Some substances used to cut illicit drugs can be fairly harmless while others can be quite dangerous. This section will go over some of the dangers associated with various cutting agents.
Levamisole:
Levamisole, which is found in an increasingly large number of illicit cocaine samples over the recent years, is a substance that can lower a persons white blood cell count, making them more prone to bacterial infections. These bacterial infections can become deadly if the person effected does not seek proper medical treatment. One article, put out by the Harm Reduction Journal, examined 42 cases of Neutropenia (lower number of neutrophils which make up 50-70% of a persons white blood cells) from cocaine tainted with levamisole between Jan. 1 2008 and March 31 2009 in Alberta and British Columbia, Canada. (Ref #1) In 2009, the U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) made an announcement that over 70% of the cocaine, analyzed by the DEA, in the U.S. was tainted with this substance. (Ref #2)
Symptoms of Neutropenia that are caused by a weakened immune system include; infections throughout the body, high fever, chills, swollen glands, painful sores, and wounds that won't heal. If detected and diagnosed properly it can be treated, but untreated may lead to death. (Ref #3)
BZP, BenzylPiperazine:
BZP is most often found in Ecstasy pills (with or without MDMA) and sometimes used to cut MDMA. Many times TFMPP will be used in conjunction with BZP in order to produce MDMA-like effects. BZP has been known to produce negative effects in those who consume products containing it, particularly when used with MDMA. The following symptoms have been reported from users of this substance; agitiation, tachycardia, palpitations, seizures, collapse, anxiety, confusion, vomiting, and headache. These symptoms can last for up to, and possibly over, 24hrs. The most common of these symptoms reported were palpitations, vomiting, and agitation. (Ref #4)
This information is based on a study done in New Zealand on emergency admissions related to party pills between April and September of 2005, with 61 patients on 80 occasions. The most worrying information is in regards to the seizures, which 14 patients had (grand mal), although their average pill intake was the same as those who didn't. (Average pill intake of seizing patients 4.3, average of non-seizing 4.55) It should be noted that only a small portion of these cases were confirmed by toxicological analysis. (Ref #4)
