3. Level of use through time - Notes
- Personal communication from Erickson.
- Chitwood's cut-off points as quoted above are the
ones he mentions in his article "Patterns and Consequences of
Cocaine Use" (1985). These cut-off points, however, do not
cover the whole variety of patterns of cocaine use. Morningstar and
Chitwood (1983) developed a thirteen point scale, containing dosage,
frequency and route of ingestion, which does cover all the possible
varieties of cocaine use. The cut-off points in Chitwoods 1985 article
are a summary of this scale. In Table 3.5.a the thirteen point scale
has been used.
- In this Table L, M, H and O stand for Low, Medium,
High and Zero Use. So LLO means Low in first year, Low in top period,
Zero use at last 3 months. Etcetera.
Unfortunately we didn't ask the respondents who hadn't used cocaine
during the last three months, when was the last occasion when they did
use. For these respondents we couldn't assess exactly the length of
their cocaine using career, but we approximated this by supposing their
last occasion wasn't longer than one year ago. In Table 3.5.c these
respondents' estimates are accompanied by a question-mark.
