More Evidence Links Marijuana With Psychosis

New evidence underscores what we have said for years: Marijuana use carries a number of dangers, including a link to psychosis.

NPR reports this week,

Several past studies have found that more frequent use of pot is associated with a higher risk of psychosis — that is, when someone loses touch with reality. Now a new study published Tuesday in the The Lancet Psychiatry shows that consuming pot on a daily basis and especially using high-potency cannabis increases the odds of having a psychotic episode later.

“This is more evidence that the link between cannabis and psychosis matters,” says Krista M. Lisdahl, a clinical neuropsychologist at the University of Wisconsin, Milwaukee, who wasn’t involved in the study.

The article goes on to say the study found daily marijuana users were three times more likely to suffer a psychotic episode than non-users, and those who started using marijuana at 15 years of age or younger faced an increased mental health risk compared to those who started using marijuana when they were older.

Many of the study’s findings focus on use of “high potency” cannabis, but as the article notes, the average marijuana on the market in the U.S. and Europe qualifies as “high potency” cannabis — meaning the study has serious implications for everyone using so-called “medical” and recreational marijuana.

As we keep saying, marijuana may be many things, but “harmless” simply is not one of them.

Proposal Would Make It Easier to Use Marijuana in Arkansas

Yesterday we shared a commentary from our friends at the Colson Center for Christian Worldview highlighting a New York Times op-ed about the growing public health threat posed by marijuana.

This week a bill was filed at the Arkansas Legislature making it easier for Arkansans to use marijuana under the state’s so-called “medical marijuana” amendment.

Currently, Amendment 98 to the Arkansas Constitution lets Arkansans use marijuana if they have any one of a long list of qualifying conditions.

H.B. 1150 by Rep. Doug House (R – North Little Rock) expands the list of qualifying conditions to add the following:

  • adiposis dolorosa or Dercum’s Disease
  • anorexia
  • Arnold-Chiari malformation,
  • asthma,
  • attention deficit disorder,
  • attention deficit hyperactivity disorder
  • autism
  • bipolar disorder
  • bulimia
  • causalgia
  • chronic inflammatory demyelinating polyneuropathy
  • chronic insomnia
  • chronic obstructive pulmonary disease
  • complex regional pain syndrome Type I and Type II
  • dystonia
  • emphysema
  • fibrous dysplasia
  • general anxiety disorder
  • hydrocephalus
  • hydromyelia
  • interstitial cystitis
  • lupus
  • migraine
  • myasthenia gravis
  • myoclonus
  • nail-patella syndrome
  • neurofibromatosis
  • Parkinson’s Disease
  • posterior lateral sclerosis
  • post concussion syndrome
  • reflex sympathetic dystrophy
  • residual limb and phantom pain
  • restless leg syndrome,
  • Sjogren’s syndrome,
  • spinocerebellar ataxia
  • spinal cord injury or disease including without limitation arachnoiditis
  • syringomyelia
  • Tarlov cysts
  • traumatic brain injury

If passed, H.B. 1150 would let people with COPD or emphysema smoke marijuana.

It would let parents give marijuana to their child if the child tests positive for ADD or ADHD.

It would let people with traumatic brain injuries use marijuana.

Of course, research does not show that marijuana is effective treating these conditions. However, research has shown that marijuana smoke contains more tar and carcinogens than tobacco, and marijuana-use is linked to a host of mental problems, including permanent loss in IQ and increased risk of schizophrenia.

In other words, it probably isn’t a good idea to let people with lung disease smoke marijuana, and it probably isn’t a good idea to give marijuana to people with learning disabilities or brain injuries.

Arkansas’ marijuana amendment already makes it very easy for people to use marijuana, but H.B. 1150 arguably makes it even easier.
