Al Capone-type traffickers who are role-models for the young". The lack of government regulation and control over the lucrative illegal drug market has created a large population of unregulated drug dealers who lure many children into the illegal drug trade. The U.S. government's most recent 2009 National Survey on Drug Use and Health (NSDUH) reported that nationwide over 800,000 adolescents ages 12–17 sold illegal drugs during the previous 12 months preceding the survey. The 2005 Youth Risk Behavior Survey by the U.S. Centers for Disease Control and Prevention (CDC) reported that nationwide 25.4% of students had been offered, sold, or given an illegal drug by someone on school property. The prevalence of having been offered, sold, or given an illegal drug on school property ranged from 15.5% to 38.7% across state CDC surveys (median: 26.1%) and from 20.3% to 40.0% across local surveys (median: 29.4%). Despite more than $7 billion spent annually towards arresting and prosecuting nearly 800,000 people across the country for marijuana offenses in 2005, the federally funded Monitoring the Future Survey reports about 85% of high school seniors find marijuana "easy to obtain." That figure has remained virtually unchanged since 1975, never dropping below 82.7% in three decades of national surveys. Environmental With respect to drug crop cultivation, eradication efforts in line with prohibitionist drug policies ultimately force coca, poppy, and marijuana growers into more remote, ecologically sensitive areas. These crops, which are generally grown away from urban centers and state presence, tend to deplete forestland and expand the agricultural frontier. Out of fear of eradication, cultivators are incentivized to accelerate production cycles in order to obtain the highest yield in the shortest period of time; the pace and methods used by growers neglect measures to promote sustainability, exacerbating the environmental impact. Drug cultivators typically opt to produce in areas with ecosystems with abundant plant biomass to better conceal their operations. Ultimately, this practice leads to increased deforestation which contributes to a greater influx of greenhouse gases into the atmosphere. Moreover, the aerial spraying of herbicides such as glyphosate used in eradication and control efforts have been shown to have negative effects on environmental and human health. The "balloon effect" also operates further up the drug commodity chain in countries where drugs are trafficked rather than cultivated. Like eradication programs, interdiction pushes traffickers into remote areas where they exacerbate preexisting pressures on forestland. Traffickers use slash and
