Daniel Juarez, an 18-year-old from Brighton, died September 26, 2012 after stabbing himself 20 times. In an autopsy report that had never been made public before, but was obtained by CBS4, his THC level – the active ingredient in marijuana- was measured at 38.2 namograms. In Colorado, anything over 5 nanograms is considered impaired for driving.

Juarez was nearly eight times the legal limit.

Police and witnesses then say Juarez literally ran wild, stripping off most of his clothing and running into his nearby apartment. There, he got a knife and stabbed himself 20 times, one of the stab wound piercing his heart. Juarez’s autopsy report lists his manner of death as suicide with ‘marijuana intoxication’ as a ‘significant condition.’

Those using “super strength” marijuana every day are three times more likely to have a psychotic episode than others who had never tried “super strength” marijuana. The THC can be four-times stronger than what older generations smoked.

Psychosis is defined as a form of mental illness where people experience delusions, hallucinations, or both at the same time. Associated with conditions such as schizophrenia and bipolar, some victims are so badly affected that they end up committing suicide or seriously harming others because they believe they are being ordered to do so by voices in their heads.

As many as a quarter of new cases of psychotic mental illness can be blamed on super-strength strains of cannabis, scientists will warn …

The research found that marijuana use “tended to precede or coincide with episodes of mania.”

The study, published in the Journal of Affective Disorders, raises particular concerns about adolescents and the problems cannabis use can have on their development.

A pro marijuana group in Ohio is attempting to place a constitutional amendment on the ballot to legalize marijuana for recreational use. If the amendment gets placed on the ballot and should it pass, employers fear that with more people using marijuana the pool of drug-free employees will decline and safety in the workplace will be compromised.

"I’m absolutely opposed to [legalizing marijuana]," said Don Crane, president of Western Reserve Building Trades, which represents more than 6,000 workers in the skilled trades. Many trade jobs have dangerous components.
