Read the following article about whether recreational marijuana should be legalized and answer the questions.More than half of US adults, over 128 million people, have tried marijuana, despite it being an illegal drug under federal law. Nearly 600,000 Americans are arrested for marijuana possession annually--more than one person per minute. Public support for legalizing marijuana went from 12% in 1969 to 66% today. Starting with Colorado and Washington in 2012, recreational marijuana, also known as adult-use marijuana, has been legalized by ten states in the US. However, in spite of all these benefits that proponents have claimed, I still believe that the legalization of recreational marijuana will bring many problems.First of all, legalizing marijuana will do much harm to the teenagers. The percentage of 12- to 17-year-olds using marijuana is higher in every legal marijuana state than the national average. Compared to adults, teenagers are especially vulnerable to the side effects of marijuana because human brains are not fully developed until around age 25 (four years past the legal age in states that allow recreational marijuana). The American Academy of Pediatrics said that adverse effects of teen marijuana use include "impaired short-term memory and decreased concentration, attention span, and problem solving, which clearly interfere with learning. Alterations in motor control, coordination, judgment, reaction time, and tracking ability have also been documented; these may contribute to unintentional deaths and injuries."Secondly, marijuana use harms more than just the person using the drug. Societal costs of marijuana use include paying for increased emergency room visits, medical care, and addiction treatment for the uninsured; more victims of drugged driving accidents; increased crime; and a negative impact on health from secondhand smoke. As it was, legalized marijuana creates steep costs for society and taxpayers that far outweigh its tax revenues.(1) Which pattern of organization is adopted in this article?
