Acute (upper row) and chronic (after 6 months) effects following heroin inhalation (chasing the dragon). Acute (upper row) and chronic (after 6 months) effects following heroin inhalation (chasing the dragon). In the acute phase, a diffuse edematous swelling of the white matter is present both supra- and infratentorially. On follow-up after 6 months, the patient demonstrated mental retardation and persistent psychosis. CT demonstrates bilateral degeneration of the white matter with concomitant widening of the ventricles. S. Geibprasert et al.
