There is little dispute that cannabis intoxication can lead to acute transient psychotic episodes in some individuals (D’Souza et al, 2004) and that it can produce short-term exacerbation or recurrences of pre-existing psychotic symptoms (Thornicroft, 1990; Mathers & Ghodse, 1992; Hall & Degenhardt, 2004). However, controversy remains about whether cannabis use can actually cause schizophrenia or other functional psychotic illness in the long term (Johns, 2001).
