5. Routes of ingestion - Notes
- Quality of cocaine will be discussed in chapter 11.
- In the following subtables we will include the proportions
of missing values. The sometimes high values for `missing' are probably
caused by interviewer error. Instead of using the category 'don't know'
some interviewers omitted to fill in a code. Because we cannot be sure
if this omission really represents a 'don't know' we give the known
proportions of 'don't know' plus the missing values.
