CONTAMINATED CANNABIS WARNING : January 2007
|
In July of 2006, users of ‘skunk’ cannabis started to report finding some kind of grit or sand coating the cannabis buds they were buying. Reports of this contamination are now coming from all areas of the UK, with many users reporting sore throats, mouth ulcers and chest pains from its use.
The contamination has been found to be silica beads used as a reflective substance in road marking paint, and for sandblasting. The beads, which measure from 10-100 microns in diameter, appear to have been sprayed on to the cannabis plants during growth.
Unless examined carefully, the beads look like the THC crystals usually visible on the surface of skunk cannabis buds. Upon closer analysis, the contaminated cannabis is apparently low quality, and does not have the THC crystals that are usually present.
The source of the contamination is unknown, although reports from across Europe of this kind of contamination are reaching the UK in increasing frequency.
The contaminant has the potential to cause damage to the lungs, particularly through prolonged exposure. Effects from the inhalation of the particles over time, when used in industry, are thought to be similar to Asbestosis. The particles do not melt, and it is believed they can pass into the lungs as the cannabis is smoked.
As of yet the bonding agent, to which the beads are added before spraying onto the cannabis, is unknown. This is also a concern, as the potential effects on health from smoking these bonding agents are unknown.
Many users are putting a small amount of the ‘grit’ between their teeth to identify if it is the contaminant. The ‘grit’ will feel like sand if rubbed between the teeth.
We are advising that users do not buy or use this contaminated cannabis, due to the severe risks that it poses to health. |
