Cocaine: Both cocaine and crack are widely available in Wisconsin. Cocaine is transported into the state by Mexican drug trafficking organizations. These organizations transport large shipments of cocaine from the Southwest Border either through Chicago or to Milwaukee directly, concealed within shipments of legitimate goods in tractor-trailers. These Mexican organizations also are the primary wholesale distributors ofcocaine and supply African-American and Hispanic street gangs that control the retail distribution of crack throughout the state. DEA Milwaukee and the DEA Madison report that cocaine is readily available in multi-kilogram quantities. DEA Green Bay reports that cocaine is readily available in multi-ounce to kilogram quantities.

Heroin: The Milwaukee County Medical Examiner's Office records show that heroin abuse has stabilized in Wisconsin over the past two years. That office listed 12 heroin-related deaths in 1999, 26 in 2000, and 11 in 2001. Approximately three-fourths of all reported heroin-related deaths in Wisconsin occurred in Milwaukee. Most heroin use is concentrated in the Milwaukee and Racine areas. Rising levels of purity, some measured as high as 95 percent give users the option of snorting the drug rather than injecting, an option that may appeal to younger users. DEA Milwaukee reports that Southeast Asian heroin, trafficked by Nigerian criminal groups, is the predominant type available. A recent DEA Milwaukee investigation resulted in the seizure of 2.3 kilograms of Southwest Asian heroin, the largest seizure of heroin in Wisconsin history. The seizure resulted in the arrest of multiple Nigerian defendants. The office further reports that Southwest Asian heroin has not been encountered in the Milwaukee area. South American heroin is distributed by Dominican traffickers. The availability of brown heroin remains low, and black tar heroin is rare in Milwaukee.

Methamphetamine: Methamphetamine production and abuse are expanding from Minnesota and Iowa into rural counties in western Wisconsin. To a lesser extent, some methamphetamine is imported into the state by Mexican sources from the Southwest Border. According to the El Paso Intelligence Center, federal, state, and local law enforcement agencies in Wisconsin reported 78 methamphetamine-related incidents involving the seizure of clandestine laboratories, dumpsites, or chemicals, glassware, and equipment during 2002, while no such incidents were reported during 1997. DEA Milwaukee has not observed a significant increase in distribution or use of methamphetamine. DEA Green Bay reports that there is limited availability of methamphetamine in its area, as most is produced locally by small clandestine laboratories. However, a recent seizure of 37 pounds of methamphetamine was made from out of state individuals, who were attempting to create a market in the Green Bay area. DEA Madison reports that methamphetamine is readily available in ounce quantities in northwestern Wisconsin, supplied by sources from Minneapolis.

Club Drugs: "Club drugs" and "designer drugs" are general terms for synthetic chemical drugs that have become popular with teenagers and young adults. These drugs include MDMA (Ecstasy), Ketamine, GHB, GBL, and LSD. According to a recent drug price survey in Wisconsin, most of the law enforcement agencies that responded indicated that club drugs were available in their jurisdictions, albeit at low levels. The DEA has reported encounters with Ketamine in Milwaukee and Madison, and with GHB in Green Bay, Wisconsin.

Marijuana: Marijuana remains the most readily available and most widely used drug in Wisconsin. Milwaukee and Madison are both major destinations for Mexico-produced marijuana and transshipment points to other areas in the state. This is augmented by local cultivation. Sixty percent of prison inmates test positive for marijuana when entering correctional institutions. Wisconsin authorities further report that one-fourth of all marijuana users also use other drugs. DEA Milwaukee, Madison, and Green Bay report that marijuana is readily available in multi-kilogram quantities.

Other Drugs: The use of diverted controlled substances in Wisconsin continues to be a problem. The most commonly diverted controlled substances from the licit market are ritalin, vicodin, hydrocodone, and other hydrocodone products, oxycontin, and other oxycodone products, and the benzodiazepines.
