MEMORANDUM**


2
Jose Mesa Ayala appeals his sentence, imposed under the United States Sentencing Guidelines (Guidelines), following his plea of guilty to distributing over 500 grams of cocaine and 75 grams of heroin in violation of 21 U.S.C. § 841(a)(1).   Ayala claims, first, that his prosecution by federal, rather than state, authorities violated due process;  and, second, that his 78-month sentence constitutes cruel and unusual punishment in violation of the eighth amendment.   We have jurisdiction under 28 U.S.C. § 1291 and we affirm.


3
Cooperation between state and federal authorities to suppress the trafficking and abuse of controlled substances does not violate due process.   United States v. Figueroa-Soto, 938 F.2d 1015, 1020 (9th Cir.1991), cert. denied, 112 S.Ct. 1181 (1992).   Absent proof of illegal discrimination in a state's decision to refer a defendant for federal prosecution, we may not review the charging decision.   United States v. Nance, 962 F.2d 860, 865 (9th Cir.1992) (per curiam).


4
The statutory imposition of penalties according to quantity rather than purity of narcotics does not violate the eighth amendment or the due process clause.   Harmelin v. Michigan, 111 S.Ct. 2680 (1991);   United States v. Klein, 860 F.2d 1489, 1500 (9th Cir.1988) (analyzing 21 U.S.C. § 841)..   A constitutional sentence within the Guidelines range cannot be reviewed.   United States v. Corley, 909 F.2d 359 (9th Cir.1990).


5
Here, Ayala pleaded guilty to two federal crimes, each of which exposed him to a possible sentence under the Guidelines of 78-97 months' imprisonment.   The district court sentenced him to concurrent terms of 78 months.   Ayala has not raised a claim of discrimination based on a suspect characteristic, nor shown that the district court's sentence was unconstitutional.   Accordingly, we decline to review either claim he raises, and we uphold his sentence.


6
AFFIRMED.
