1. The sample - Notes
- A selected nominee was later asked in one of the first
questions if he or she had used cocaine more than 25 times. If the answer
was `no' the interview had to be stopped. This was never necessary.
- In a household survey in Amsterdam of the population
of 12 years and older, current use of cocaine in the age cohort under
20 years of age appeared to be less than 0.5% (). This explains the
difficulty of finding experienced cocaine users in this age cohort by
our field workers.
- This assumption is quite arbitrary. It saves us from
the problem of including experimental users of cocaine of a long time
ago in the reference group from the household survey. It does not save
us from including experimental users from a short time ago! This comparison
should be considered as a rough tool, but there is at least some possibility
to check our snowball sample against another (independent) sample.
- In the Dutch school system, children go to elementary
school from 4-12 years of age (LO). After that, there is a differentiated
and rather complicated system of various branches and levels. The lowest
level of the technical branch is called is the 4-year LBO (Lower Profession
Education, e.g. plumber) and is the lowest level of the technical branch,
followed by a 3-year MBO (Middle Profession Education, e.g. nurse) and
a 4-year HBO (Higher Profession Education; e.g. social worker, engineer).
The basic level of the more general branch starts with the 4-year Mavo
at the lowest level, the 5-year Havo at medium level and the 6-year
Atheneum or Gymnasium at the highest level. Only the last two schools
prepare for University. Many courses run at American universities, are
not taught at Dutch universities, but at MBO and HBO level.
- The word 'risky' was offered to our respondents, without
any specification. If respondents would count nominees as risky users
or not was purely a subjective matter.
