Higher doses of this drug can cause a person to experience erratic behaviors, including violence, anxiety, panic, and paranoia. The chemical compositions of the hallucinogens are similar to the neurotransmitters serotonin and epinephrine, and they act primarily by mimicking them. Combining drugs is dangerous because their combined effects on the CNS can increase dramatically and can lead to accidental or even deliberate overdoses.
