Health consequences and increased mortality with cannabis in the general population are not widely reported and remain controversial particularly regarding cancer and cardiovascular effects (Aryana & Williams, 2007; Hashibe et al., 2005; Kapp, 2003). Swedish soldiers (N=45,540) who were high consumers of cannabis, which was defined as use on more than 50 occasions, were followed for 15 years. After controlling for social background variables in a multivariate model, no excess mortality was found (Andreasson & Allebeck, 1990). In 65,171 Kaiser Permanente acquired immune deficiency syndrome (AIDS) database medical care program enrollees aged 15 through 49 years, current cannabis use was not associated with a significantly increased risk of non-AIDS mortality in men and of total mortality in women (Sidney et al., 1997). Cannabis use was associated with a decreased risk of premature death (odds ratio=0.83, p=0.02) in 561 substance abusers in Sweden admitted to a detoxification unit from 1970 through 1978 and who were followed until 2006. Chronic alcohol users had increased risk of non-drug related death. This study had patients with schizophrenia, substance induced psychosis, affective disorders, neurosis, anxiety,
