1. I think Martha is on methamphetamine. Long term effects of methamphetamine consist of anxiety, confusion, sleeping problems, and hallucinations. Short term effects are fast breathing, increased heart rates, increased blood pressure, and increased wakefulness. Martha had all of these symptoms with in the 48 hours she was in the observation room.
2. Methamphetamine increases the amount of the neurotransmitter dopamine in the brain. It is involved in body movement, motivation, pleasure, and reward. The drugs ability to release high levels of dopamine rapidly in areas of the brain produces the rush or euphoria that many people experience. Methamphetamine overstimulates the amygdala and compromises brain circuits needed to control impulse behaviors.
