Seeing is believing, looks are deceiving: what does one see in images of drugs and drug use(rs)?

Images of drugs and drug use(rs) convey meaning, feelings, and beliefs, and what is being seen is often believed. Images can also deceive in content, meaning, and belief. Drug use(r) researchers, who use images as data, must be cautious in interpreting what is being conveyed and why. As technological advances continue to shape the creation, modification, storage, and analysis of images, researchers must be ever more vigilant about what they are seeing and believing.
