Annie Dookhan And The Massachusetts Drug Lab Crisis

Graphic: Drug Findings Of Annie Dookhan

Data

We have records of 58,070 drug tests Annie Dookhan performed as a primary or secondary chemist during nearly a decade at the Hinton State Laboratory in Jamaica Plain, Mass. This graphic is a breakdown of her official drug findings, grouped by drug class.

Cocaine was by far the most common finding, accounting for about a third of Dookhan’s drug tests, followed by marijuana, heroin and oxycodone.

In the Commonwealth of Massachusetts, drugs are broken down into five classes from Class A drug offenses, which are the most serious, to Class E drug offenses. They include:

  • Class A Drugs – Heroin and other opiates; drugs such as Special K
  • Class B Drugs – Cocaine; prescription opiates such as Oxycontin; Ecstasy; Amphetamines; Methamphetamine; PCP or Angel Dust
  • Class C Drugs – Prescription tranquilizers and drugs such as Clonazempam, Vicodin and Valium
  • Class D Drugs – Marijuana
  • Class E Drugs – Prescription drugs not otherwise classified
