Restricted Activity Days and other Problems Associated With Use of Marijuana or Cocaine Among 18 to 44 Year Olds: United States, 1991

Advance Data 246.  The primary goals of this report are to briefly discuss the relationship between restricted activity (RA) days and use of cocaine and marijuana, present data on problems and drug-related behaviors associated with cocaine and marijuana dependence and abuse, and provide documentation of the methodology of the National Health Interview Survey Drug and Alcohol Use Survey.

Data Highlights:

Among persons aged 18 to 44 years, use of cocaine, whether during the year prior to the interview or in the more distant past, is associated with a greater likelihood of having RA days.

A large percent (26.7) of past year marijuana users responded positively to a question about being high on at least one occasion while at home caring for their family. A greater proportion of men (29.3) responded positively to this question compared with women (22.0).

Overall, 45.9 percent of the past year marijuana users reported driving under the influence of this drug. Males were much more likely than females to report this problem behavior (51.0 percent of male users compared with 36.4 percent of female users).

Driving a car, at least once in the past year, within an hour after using cocaine was reported by 43.5 percent of past year cocaine users. Male users were more likely than female users (49.2 percent versus 29. 1 percent, respectively) to have driven after using cocaine.

Over one-sixth (17.2 percent) of the past year cocaine users said they had been high on the drug while at home caring for their family, and 10.0 percent had at least one occasion on which they failed to take care of their home or family because they were high on cocaine or feeling its after effects.
