¶1The appellant, Earl Thompson, was indicted by the Thomas County Grand Jury for a violation of OCGA § 16-13-30.1
¶21. The appellant contends OCGA § 16-13-30.1 (Ga. Laws 1982, p. 2370) is unconstitutional in that it violates his right of due process as guaranteed by the state and federal constitutions. Specifically, appellant argues the statute violates due process because it subjects him to a greater penalty for the sale of a non-controlled substance than for the sale of some controlled substances. All violations of this statute subject the violator to a penalty of one (1) to ten (10) years imprisonment or a fine not to exceed $25,000, or both. There are no distinctions in penalties made for the type of non-controlled substance sold, or the type of controlled substance it is represented to be. The penalty for the sale of Schedule III, IV and V controlled substances and marijuana is one (1) to ten (10) years imprisonment with no fine. OCGA § 16-13-30 (h) (j) (2).
¶3In support of his contention that the disparity in penalties under the two statutes violates due process, appellant relies upon People v. Wagner, 89 Ill.2d 308 (433 NE2d 267) (1982), where a similar statute was held unconstitutional. Appellant urges this court to adopt the rationale applied in that case and hold our statute unconstitutional. In Wagner, supra, the majority opinion of the Illinois Supreme Court held that it was obvious, even without an express legislative finding, that delivery of a controlled substance is a greater threat to the public than delivery of a non-controlled substance. Therefore, to impose a more severe penalty for the latter offense than the former could not reasonably be designed to remedy the evil. The majority relied on the former opinion in People v. Bradley, 79 Ill.2d 410 (403 NE2d 1029) (1980). But, as the dissenters pointed out, in Bradley, supra, there was an express legislative determination that delivery of a controlled substance was a more serious offense than possession of that substance, hence the latter could not reasonably be punished more severely than the former.
¶4*395Our Controlled Substances Act contains no express legislative intent that a person who sells a non-controlled substance represented to be a controlled substance has not committed a more serious offense or should not be punished more severely than one who sells certain controlled substances. The fact that the legislature recognized the differences between the harm associated with various types of controlled substances by providing different penalties for the various types does not govern the statute under consideration in this case. When the legislature enacted OCGA § 16-13-30.1 it was dealing with an entirely different problem from that associated with the sale of controlled substances. We do not know the magnitude of the problem or evil associated with the sale of a substance represented to be a controlled substance and we cannot hope to be as adequately informed as to the nature and extent of the problem as the legislature was. The legislature could have found that the sale of non-controlled substances represented to be controlled substances is a serious health hazard to those who use the substance or that a substantial breach of the peace brought about by the violence emanating from this species of fraud is a greater threat to the public. We are simply not in position to say whether the evil sought to be remedied by OCGA § 16-13-30.1 is not as great a threat to the public health, safety and welfare as is the delivery of certain controlled substances. This is a matter to be determined by the General Assembly. This court will not substitute its judgment for that of the General Assembly in regard to the penalty to be imposed for violations of the statute. Hodges v. Community Loan &c. Corp., 234 Ga. 427, 431 (216 SE2d 274) (1975). The General Assembly has the means of informing itself, and it has seen fit to make this classification, which we do not find irrational. Therefore, the trial court properly denied appellant’s motion to dismiss the indictment.
¶52. On November 26, 1984 the trial judge entered an order in which he found the defendant indigent and appointed Harry Jay Altman II to serve as his attorney. On February 5, 1985, after undertaking representation of the defendant but before trial, Altman filed a motion to withdraw as counsel in which he pointed out that an associate attorney in his law firm had become the Solicitor of the State Court of Thomas County, a part-time position paid by Thomas County. Altman relied on an informal opinion of the Office of General Counsel for the State Bar of Georgia dated December 11,1984,
¶6There are competing interests of significant proportions at work in this issue. The State Bar has filed an amicus curiae brief urging a per se rule of disqualification from the practice of criminal law in this state of all attorneys in a law firm, one member of which is a part-time solicitor of a state court. The State Bar is quite properly anxious to assure that all lawyers exercise their professional judgment solely for the benefit of their clients.
¶7Until local and state governments devise means to avoid the necessity of part-time solicitors, we decline to impose a per se rule of disqualification. Instead, we hold that an actual conflict of interest must be shown in order that a partner or associate of a part-time *397solicitor of a state court be disqualified from representation of a defendant in a criminal case before a superior court. This must be done on an ad hoc basis. Hudson v. State, 250 Ga. 479 (1) (299 SE2d 531) (1983); State ex rel. Starnes v. Erickson, _ S. D. _ (186 NW2d 502) (1971).
¶8In rendering its opinion of disqualification the State Bar relied on a substantial number of ethics opinions from other jurisdictions which tend to support the opinion.
¶9Judgment affirmed.
¶10 OCGÁ § 16-13-30.1 provides in relevant part, “(a) (1) It is unlawful for any person knowingly to manufacture, deliver, distribute, dispense, possess with the intent to distribute, or sell a noncontrolled substance upon either:
¶11(A) The express or implied representation that the substance is a narcotic or nonnarcotic controlled substance;
¶12(B) The express or implied representation that the substance is of such nature or appearance that the recipient of said delivery will be able to distribute said substance as a-controlled substance; or
¶13(C) The express or implied representation that the substance has essentially the same *394pharmacological action or effect as a controlled substance.”
¶14 The substance of the informal opinion is now embodied in Formal Advisory Opinion No. 44.
¶15 “A lawyer shall decline proffered employment if the exercise of his independent profes*396sional judgment in behalf of a client will be or is likely to be adversely affected by his representation of another client, except to the extent permitted under Standard 37. A violation of this standard may be punished by disbarment.” Standard 35, 241 Ga. 736 (1978).
¶16 “Maintaining the independence of professional judgment required of a lawyer precludes his acceptance or continuance of employment that will adversely affect his judgment on behalf of or dilute his loyalty to a client. This problem arises whenever a lawyer is asked to represent two or more clients who may have differing interests, whether such interests be conflicting, inconsistent, diverse, or otherwise discordant.” E. C. 5-14, 241 Ga. 689 (1978).
¶17“If a lawyer is required to decline employment or to withdraw from employment under D. R. 5-105, no partner or associate of his or his firm may accept or continue such employment.” D. R. 5-105 (D), 241 Ga. 694 (1978).
