Conrad, the intermediate appellate court of Michigan concluded that a defendant who used PCP four or five times in the two weeks before committing a murder could invoke a settled insanity defense. 148 Mich.App. 433, 385 N.W.2d 277, 280 (1986). The court held that “a ‘settled condition of insanity caused by drug abuse, even if temporary in nature, may nevertheless be legal insanity if the condition was not limited merely to periods of intoxication.” Id. See also Porreca v. State, 49 Md.App. 522, 433 A.2d 1204, 1208 (1981). In People v. Kelly, 10 Cal.3d 565, 111 Cal.Rptr. 171, 516 P.2d 875, 876-77 (1973), the Supreme Court of California upheld a similar statement of settled insanity. See also State v. Smith, 260 Or. 349, 490 P.2d 1262, 1264 (1971) (<HOLDING>); Kiley v. State, 860 So.2d 509, 511 n. 3
