The prevalence and correlates of single cigarette selling among urban disadvantaged drug users in Baltimore, Maryland

BackgroundSelling of single cigarettes, also known as loosies, is a public health concern. Loosies allow for those with fewer resources to buy cigarettes without having to purchase a pack. Selling of loosies may cue smoking behaviors. In the US, socioeconomically disadvantaged populations have high rates of smoking and illicit drug use and the selling of loosies appears to be linked to the urban informal economy. We examined the proportion and frequency of cigarette selling and roles in the informal economy associated with selling loosies among a sample of urban drug users. MethodsThere were 801 participants, recruited by community outreach, assessed at baseline, who were enrolled in an HIV prevention intervention for drug users. ResultsMost (89%) smoked cigarettes in the prior 30 days, of whom 92% smoked daily. Self-reported selling of cigarettes was common with 58% reporting that they had sold cigarettes within the last six months; 20.4% reported selling cigarettes a few times a week and 7.4% reported daily selling of cigarettes. In a stepwise regression model, four sources of income were associated with frequent cigarette selling: providing street security (OR=2.214, 95% CI 1.177–4.164), selling food stamps (OR=1.461, 95% CI 1.003–2.126), pawning items (OR=2.15, 95% CI 1.475–3.135), and selling drugs (OR=1.634, 95% CI 1.008–2.648). ConclusionThere is a high rate of selling loosies among urban substance users. The wide availability of loosies may promote smoking. Smoking cessation programs with drug treatment and economic development programs may help to reduce economic pressures to sell loosies.

Wall Street Looks at Uranium

CRANIUM is a very great subject, one of the greatest the world has known. No one. writer can tell all about it, even in a very good book, and a number of fine books have already been written. I will tell you my personal experiences with it, because, as a Wall Street security analyst working for a large financial house, they are probably different from those you have read about before. Two great men in nuclear energy were my basic teachers. One was John Menke, president of Nuclear Development Corp. of America, and the other Dennis Viles, vice president in charge of uranium for the Vanadium Corp. Both are personalities. John is still young. An intent Wall Street over-the-counter trader before 1939, he left the brokerage business and studied nuclear physics at Columbia. One of his teachers was the famous John Dunning who started the gaseous diffusion process. John was able to make me realize ...
