Drug abusers of LSD or psychedelics will possess glassy eyes and a blank look. They will sometimes appear like daydreamers and ignore things, which are said to them. Barbiturate abusers like Valium and other depressants look lazy and sleepy. They fall asleep in remote places and also have falling, slurred speech, droopy eyelids and a general drunken appearance. Drug abusers of opiates like heroin and morphine have pinpoint pupils. An opiate drug abuser has itchy skin and he frequently scratches.  Often, individuals who have a problem with drug addiction will not admit that they have a problem.
