Drug Alerts

Information for Cocaine and Crack users:

Over 90% of recently tested Cocaine and Crack now contain Levamisole.

What is it?
Most current commercial preparations of Levamisole are intended for veterinary use as a dewormer in cattle, pigs, and sheep. Its also used by aquarists as an effective treatment for Camallanus roundworm infestations in freshwater tropical fish.

What is the potential harm?
One of the more serious side effects of levamisole is agranulocytosis, or the depletion of the white blood cells. In particular, neutrophils appear to be affected the most.

There have also been reports of levamisole induced necrosis syndrome in which erythematous painful papules can appear almost anywhere on skin.

This adverse effect has been observed in several cocaine users in the South Gloucestershire area. It appears some people are more susceptible to it than others, but the mechanism behind this is unclear.

Why is it used?

  • Something about the chemical structure of levamisole retains the iridescent fish-scale sheen of pure cocaine, according to a chemist with ties to the cocaine trade, giving cocaine cut with levamisole the same appearance as pure cocaine.
  • Levamisole is a bulking agent for crack. The process of making crack involves “washing” cocaine and filtering out impurities and cutting agents. Levamisole slips through this process, meaning you can produce more volume of crack with less pure cocaine.
  • Levamisole passes the “bleach test,” a simple street test used to detect impurities in cocaine.
  • Levasmisole also adds a ‘speedy’ effect to cocaine – making it appear to be better quality.


We are now working in partnership with the University of the West of England to offer an on-campus support service for students who are experiencing issues with drug and/or alcohol use.

El, our UWE Drug and Alcohol Practitioner, is based with the Wellbeing Team on Frenchay Campus. However, you don’t need to be working with Wellbeing to access support.

Although we are working jointly with the university, our confidentiality policy still stands – you do not need to worry about information being shared with the university without your consent, unless it is essential to do so to protect you or someone else from serious harm.
