Tables 3.6 and 3.7 present lifetime and
past month data on how many days respondents used marijuana. There was
some variation in the number of drugs used during one's lifetime, according
to age, that most likely reflects the adult groups' having more lifetime
opportunities to use. Of the lifetime users, over half had used marijuana
on 12 days or more in their lifetime, and 29% had used it on more than
100 days (Table 3.6). Among current marijuana users, almost one-fourth
(24%) reported using marijuana on an almost daily basis (i.e., on 20 to
30 days in the past month) (Table 3.7). Among those aged 12 to 17 and 18
to 25, the percentage of past month users who reported using on an almost
daily basis increased substantially since 1994. Among 12 to 17 year olds,
it increased from 11% in 1994 to 21% in 1997 and, among 18 to 25 year olds,
from 20% to 27% (OAS, 1996a, Table 3.7).
