I want to do my annotated bibliography on drugs and the mental and physical effects (both positive and negative) it has on the human body but it is such a broad topic and i've found that narrowing it down is quite a challenge. I've been doing research to try and narrow my search to only a couple drugs or chemicals and their effects but even that has turned out to be a challenge. I've decided to spend one more day researching the topic and if i cant narrow my research down to one question then i might just have to find another topic to research.
