called "grit weed"
Drug campaigners have warned that a batch of cannabis adulterated with tiny glass beads which they say could pose a risk to health has flooded the UK market. Anecdotal reports suggest it is being sold in almost every part of the country.
The charity Drugscope is issuing a warning. "We want to make people aware of it from a public health point of view. If you are smoking this stuff and taking it into your lungs it's not good news."
The fact that "grit weed", as it is being called, is so widespread suggests that contamination is happening at an early stage in the production process. "It seems to be being done on an industrial scale," said Harry Shapiro of Drugscope.
The dealers' motivation seems to be to bump up the weight of their product. They appear to be doing this by spraying plants with the reflective element from the paint used on road lines. The tiny reflective glass beads become imbedded in the leaves.
"It looks perfectly normal. In fact it looks good quality," said Derek Williams of UK Cannabis Internet Activists, which campaigns against cannabis prohibition.
