Among year-before-last initiates of marijuana, 42.4 percent had not used marijuana during the past year, 51.8 percent had used marijuana in the past year but were not dependent on marijuana, and 5.8 percent were both using and dependent on marijuana in the past year.

The National Survey on Drug Use and Health (NSDUH) is an annual survey sponsored by the Substance Abuse and Mental Health Services Administration (SAMHSA). The 2004 to 2006 data used in this report are based on information obtained from 203,870 persons aged 12 or older. The survey collects data by administering questionnaires to a representative sample of the population through face-to-face interviews at their place of residence. The NSDUH Report is prepared by the Office of Applied Studies (OAS), SAMHSA, and by RTI International in Research Triangle Park, North Carolina. (RTI International is a trade name of Research Triangle Institute.) Information on NSDUH used in compiling data for this report is available in the following publication: Office of Applied Studies. (2007). Results from the 2006 National Survey on Drug Use and Health: National findings (DHHS Publication No. SMA 07-4293, NSDUH Series H-32). Rockville, MD: Substance Abuse and Mental Health Services Administration. Information for earlier NSDUHs is available in the following publications: 2005 NSDUH: (DHHS Publication No. SMA 06-4194, NSDUH Series H-30) 2004 NSDUH: (DHHS Publication No. SMA 05-4062, NSDUH Series H-28) Also available online: http://oas.samhsa.gov. Because of improvements and modifications to the 2002 NSDUH, estimates from the 2002 through 2006 surveys should not be compared with estimates from the 2001 or earlier versions of the survey to examine changes over time. |
