Two capture??recapture methods w er e used to estimate the numbers of drug addicts. Random stratified sampling survey was used to verify the optimum allocation.The first captur e??r ecaptur e method ( CR1 ) referred to the number from optimum allocation random stratified sampling survey conducted in the communities and the number from local Public Security Bureau list being the second capture. The second capture??recapture method ( CR2) referred to the collection of records in t he detoxification unit with an interval of 4 months.

When the figure 1.73% was applied to the total population ( 72709) in Hong jiang, the resulty ielded an estimation of 1258 drug addicts.
