More signs of disarray in closed state drug lab

State investigators have found at least a half-dozen drug samples scattered about the state lab in Jamaica Plain, documents show, raising questions about the integrity of all testing where indicted state chemist Annie Dookhan worked.

Investigators for the state ­inspector general, who have been combing through the closed lab for months, found a plastic bag containing “a white rock substance” and test tubes “containing unknown substances” in one supervisor’s ­office. They found pills taped to a lab bench cabinet and old samples, including marijuana submitted in 1996.
