears to be a contributing factor in the perpetration of violence.” Both are from credible sources and illustrate data analysis principles from Chapter 9 in the text.
I find the article title, “Cannabis and the Violent Crime Surge,” a misleading stretch. Coming just days after an elementary school school shooting—and when gun violence is a news mainstay—the WSJ implies a conclusion that I don’t see in the evidence. The author uses an example as evidence: the Uvalde, Texas, shooter apparently had a history of smoking marijuana. In addition, the argument is complicated by the claim that the shooter was NOT smoking at the time. Yet, he could have been experiencing detox, which may include anger and irritability. The author doesn’t include these points.
The author ends with, “Maybe it’s time that lawmakers and voters rethink their pot-legalization experiment before more young lives are damaged.” Do students agree?
