[National study of drug habits in Uruguay].

The results of a prevalence study of alcohol abuse and drugs use in the general population of the República Oriental del Uruguay are showed here. A national household sample was drawn from the most important urban areas and 2500 persons, aged between 15 and 65 years, were selected and interviewed. Illicit substances use (include use of any of the following: marihuana, cocaine, inhalants, hallucinogens) reached 4.5% for the lifetime prevalence period, 1.1% in the last twelve months and 0.7% for the last thirty day. Twenty percent of the sample classified for tobacco dependence, and alcohol abuse, in the last 30 days, was 19.5%. Significant associations, by sex and age, were found.

[Patterns of drug abuse among youngsters of upper social class].

Street drug use, and alcohol abuse among young adults from a high social class range were studied in the posh seaside resort of Punta del Este (Uruguay) during the (austral) summer vacation (February 1993). In this connection, an anthropological methodology was applied: Four young people were trained in systematic record and observation technics abilities. Results suggest two clearly defined social-cultural patterns with regard to both cannabis, and cocaine use. Both patterns take place within a social environment agreeable to drug use as well as strongly connected with social interaction ways peculiar to high-class youth.

Characterization of bioacceptable carbon materials.

Bioacceptable carbon films deposited with a new low temperature technique have been investigated using Raman and X-ray photoelectron spectroscopy. Our results reveal a substantial similarity between the low temperature deposited film and the well-known bioacceptable low temperature isotropic (LTI) pyrocarbon. The Raman spectra, as well as the larger density and oxygen content in the bulk, lead to the speculation of the presence of the common tetrahedral bonds in these materials.
