They usually affiliate with these gangs for protection from other inmates or for control of certain criminal activities in the prison. In Oakland, the majority of the dosage-unit sales of cocaine are in crack form. About 75 percent of the crack is sold on the street, the remainder from stash houses or other residences. In Richmond, dosage units of powdered cocaine and crack are sold on the street and from houses and apartments. In the North Bay area and Santa Rosa, powdered cocaine is the predominant form of the drug.
Recent trends indicate that Hispanic distribution groups sell it from stash houses.
In the Sacramento area, African-American gangs such as the Oak Park Bloods and 29th Street Crips convert powdered cocaine into crack and sell it primarily out of houses or cars. The 29th Street Crips produce inexpensive yet high-quality crack. The gang is currently attempting to become the dominant crack distributor in the Sacramento area. African-American distributors dominate the retail crack trade in Fresno. In some areas, particularly West Fresno, dealers are territorial and will resort to violence to protect their turf.
