Results are presented from a survey in which a sample of 887 people living in southern Ghana were questioned as to the chewing sticks they use, reasons for choice, and whether sticks are collected or bought. It appears that four kinds of sticks account for more than 85% of the total usage. Differences were recorded in preferred species and in diversity of species used, reason for choice and source of supply, according to age, sex, ethnic origin, size of settlement and educational background.
