(2) The reason for the petitioner’s belief that because of such impairment the respondent has lost the power of self-control with respect to substance abuse; and either
(3)(a) The reason the petitioner believes that the respondent has inflicted or is likely to inflict physical harm on himself or herself or others unless admitted; or
(b) The reason the petitioner believes that the respondent’s refusal to voluntarily receive care is based on judgment so impaired by reason of substance abuse that the respondent is incapable of appreciating his or her need for care and of making a rational decision regarding that need for care.
