There have been no documented cases of death from LSD overdose. (There was one reported, but it was later found to NOT be LSD that caused her death). However, overlarge quantities of LSD can cause severe hallucinations, panic attacks, and suicidal feelings.
An overdose of LSD substantial enough to cause life-threatening physical symptoms is thousands of times the recreational dose, and therefore is not typically a risk to the average user. However, LSD may certainly cause frightening psychological effects and a risk for dangerous behavior when ingested in excess.
An overdose of both substances is possible. While a PCP overdose could certainly prove fatal, an overdose of LSD is very rarely fatal and would likely cause only an extremely unpleasant and overwhelming altered state with anxiety and panic.
