Since the dawning of synthetic marijuana, there have been reports of side effects. The latest horror story to surface involving man-made weed comes from a group of Spanish researchers, who in their latest paper, imply the drug has now contributed to a frightening case of catatonic psychosis.

Researchers from the CEU Cardenal Herrera University and the Provincial Hospital of Castellón published a study earlier this week in the journal Psychiatry, which details the mind-numbing journey of a teenaged patient who they say experienced several months of psychotic episodes, similar to those brought on by Parkinson’s disease, as the result of habitual synthetic marijuana use.

Lead study author and physician Dr. Gonzolo Haro said although synthetic marijuana has been linked to various forms of psychosis, this is the first case where a patient with a past of synthetic marijuana abuse has experienced a virtual disconnection: “lost harmony of movement, akinetic walking and a rigid position of neck, head and arms similar to the praying mantis position.”

Dr. Haro says this specific case is a perfect example of dual pathology, which attempts to establish a connection between substance abuse and mental illness. He claims that more than 40 percent of patients with a predisposition toward alcohol abuse display behavior associated with metal disorders.

It is important to point out, however, that this study is in no way a reflection of the adverse effects of natural marijuana. In fact, while synthetic cannabinoids have reportedly caused mood swings and bouts of psychotic behavior in some adolescents, a recent study from the University of Calgary in Canada suggests that alcohol consumption is more likely to bring on psychosis than our good friend marijuana.
