Fentanyl Analogue Sentence Calculator

Analogues such as carfentanil, acetylfentanyl and furanylfentanyl are counted at four times the weight of fentanyl itself. The minimums start at just 10 grams. In federal court, 10 g triggers a 5-year mandatory minimum and 100 g triggers 10 years.

“No criminal history points, early plea” assumes zero criminal history points, no weapon, no violence and no leadership role, so the plea reduction and the 2-level zero-point reduction both apply. The mandatory minimum column assumes no prior serious drug felony or serious violent felony; the safety valve can remove it.

What to know

  • Whether a substance legally counts as a fentanyl analogue can itself be disputed in court.

Frequently asked questions

What amount of fentanyl analogue triggers a federal mandatory minimum?

10 g of fentanyl analogue triggers a 5-year mandatory minimum, and 100 g triggers 10 years (21 U.S.C. §841(b)(1)), for someone without a prior serious drug felony or serious violent felony.

What is the guideline sentence for 20 g of fentanyl analogue?

The Drug Quantity Table puts 20 g at level 24. For someone with no criminal history points who pleads guilty, with no weapon, violence or leadership role, the guideline sentence is 60 months, driven by the 5-year minimum. With the safety valve it is 24–30 months.

Does the weight include the packaging or cutting agents?

Packaging, no. Cutting agents, yes: the weight is the entire mixture or substance containing a detectable amount of the drug, except for drugs the table measures by purity.
