Of the respondents surveyed, 13.3% reported they used cannabis occasionally and 38.7% reported they used cannabis regularly. Furthermore, survey results indicated that 12.7% of respondents reported some of the consequences from cannabis use experienced within the past year included public misconduct, such as fighting, arguing, and vandalism. In addition, 13.9% reported having experienced serious personal problems due to cannabis use at least once during the past year including injuries, suicidal thoughts, and sexual assault. Reported attitudes and perceptions of cannabis use include 13.3% perceived great risk associated with cannabis use.
