Consumption, possession and production of a drug may be prohibited, legalized or decriminalized. In all regimes illicit production of a drug may take place and drug-related crime occurs. We show that illicit drug...

The majority of natural history studies of human immunodeficiency virus (HIV) infection have immune and viral parameters in men. Data demonstrating that women have lower HIV-1 RNA levels than men at the same CD4 cell counts have raised the question of immunologic differences in HIV-seropositive women. This study describes levels and changes in phenotypic markers of immune maturity, function, an...
