HC Deb 15 November 2000 vol 356 cc669-70W
Dr. Tonge

To ask the Secretary of State for Health how many cannabis psychosis cases there were in each of the last 10 years. [138451]

Ms Stuart

The table shows data from the hospital episodes statistics system (HES) and relates to in-patients with a primary diagnosis of psychotic disorder due to cannabinoids who have finished their hospital episodes under the care of a consultant. There are no comparable data prior to 1995–96.

We know that cannabis can have a range of adverse health effects in addition to those risks associated with smoking tobacco. The Department is currently funding research into patterns of use and the health effects of long-term heavy use of cannabis.

Estimated finished consultant episodes with a primary diagnosis of psychotic disorder due to cannabinoids, England, 1995–96 to 1998–99
Number
1995–96 360
1996–97 280
1997–98 310
1998–99 300

Notes:

  1. 1. Figures have been rounded to the nearest ten.
  2. 2. Figures for 1998–99 are provisional as no adjustments have been made for shortfalls in data.
