Hallucinogens.
Hallucinogens are a diverse group of drugs that alter a person’s awareness of their surroundings as well as their own thoughts and feelings. They are commonly split into two categories: classic hallucinogens (such as LSD) and dissociative drugs (such as PCP). Both types of hallucinogens can cause hallucinations, or sensations and images that seem real though they are not. Additionally, dissociative drugs can cause users to feel out of control or disconnected from their body and environment.
I believe I learned this in my forensics class. The skeleton of an (older) female is usually determined by the pelvic region. The wide hips and cervix area. (As women grow their hips and cervix move outward in order to give birth and house a child) In adolescent skeletons the hips and cervix on the female haven’t moved outward yet. Therefore making both the male and female skeletons look almost identical in the region they most use to determine (the pelvic and hips) I hope that’s right and what you were lookin for!
