Use of the inhalant lança by Brazilian medical students.

In a recent epidemiological survey of more than 700 Brazilian medical students, we found new evidence on a previously reported pattern of the "lança perfume" inhalant drug use. With multiple logistic regression used to hold constant an array of suspected correlates, we found a moderately strong association between the use of marijuana and the use of lança (adjusted odds ratio, OR = 5.6; p < .01). We also found that lança is almost never used by students who have never consumed alcoholic beverages. This pattern of associations can be used to guide the planning of programs to reduce the occurrence of illicit use of pharmaceutical compounds by medical students in Brazil.
