Answer

Patients may have sores or linear excoriations; crack pipe burns of the fingers or thumbs; thermal burns of the face and upper airway; and redness, swelling, and tenderness (secondary to phlebitis, vasculitis, cellulitis, and abscess formation).

Search for track marks in the usual sites, such as the antecubital fossae, and unusual sites, such as under the tongue and on top of the feet.

Excoriations from pruritus or scratching in response to hallucinations of crawling insects associated with cocaine use may also be found.
