Botulism in patients who inhale cocaine: the first cases in France.

We describe 2 cases of mild botulism in patients who inhaled cocaine. Botulism, though rare, is increasing in incidence among illicit drug users.

Clinicians should be aware of this phenomenon; botulism should be considered in illicit drug users with neurological symptoms.
