Opinion
Lеandro Boyes appeals from his conviction of murder (Pen. Code, § 187), 1 attempted murder (§§ 664/187), and attempted rob *814 bery (§§ 664/211). The jury also found firearm use allegations to be true with respect to all three counts. The verdicts were returned on August 12, 1981.
On September 30, 1981, the trial court denied appellant’s motion for a new trial. It sentenced appellant to 17 years to life imprisonment for second degree murder as enhancеd by the firearm use finding. It imposed an additional consecutive term of three years representing one-third of the midterm for attempted murder as enhanced by the use allegation. Finally, it imposed a stayed sentence of eight months for attempted robbery.
Later, on October 20, 1981, the trial court vacated the sentence imposed on September 30. It ordered appеllant to serve the full midterm of 7 years for attempted murder consecutive to the 17-years-to-life sentence on the murder count with the use enhancement. It again stayed the attempted robbery sentence. The total sentence was thus 24 years to life, rather than 20 years to life as originally ordered.
On New Year’s Eve 1980, the decedent, Tony Zapeda, and Paul Perez went to thе St. Francis Hotel in San Francisco where they had several drinks. At 2 a.m., they drove to Cesar’s Palace on Mission Street; they parked up the street from the club. When they emerged from Caesar’s at about 4:30 a.m., they were unable to start the car. Zapeda removed his jumper cables from the car and opened the hood while Perez began walking back to Cesar’s to seek assistance from Zapeda’s cousin whom they had seen there. Before Perez reached the club, a black Lincoln drove by. Zapeda, standing in the street by his disabled car, said something like “All I need is a jump.” An occupant of the car shouted “Get out of the street, punk.” Perez heard three or four shots and saw Zapeda fall backwards. The Lincoln sped away.
Benny Andino, another patron of Cesar’s, observed the occupants of the Lincoln shortly before the shooting. Andino identified the driver of the vehicle as codefendant Eduardo Henriquez (who was acquitted on motion with respect to the murder and by the jury on the remaining charges) and the front seat passenger as appellant Leandro Boyes. After the Lincoln pulled away from the frоnt of Cesar’s, Andino saw it stop for a moment up the street. He heard three shots and saw the car “peel” away and turn right at the corner of Valencia and Mission.
Austin Fretty encountered the Lincoln and its occupants not long after the Zapeda shooting. At 5 a.m., Fretty was walking along Dolores Street on his way home from a New Year’s Eve party. At the corner of 20th and Dolores а man Fretty identified as appellant accosted him at gunpoint and *815 demanded money. Before Pretty could comply appellant fired, telling him “I’m going to kill you, punk.” Appellant fired another five rounds at Pretty, emptying the pistol. He walked away without picking up the money Pretty had thrown to the ground. Appellant walked to a large black car parked “catty corner” across the street. Pretty saw two other men and two women in the car. The victim was hospitalized and ultimately survived his wounds.
At 5:30 a.m., police officers investigating the Zapeda shooting saw the Lincoln parked at a Shell service station and detained its occupants. They were identified as Henriquez, the driver, Antoinette Imholz, the middle frontseat passenger, appellant Leandro Boyеs, the right frontseat passenger, and Ricky Rodriguez and Karen Denton, the backseat passengers.
A .38 caliber handgun was found in the waistband of Imholz’ pants. Police also found a box of .38 caliber ammunition on the floor of the car and two .38 caliber shell casings in appellant’s shirt pocket. Ballistics tests confirmed that the gun seized from Imholz had been used in the shootings of Zapeda аnd Pretty. Appellant told the police he could “barely remember” firing the gun. The officers stated that appellant appeared sober at the time of his arrest.
The two female passengers testified for the prosecution. Denton received immunity from prosecution while Imholz was permitted to plead guilty as an accessory to the charged crimes.
The womеn testified that they had been walking home from Cesar’s about 4:45 a.m. when Henriquez pulled up in the Lincoln and offered them a ride home. Imholz and Denton accepted. Henriquez, appellant and Rodriguez all had beers in their hands and appeared to have been drinking earlier in the evening. Appellant in particular was acting oddly. Imholz stated he seemed “really high” and was “just staring.” As they were driving away from Cesar’s, a man approached the car. Appellant shouted loudly at the man to get out of the street. Denton and Imholz then heard three shots fired from the front seat. They testified, however, that they did not actually see the gun in appellant’s hand. Similarly, Henriquez testifying in his own defense, claimed to have heard three “pops” from the front passenger seat but not to have seen appellant fire.
Henriquez drove the Lincoln away from the scene. Appellant sat impassively, displaying no emotion. Later, however, appellant suddenly became angry with Rodriguez for flirting with Denton and told him to “knock it off.”
As they were driving down Dolores Street, appellant suddenly told Henriquez to stop the car. Appellant said, “Wait a minute,” and ran aсross the *816 street. The other occupants of the car saw appellant speak to a man on the corner. They heard more “pops” and the man screamed, “No!” Appellant returned to the car and they departed. Again, he displayed no emotion.
Although the other occupants were only vaguely aware appellant had shot anybody on eithеr occasion, his behavior had by this time frightened them. Henriquez whispered to Imholz to hide the gun. She placed it under her sweater. Shortly later, police officers arrested the group at the Shell station.
A toxicologist testified for the defense that tests of blood and urine samples taken from defendant about 11 a.m. indicated that at 5 a.m. his blood alcohol level was apprоximately .15. The tests also revealed the presence of cocaine and PCP. His blood contained .03 micrograms per milliliter of PCP and his urine .07 micrograms per milliliter. The toxicologist testified that even a fairly low quantity of PCP can significantly alter behavior. Reactions to PCP vary among individuals. “Some just don’t do anything, just staring, and other people behave violently or other ones just don’t even hear anybody talking to them.”
Dr. David Smith, director of a drug abuse clinic, testified that the use of alcohol with PCP increases the probability of a violent reaction. On the basis of his interview with appellant in jail, Dr. Smith stated that appellant had a history of alcohol and PCP abuse, but had not used PCP for about four months prior to the New Year’s Eve incidents. Appellant told Smith that he had consumеd alcohol and cocaine that night and later smoked what he believed was simply a marijuana joint. The joint induced feelings of PCP intoxication, frightening appellant. Appellant told Smith he was only vaguely aware of what transpired during the rest of the night. “His sense became progressively more irritated and then after that has very vague and distorted recall of what transpired, had flashes of memory, distortions, disassociation, hearing a gun firing but not knowing what happened.”
On the basis of this interview and the results of the tests on appellant’s blood and urine, Smith concluded that appellant had been unable to harbor malice aforethought or the specific intent to rob or kill anyone at the time of the incidents. He admitted, however, that the levels of alcohol and PCP in appellant’s system would not inevitably prevent someone from harboring such intent.

B. Did the instruction on the rebuttable presumption of consciousness impermissibly lighten the prosecution’s burden of proof?
*817 The court defined unconsciousness and delivered the following instruction concerning its proof: “Evidence has been received which may tend to show that Defendant Boyes was unconscious at the time and place of the commission of the alleged offense for which he is here on trial. If after a consideration of all the evidence you have a reasonable doubt that the Defendant was conscious at the time the crime was committed he must be found not guilty.
“If the evidence establishes beyond a reasonable doubt that at the time оf the commission of the alleged offense the Defendant Boyes acted as if he was conscious, there is a rebuttable presumption that he was conscious, as to which rebuttable presumption the Defendant has the burden of raising a reasonable doubt.
“However, if, notwithstanding the Defendant’s appearance of consciousness, the evidence raises a reasonable doubt whether he was in fact conscious, you must find that he was then unconscious.”
Appellant contends the rebuttable presumption of consciousness contravenes

A comparison of federal decisions concerning various states’ presumptions and burdens of proof regarding self-defense illustrates the subtlety of the distinction between elements and affirmative defenses drawn in
Patterson
and
Engle.
A number of decisions hold that where a state characterizes a killing in self-defense as lawful and defines murder or manslaughter as an
*819
“unlawful” killing, absence of self-defense is actually an element of the crime as to which the burden of proof must remain with the prosecution.
(Tennon
v.
Ricketts
(5th Cir. 1981)
Section 26 includes unconsciousness among other conditions traditionally considered affirmative defenses, infancy, idiocy, ignorance or mistake of fact, accident and duress. At the time of appellant’s triаl, section 26 also included the defense of insanity. (See Stats. 1981, ch. 404, § 3, p. 1592; see current § 28, Stats. 1981, ch. 404, § 4, p. 1592.) Similarly, the case law on unconsciousness uniformly refers to it as a “defense.”
(People
v.
Ray
(1975)
Appellant concedes that the murder, robbery and attempt statutes do not expressly include consciousness as an element of the respective offenses. *820 (§§ 187, 188, 211, 663, 664.) Nonetheless, we recognize that consciousness is closely related to both the “actus reus” and “mens reа” components of each of the charged crimes since, as Sedeño indicates, it is pertinent both to the voluntariness of a defendant’s acts and to his capacity to understand and intend those acts and their consequences.
A close connection between a condition recognized as a defense and the elements of a crime does not compel the conclusion that absence of that condition is itself an element of the offense. Insanity, too, tends to undermine or negate voluntariness and capacity to harbor criminal intent.
(People
v.
Phillips
(1979)
Even more closely on point are recent federal decisions holding that a state may require a defendant to prove his intoxication at the time of an incident as an affirmative defense although the effect of that “defense” is to negate the intent element of the chаrged crime: “We agree . . . that it is not a denial of due process for the state to place on the defendant the burden of proof by a preponderance of the evidence of an affirmative defense which negates an element of the crime. [Citations.] Here, the state trial court carefully instructed the jury that the state had the burden of proving each еlement of the crime beyond a reasonable doubt. Although appellant had the burden of proving the affirmative defense by a preponderance of the evidence, such a requirement did not rely upon a presumption or improperly shift the burden of proof to the defendant in the way condemned by the Supreme Court in
Mullaney
v.
Wilbur, supra,
*821
As defined in the California statutes and case law and in the instructions delivered here, the elements of the respective crimes, including the required mental state, are conceptually distinct from the affirmative defense of unconsciousness despite the apparent “logical” overlap between these issues. The jury is first instructed that the prosecution must prove every element of crime including that of intent or spеcific intent beyond a reasonable doubt.
3
A subsequent instruction informs the jury that it must acquit the defendant if it finds he was unconscious at the time of his acts.
4
The prosecution bears the burden of proving beyond a reasonable doubt the appearance of consciousness, while the defendant’s only burden is to “raise a reasonable doubt” as to actual consciousness. As
Engle
indicаtes, this allocation of burdens does not mark consciousness as an element of the offense rather than an affirmative defense.
(Engle
v.
Isaac, supra,
Unconsciousness is logically inconsistent with the elements of the respective offenses. However, consciousness is not defined as an element. Accordingly, under
Patterson, Engle
and the decisions concerning insanity and intoxication, the very limited burden-shifting effected by the challenged instruction does not offend due process. Although a state may not “requir[e] a defendant to disprove what was in substance an element of the crime,” there is no constitutional bar to “requiring him to prove a defense . . . that may negative an element of the crime .... [Citations.]”
