Annual Numbers of New Users of Marijuana: 1965-2002
This figure is a line graph, where the horizontal axis
represents year, and the vertical axis represents the
number of new users, in thousands. There are three lines
on the graph corresponding to three age categories: All
Ages, Under Age 18, and Age 18 or Older.
In 1965, there were 794,000 new marijuana users of all
ages. This increased to a peak of 3.5 million in 1973,
and then gradually decreased to 1.5 million in 1990.
The number of new users increased to 2.7 million in
1995, and remained fairly stable through 2002, when the
number of new marijuana users was 2.6 million. The number
of new marijuana users under age 18 in 1965 was 304,000.
This increased to 1.9 million in 1974, where the number
of new marijuana users stayed fairly stable until it
started decreasing again in 1979. In 1990, the number
of new marijuana users under age 18 decreased to 825,000,
but increased again to a peak in 2000 of 2.0 million.
The number of new users dropped to 1.8 million in 2002.
The number of new marijuana users age 18 or older increased
from 490,000 in 1965 to 1.6 million in 1969, and then
peaked at 1.7 million in 1973. There was a fairly steady
decline of new adult marijuana users until 1988, when
the number was 608,000. The number of new users only
moderately increased between then and 2002, when there
were 810,000 new users.
