MARY JANE: She's a dangerous friend
Realizing that many think marijuana should be legalized and taxes made, I wanted to put this article out here. Marijuana is not a harmless drug as many have touted. Think about this article and realize that the marijuana of the Woodstock days is long gone and the effects are getting more costly with each "toke over the line." Just something to chew on with your morning scones and herbal teas.
SATURDAY, Feb. 27 (HealthDay News) -- Long-term use of marijuana can lead to increased risk of developing hallucinations, delusions and psychosis, a new study shows.
Australian researchers asked nearly 3,100 young adults averaging about 20 years of age about marijuana use. They found that almost 18 percent reported using the drug for three or fewer years, about 16 percent for four to five years, and just over 14 percent for six or more years.
Among the participants, 65 had been diagnosed with a "non-affective psychosis" such as schizophrenia, and 233 had at least one positive item for hallucination on a diagnostic interview conducted for the study.
The researchers found there was an association between length of marijuana use and mental health.
"Compared with those who had never used cannabis, young adults who had six or more years since first use of cannabis [i.e., who commenced use when around 15 years or younger] were twice as likely to develop a non-affective psychosis and were four times as likely to have high scores on the Peters et al Delusions Inventory [a measure of delusion]," wrote Dr. John McGrath, of the Queensland Centre for Mental Health Research, Park Centre for Mental Health in Wacol, and colleagues. "There was a 'dose-response' relationship between the variables of interest: the longer the duration since the first cannabis use, the higher the risk of psychosis-related outcomes."
