Alert - contamination of herbal or �skunk-type� cannabis with glass beads
1. The Department of Health has recently received information suggesting that batches of herbal and �skunk-type� cannabis have been contaminated with microscopic glass-like beads (or possibly ground glass). Laboratory testing has since confirmed a number of cases from a number of different parts of the country, in which cannabis appears to contain microscopic particles of glass. We have no information on other types of cannabis such as resin.
2. Reports, unconfirmed, suggest that smoking this contaminated cannabis, has been linked with complaints by users of sore mouth, mouth ulcers, chesty persistent coughs, and a tight chest lasting a few days after use.
3. Government advice already makes clear that cannabis is a substance harmful to health. The risk of glass contamination adds an additional layer of risk of harm. Whilst the exact potential health harm from this contamination is not yet fully determined, inhaling hot glass into the mouth, throat, or into the lungs should clearly be avoided.
4. In the current circumstances, the Department of Health advises that smokers of herbal and 'skunk-type' cannabis, in particular, should exercise caution.
5. For any patients presenting with concerns about their health after having smoked cannabis which may have been contaminated, or who may benefit from opportunistic health advice due to an identified high risk of cannabis use, the following advice may be useful:
