o Anxiety

o Agitation

o Paranoid thoughts

o Confusion and disorientation

o Intense feelings of alienation

o Depression

• Impaired memory

• “Flashbacks” similar to those experienced by chronic LSD users

• Persistent speech problems, such as stuttering, inability to articulate, or the inability to speak at all

• Chronic and severe anxiety and depression, possibly leading to suicide attempts
