Ask a chemist the difference between cocaine and crack, you’ll likely hear about acid-base chemistry. Ask the other type of chemist and you’ll likely hear “about 5 years”. It is mainly the sentencing differences, rather than the chemical differences, that dominate discussions on cocaine and crack. Those sentencing differences were kicked-off by The Anti-Drug Abuse Act of 1986 (eventually Public Law No: 99-570), which resulted in vastly different mandatory sentences for federal cocaine versus crack crimes (US Code § 841).
How different? It took 500 grams of cocaine to get a nickel in the Big House, but only took 5 grams of crack to land you in the clink for the same time (see A, B & C). Clearly, it was legally advantageous to do and deal in blow rather than rocks. Based on this 100-to-1 sentencing difference, belies how chemically similar these compounds are.
Cocaine is often thought of as that white powder Scarface planted his face in (Figure 2). That powder is actually cocaine hydrochloride (chemical formula [C17H22NO4]+ Cl-), a salt of the alkaloid compound cocaine (Figure 1).
Crack, however, seems made for smoking with a mp* of 96-97 C. Crack is easily prepared by heating an aqueous solution of cocaine hydrochloride and the base sodium bicarbonate (baking soda), then collecting the precipitate. So... crack is cocaine and what we think of as cocaine is actually cocaine salt. Oh, and freebase is also cocaine. Freebase cocaine is prepared much the same way as crack, swapping ammonia for baking soda, with the additional steps of ether extraction to yield ‘freebase’. Like crack, freebase is typically smoked. While cocaine hydrocloride has that powdery appearance (Figure 3A), crack and freebase look like rocks (Figure 3B).
While members of the US Congress likely tossed around the words 'coke', 'crack' and 'freebase' during floor debates, hearings, committee meetings and whatever else occurred to bring us Public Law No: 99-570, you won't find those words in US Code § 841 (excerpt below).
(B) In the case of a violation of subsection (a) of this section involving—. . .
- (i) 100 grams or more of a mixture or substance containing a detectable amount of heroin;
- (ii) 500 grams or more of a mixture or substance containing a detectable amount of—
- (I) coca leaves, except coca leaves and extracts of coca leaves from which cocaine, ecgonine, and derivatives of ecgonine or their salts have been removed;
- (II) cocaine, its salts, optical and geometric isomers, and salts of isomers;
- (III) ecgonine, its derivatives, their salts, isomers, and salts of isomers; or
- (IV) any compound, mixture, or preparation which contains any quantity of any of the substances referred to in subclauses (I) through (III);
(iii) 5 grams or more of a mixture or substance described in clause (ii) which contains cocaine base;
such person shall be sentenced to a term of imprisonment which may not be less than 5 years...
In US Code § 841, cocaine hydrochloride fell under (B) (ii), crack under (B) (iii) as “cocaine base”, and the disparate sentences came under attack. What was the motivation for 100-10-1 sentencing difference? Race, pharmacological differences, drug war politics, some or none of the above? This disparity debate bounced around the country and returned to the US Congress in 2009 with the introduction of the Fair Sentencing Act.
Various individuals and groups showed their varying-levels of support (see D, E, F & G) for this act. Why the varying levels of support? The Fair Sentencing Act didn't make the sentences equal. Instead of a 100-to-1 difference in sentencing, it was now a (roughly) 18-to-1 difference. As of August 2010, when the Fair Sentencing Act became law , 500 grams of cocaine or 28 grams of crack will get you five in the joint.
Actually, if we're being specific, 28 grams of "cocaine base" will get you a nickel. By now, it seemed clear that "cocaine base", though redundant, includes crack, freebase and anything else with cocaine (Figure 1) in it. Not so, argued Frantz DePierre.
In 2005, DePierre got caught selling drugs and charged with distributing 50 grams or more of "cocaine base". Now DePierre didn't try to argue that the stuff he was caught selling was cocaine hydrochloride, thus lessening any possible prison time. Let's face it, that argument would have been absurd. No, DePierre argued that "cocaine base" was crack - and only crack.
DePierre asked the District Court to instruct the jury that, in order to find him guilty of distribution of cocaine base, it must find that his offense involved “the form of cocaine base known as crack cocaine.” App. in No. 08–2101 (CA1), p. 43. His proposed jury instruction defined “crack” identically to the Guidelines definition. See id. , at 43–44; see also USSG §2D1.1(c), n. (D). In addition, De-Pierre asked the court to instruct the jury that “hemi-cal analysis cannot establish a substance as crack because crack is chemically identical to other forms of cocaine base, although it can reveal the presence of sodium bicarbonate, which is usually used in the processing of crack.” App. in No. 08–2101, at 44. [excerpt^ from Franz DePierre v. United States]
You can almost see DePierre's (or his lawyer's) train of thought... "If the court says "cocaine base" is only crack, but chemical analysis can't tell crack from freebase from other stuff with cocaine in it, then I've got a get out of jail free card."
Well, the District court didn't do as DePierre requested.
Instead, the District Court told the jury "..the statute that’s relevant asks about cocaine base. Crack cocaine is a form of cocaine base, so you’ll tell us whether or not what was involved is cocaine base … ”.
During DePierre's trial, a government chemist testified that the drug DePierre was caught selling was "cocaine base" and that no sodium bicarbonate was identified. DePierre was convicted and he took his argument to the next level, i.e. the United States Court of Appeals for the First Circuit (CA1). The CA1 sided with the District Court and...
...reject[ed] DePierre’s argument that §841(b)(1)(A)(iii) should be read only to apply to offenses involving crack cocaine....holding that “ ‘cocaine base’ refers to ‘all forms of cocaine base, including but not limited to crack cocaine.’ ” Id. , at 30–31 (quoting United States v. Anderson , 452 F. 3d 66, 86–87 (CA1 2006)). [excerpt from Franz DePierre v. United States]
Essentially, CA1 takes "cocaine base" in US Code § 841 to mean the alkaloid compound cocaine (Figure 1) and stuff containing said alkaloid (e.g. crack, freebase, coca paste). Once again, DePierre took it to the next level and Supreme Court of the United States (SCOTUS) granted certiorari "..to resolve the longstanding division in authority among the Courts of Appeals on this question."
To SCOTUS, DePierre made 5 arguments “...that the term ‘cocaine base’ in clause (iii) is best read to mean ‘crack cocaine.’ SCOTUS was not convinced by any of them. Sure, SCOTUS agreed that ‘cocaine base’ was redundant, discussed how the language of the law could be fixed, and what Congress could have meant by "cocaine base", but in the end…
That we may rue inartful legislative drafting, however, does not excuse us from the responsibility of construing a statute as faithfully as possible to its actual text. 11 And as noted earlier, there is no textual support for DePierre’s interpretation of “cocaine base” to mean “crack cocaine.” [excerpt from Franz DePierre v. United States]
“Textual support”? SCOTUS seems to mean that since "cocaine base" not "crack cocaine" appears in the relevant statue(s) and congressional records, ‘cocaine base’ isn’t only crack. Plus, it appears that SCOTUS found that swapping "crack cocaine" for "cocaine base" made no sense in some sections of the relevant statue.
We agree with the Government that the most natural reading of the term “cocaine base” is “cocaine in its base form”— i.e. , C 17 H 21 NO 4 , the molecule found in crack cocaine, freebase, and coca paste. On its plain terms, then, “cocaine base” reaches more broadly than just crack cocaine. [excerpt from Franz DePierre v. United States]
SCOTUS’ final word?
We hold that the term “cocaine base” as used in §841(b)(1) means not just “crack cocaine,” but cocaine in its chemically basic form. We therefore affirm the judgment of the Court of Appeals.
It is so ordered.
What does this mean for cocaine hydrochloride? Absolutely nothing, it’s not a “cocaine base” – something SCOTUS states at the start of its opinion.
Chemically, therefore, there is no difference between the cocaine in coca paste, crack cocaine, and freebase—all are cocaine in its base form. On the other hand, cocaine in its base form and in its salt form (i.e. , cocaine hydrochloride) are chemically different, though they have the same active ingredient and produce the same physiological and psychotropic effects. See id. , at 14–22. The key difference between them is the method by which they generally enter the body; smoking cocaine in its base form—whether as coca paste, freebase, or crack cocaine—allows the body to absorb the active ingredient quickly, thereby producing a shorter, more intense high than obtained from insufflating cocaine hydrochloride. [excerpt from Franz DePierre v. United States]
So where are we at now? An 18-to-1 sentencing difference between cocaine hydrochloride and “cocaine base” crimes, with “cocaine base” not limited to crack. In Franz DePierre v. United States, SCOTUS did not directly address the validity of cocaine hydrochloride and “cocaine base” sentencing differences. If anything, SCOTUS seemed to say “Congress had its reasons and it’s up to Congress to deal with it" - but, I'm no legal scholar (though I did watch Law & Order for 20 years). Nope, I'm just a chemist happy to see little chemistry in the courts.
