delivered the opinion of the Court.
This appeal was taken after the defendant was convicted of violating C.R.S. 1963, 48-5-20, salе of a narcotic drug. 1 It is undisputed that a sale occurred. The issues are (1) whether thе substance sold was the alleged narcotic drug — “cocaine” — within the meaning of the statute, and (2) whether the statute is defective because of an unconstitutional dеlegation of legislative power.
A prosecution expert testified that the substance which he tested contained a certain percentage of cоcaine. On cross-examination, the expert testified that “pseudococаine” — a chemically distinct stereoisomer of natural cocaine — would test exactly the same as natural cocaine. He also admitted that he was not able to provide an opinion as to whether the substance which he tested was dеrived from the coca leaf, and that the test which he performed did not indicate whether the substance was a natural *118 extract of the coca leaf or synthetically produced. On the basis of the admissions made in the course of cross-exаmination, defense counsel objected to the admission of the narcotic exhibits, asserting that a proper foundation was not laid. The court overruled the objection, and at the conclusion of all of the evidence found the defendant guilty аs charged. We affirm.

Identity of the Drug
Section 12-22-301(16), C.R.S. 1973, defines “narcotic drugs” as, inter alia, “any other drug to which the federal ’Controlled Substances Act of 1970’ may apply . . . .” 2 The Federal Controlled Substances Act, 21 U.S.C. 802 (16) (1970), became effective on October 27, 1970. It provides:
“The term ‘narcоtic drug’ means any of the following, whether produced directly by extraction from substanсes of vegetable origin, or independently by means of chemical synthesis, or by a combination of extraction and chemical synthesis:
“(A) Opium, coca leaves, and opiates.” (Emphasis added.)
Although evidence of the identity of the substance which prоvided the foundation for the defendant’s conviction was ambivalent as to whether thе cocaine was “natural” or “synthetically produced,” we find no error. The United States Court of Appeals for the Tenth Circuit recently held that even if a substance in issue was “pseudococaine,” it, nonetheless, fell within the prohibition of the federal statute.

Wilburn,

Constitutionality of the Statute
It is apparent from the chronology behind the adoption of the federal and Colorado statutes that synthеtic cocaine was a prohibited substance under the Federal Act at the time the Colorado General Assembly enacted the narcotic statute which prohibits the sale of cocaine. It is conceded that a majority of the jurisdictions whiсh have considered the matter recognize that a legislature may incorpоrate in a state statute federal statutory provisions by an appropriatе reference.
See, e.g., State v. Welch,
The defendant also attacks the Colorado statute as facially invalid on the grоund that it incorporates
prospective
or
future
determinations of illegal substances under the Federal Cоntrolled Substances Act. Several courts have held similar statutory features to be constitutionally defective.
See, e.g., People
v.
Downes, supra; State
v.
Workman, supra; State
v.
Julson, supra; State
v.
Johnson,
Accordingly, we affirm.
