Mr Carter added there was good evidence that IDUs can do very well on anti-HIV treatment - but often stigma and discrimination meant that they were denied potentially life-saving drugs. | Mr Carter added there was good evidence that IDUs can do very well on anti-HIV treatment - but often stigma and discrimination meant that they were denied potentially life-saving drugs. |
