Common cocaine additives include:
These all come in a white powder form that is visually indistinguishable from the standard form of street cocaine. They are not particularly dangerous but also not something you would generally want in your body. Small particles in laundry detergent can build up in arteries and cause dangerous blockages in the heart, brain, or liver.
In addition to cutting cocaine to make it more profitable, the substance may be altered in order to change it into different forms. Freebase cocaine is made to be easy to smoke through the use of ammonia and ether.
If not prepared carefully, the ether in freebase cocaine can actually cause burns in a person’s throat and nasal passages. This form of cocaine is also considered to be more addictive.
In addition to the more common fillers, dealers have been known to cut cocaine with much more dangerous substances in an attempt to make the most profit. For example, it was discovered in 2005 that 2 percent of all the cocaine seized by the US Drug Enforcement Administration (DEA) was cut with levamisole, a cattle dewormer. This drug used to be used for humans infected with parasitic worms but was found to severely deplete white blood cells. By 2011, 73 percent of all the cocaine tested by the DEA contained levamisole.
