New Study Finds Genetic Links Between Marijuana and Psychosis

Research continues to link marijuana use with psychosis.

Nationwide, many states have legalized marijuana to varying degrees, and the Trump Administration has moved to ease federal restrictions on the drug. But while policymakers push for more marijuana, scientific evidence continues to show that’s a bad idea.

Researchers at King’s College London recently published a study identifying the genetic pathways that connect marijuana use to psychosis.

The researchers identified 553 genetic markers associated with psychosis, and their analysis showed that far more biological pathways overlap between cannabis use disorder and psychosis than would be expected by chance.

Importantly, the study found marijuana use may be driving psychosis — not simply appealing to people who are already prone to psychosis.

We have written before how high-potency marijuana is linked to psychotic disorders. Modern marijuana can contain 15% to 30% THC — sometimes even 60% THC — compared to just 3% THC in marijuana from the 1960s. The higher the potency, the greater the risk there is to users.

We have also reported that cannabis use among people with a history of psychosis “sharply increased” in states where recreational marijuana was legalized. Teen psychiatric emergencies spiked in Massachusetts after marijuana commercialization began there as well.

In Arkansas, “medical” marijuana use has skyrocketed in recent years, and post-traumatic stress disorder is now the most common reason cited for “medical” marijuana use. But if marijuana is actually hurting people’s mental health, then it’s deeply concerning that so many Arkansans have been approved to use it for PTSD.

All of this simply underscores what we have said for years: Marijuana may be many things, but “harmless” simply is not one of them.

Guest Column: Dying with Dignity vs. “Death with Dignity”

In a recent episode of “60 Minutes,” interviewer Scott Pelley said to his guest, “You don’t have much time. Why are you spending time doing this?” His guest, former U.S. Senator Ben Sasse, who received a fatal diagnosis of pancreatic cancer in December, replied with a laugh, “You invited me, so I assume you needed to fill some time.”  

Short of a miracle, Sasse won’t see his 14-year-old son grow up. He won’t walk his daughters down the aisle. And yet, he is teaching the nation a stunning lesson on dying with dignity. Sasse warns against the allure and the limits of political power and proclaims what matters more. Committed to free markets, he warns against the illusion that “more consumption can make you happier.” He’s at the same time optimistic about what technologies can provide and concerned about what has happened to our sense of self and happiness, especially young people. 

Sasse is not being stoic, as though death is not a big deal. He mourns what the loss means to his family and regrets what he missed traveling for work instead of being at home. He regrets the pain that cancer has brought to him. But how he is dying is making a rare statement to the world, and it is being heard. As Dr. James Wood described in a recent World article: 

In a culture that kills to avoid hardship and hides death to avoid reckoning, a man dying well on high-profile platforms is a subtly radical act. He is, without quite saying so, making an argument for life—for its dignity, its giftedness, its meaning even at the last. 

His voice is especially powerful in a world that continues to accept various forms of euthanasia and doctor-assisted death. Across Europe, Canada, and a number of American states, advocates of what is often called “medical assistance in dying” or MAiD, market the promise of “death with dignity.” Unspoken in that terminology is the assumption that we need “death with dignity” because there is no such thing as “dying with dignity.” There is no value to be found in facing suffering or enduring pain to honor life until its God-given end. So many speak as if giving up on life takes courage and compassion.  

Within the godless and hopeless framework of a naturalistic worldview, life is, as Shakespeare put into the mouth of Macbeth, “a tale told by an idiot full of sound and fury, signifying nothing.” Why suffer to preserve such a meaningless existence when no higher purpose or value is available to be found? To die is to escape from such a life. Once pleasure or plenty is no longer available to us, there is no dignity to be found in how we die. 

The Christian view is centered on Christ’s death, which restored the dignity with which God created us. Because death is transformed, as Dietrich Bonhoeffer wrote, there is dying with dignity. There is meaning and significance in the courage to face life’s end and the pain that so often accompanies it. In the Christian worldview, death in all its pain and suffering, is redeemable in the life of Christ, who defeated death. 

That sort of courage is undeniable when witnessed in real life. As President Clinton, after being soundly critiqued by Mother Theresa on the issue of abortion, put it, “It’s difficult to argue with a life so well lived.” In the same way, what we are hearing and witnessing in these final days of Ben Sasse, is that it is difficult to argue with one dying so well.  

Indeed, as a wise pastor once observed, our children will remember all sorts of things about us, but the way in which we die is what they will most remember about our faith. “Death with dignity” is a farce, a damnable idea that dehumanizes us individually and collectively. But dying with dignity, even as we pray for grace and peace for him and his family, is a profound gift that God is giving all of us right now through Ben Sasse.
