 | The B.C. Centre on Substance Use says fentanyl cut with caffeine and a sugar substitute is being sold as heroin on Vancouver's streets. Testing showed that heroin was present in just 13% of samples brought in by people who thought they had bought the drug.
Overall, 61% of the substances tested at two supervised consumption sites didn't contain any of the drug that people had expected. Experts say the heroin supply has largely been supplanted. |  Fentanyl was found to be present in 88% of all the opioid samples submitted for testing. |
