"Roughly speaking, this hypothesis asks whether drug use causes some of the diseases officially associated with AIDS, such as immunodeficiency and Kaposi's sarcoma"

This quote by Serge Lang is referring to the hypothesis that drug use might be a contributing aspect to the advancement of illness associated with AIDS. Particularly, the hypothesis suggests that drug use might be a cause of immunodeficiency and Kaposi's sarcoma, 2 of the most typical illness connected with AIDS. This hypothesis is necessary because it could help to describe why some people are more likely to establish these diseases than others. If substance abuse is found to be a contributing factor, then it might cause much better avoidance and treatment techniques for those at threat. Furthermore, it could assist to lower the preconception related to AIDS, as it would recommend that substance abuse is not the only cause of the illness. Eventually, this hypothesis might provide important insight into the causes of AIDS and assist to improve the lives of those impacted by it.
