The Fair Sentencing Act of 2010 reduced the federal sentencing gap between crack cocaine and powder cocaine from 100-to-1 to 18-to-1. Signed into law on August 3, 2010, it raised the crack quantities that trigger mandatory minimum prison terms, eliminated the mandatory minimum for simple possession of crack, increased maximum fines for major traffickers, and directed the U.S. Sentencing Commission to adjust the guidelines for both aggravating and mitigating conduct.1Congress.gov. Public Law 111-220 – Fair Sentencing Act of 2010 The law reaches federal prosecutions only. It does not touch state drug statutes, and states set their own cocaine penalties independently.
The 100-to-1 Rule the Act Replaced
Under the Anti-Drug Abuse Act of 1986, one gram of crack cocaine triggered the same mandatory minimum sentence as 100 grams of powder cocaine. Five grams of crack drew a five-year mandatory minimum; so did 500 grams of powder. Fifty grams of crack drew a ten-year mandatory minimum, matching 5,000 grams of powder.2United States Sentencing Commission. The Crack Sentencing Disparity and the Road to 1:1
The 1986 Congress adopted the 100-to-1 ratio on the belief that crack was substantially more dangerous and addictive than powder. No legislative record explained the choice of that specific number. By the early 1990s, the average federal drug sentence for Black defendants was 49% longer than for white defendants, a gap driven largely by the crack rule, because crack prosecutions fell disproportionately on Black communities while powder use cut across racial lines.
The New Crack Cocaine Thresholds
The core of the 2010 law amended 21 U.S.C. § 841 to raise the crack quantities that trigger mandatory prison terms. The five-year mandatory minimum now requires at least 28 grams of crack, up from 5 grams. The ten-year mandatory minimum now requires 280 grams, up from 50.3Office of the Law Revision Counsel. 21 USC 841 – Prohibited Acts A
Powder cocaine thresholds did not move. They remain at 500 grams for the five-year mandatory minimum and 5,000 grams for the ten-year. The new ratio comes from the math: 500 divided by 28 is roughly 18.4United States Sentencing Commission. 2015 Report to the Congress – Impact of the Fair Sentencing Act of 2010 Someone caught with 30 grams of crack today faces the five-year floor rather than the ten-year floor that would have applied before August 2010. These are the numbers that govern every federal crack prosecution.
No More Mandatory Minimum for Simple Possession
Section 3 of the Act ended the mandatory minimum sentence for simple possession of crack cocaine.1Congress.gov. Public Law 111-220 – Fair Sentencing Act of 2010 Before the change, crack was the only drug in the federal system that carried a five-year automatic prison term for a first-time possession offense, treating a person with a personal-use quantity the same as someone charged with distribution.
Federal courts now sentence simple crack possession under the same rules that apply to other controlled substances: up to one year for a first offense, with escalating penalties for repeat offenders.5Office of the Law Revision Counsel. 21 USC 844 – Penalties for Simple Possession Judges can weigh probation, treatment, or shorter jail terms when the facts call for it.
Higher Fines for Trafficking Convictions
Section 4 sharply raised the maximum fines under 21 U.S.C. § 841(b). For the most serious trafficking offenses, the maximum individual fine went from $4 million to $10 million on a first offense, and from $8 million to $20 million for a repeat offender. Organizational fines climb as high as $75 million for repeat offenses. For the next tier of trafficking cases, first-offense individual fines rose from $2 million to $5 million.1Congress.gov. Public Law 111-220 – Fair Sentencing Act of 2010 These fine increases cover trafficking in any drug the statute reaches, not just cocaine.
Guideline Changes for Aggravating and Mitigating Conduct
Sections 5, 6, and 7 told the U.S. Sentencing Commission to sharpen the guidelines so that low-level participants and dangerous traffickers are treated differently.
Section 5 required at least a two-level guideline increase when a defendant used violence, made a credible threat of violence, or directed others to use violence in the course of a drug trafficking offense. Section 6 required the same two-level increase for defendants who bribed law enforcement, ran a drug house, or served as an organizer or leader in an offense involving what the statute calls super-aggravating factors: distributing drugs to minors, the elderly, or pregnant individuals; exploiting vulnerable people; importing controlled substances; intimidating witnesses; or running drug trafficking as a livelihood.6Congress.gov. S.1789 – Fair Sentencing Act of 2010 – Enrolled Text
Section 7 cut the other direction. It directed the Commission to reduce guideline penalties by at least two offense levels for defendants who played a minimal role and met other mitigating criteria.7U.S. Department of Justice. The Fair Sentencing Act of 2010 The idea was to give judges a cleaner way to separate a courier with no authority from the person who recruited them.
Retroactivity for Pre-2010 Sentences
As originally enacted, the Fair Sentencing Act applied only to defendants sentenced after August 3, 2010. Anyone sentenced under the old 100-to-1 rules before that date could not use it to seek relief.
That changed with the First Step Act of 2018. Section 404 made the Fair Sentencing Act retroactive. A person sentenced before August 3, 2010, for a crack cocaine offense whose statutory penalties were altered by Sections 2 or 3 of the 2010 law can now ask a federal court to impose a reduced sentence as if the 2010 thresholds had been in place all along.8Congress.gov. Public Law 115-391 – First Step Act of 2018 The motion can come from the defendant, the Bureau of Prisons, the government’s attorney, or the court itself.9United States Sentencing Commission. Retroactivity Data Report on Section 404 of the First Step Act of 2018
Two limits apply. A court will not consider a Section 404 motion if the sentence was already imposed or reduced under the Fair Sentencing Act’s amendments, or if a prior Section 404 motion was denied on the merits after a full review. Eligibility does not guarantee relief; the court can still deny a reduction.8Congress.gov. Public Law 115-391 – First Step Act of 2018 Sentencing Commission data show about 4,000 people received reduced sentences under Section 404, with release dates moving forward by roughly 72 months on average.
What the Act Did Not Do
The 2010 law narrowed the crack-to-powder ratio; it did not eliminate it. At 18-to-1, crack still triggers mandatory minimums at a fraction of the quantity required for powder. The EQUAL Act, introduced in multiple sessions of Congress, would set the ratio at 1-to-1 by equalizing the thresholds. It was referred to committee in the 118th Congress but did not advance to a vote.10Congress.gov. H.R. 1062 – EQUAL Act Until Congress passes new legislation, the 18-to-1 ratio is the federal rule.
