I’m sharing my direct experience of my 19-year-old son, Johnny Stack, who used high-potency marijuana, which triggered psychosis, which led to his suicide. Johnny was 14 years old when legal recreational marijuana came to Colorado. His friend’s brother had a medical marijuana card, and he gave Johnny his first marijuana at a high school party. (Yes, we live in Colorado. Yes, it is everywhere. Yes, your kids can get it too unless you chain them to their beds.) He later started “dabbing” high-THC marijuana (they smoke a very potent wax or shatter form), which triggered bizarre episodes of psychosis, a first suicide attempt, and delusional thinking (the FBI was after him, the world “knew about him,” the mob had it in for him, we were “in on it,” etc.).
We would dis-enroll him from his current university, admit him to mental hospitals, and they would stabilize him with medications, and he’d recover…until he used marijuana again. Eventually, even when he stopped using marijuana, the psychosis did not go away, and he developed schizophrenia.
He was put on anti-psychotics to control the delusion, but he didn’t like how “stupid” they made him feel, because he was extremely intelligent. So, he stopped taking them without telling us (a common problem with the disorder). When he died, he had given up marijuana and wasn’t depressed. But because he wouldn’t take the medications he now needed, the paranoid delusions told him to stop the pain, and he jumped.
Johnny said 3 days before he died, “I want you to know you were right all along. You said that marijuana would hurt my brain, and it’s ruined my mind and my life.” If we didn’t live in Colorado, and he wouldn’t have been able to so easily access marijuana, I know my son would still be with us today.

Rest in peace my beloved son

Dear Laura,
Thank you for sharing Johnny with us. May he live forever in our hearts and in those who heed his warning that you are right about the drugs.
Wishing you peace as you share Johnny with others to spare more families our pain of losing our children. There are too many families losing too many children.
Thank you, Sally. It would be such a blessing if any more young people are spared.
My heart aches for you…the lies are being told continually about how “safe” & “harmless” THC is all in service to those profiting from the sales & usage. Thank you for bravely telling the truth. May God grant you peace.

State of Washington set to change regulations recognizing harm of high potency, including psychotic break. Here is the file. They should never have allowed any of these products out on the market. Thank you for sharing your very personal story – it is so very important for others to read.

Pamela, wow!! Thank you for posting this very important link! Hooray for some very smart legislators for once. I will share it!
Your family is in our thoughts. You have a large network here. We continue to educate on the harms of high potency pot (>10% by definition, which does not exist here in Colorado). Happy to chat if interested. KF
Thank you Ken. I always told him, “Don’t do drugs or pot, because it will kill your brain cells.” “Don’t smoke weed, because it will make you stupid and cause mental health issues,” etc. etc. Kids today think we don’t know what we’re talking about. Hey, it’s Colorado, it’s legal, it must be safe, right?! Ugh, so awful. I miss my boy. Two months today.
Thank you for sharing your son’s story, Laura.
How and why has it been decided that anything 10%< is deemed "high potency?" Seems arbitrary without proper source/context.
In response to Uluk – I think you mean <10% THC is considered low strength THC. When only two categorical levels of potency are being evaluated in a study ("low" and "high"), leading psychiatric epidemiologists in Europe have chosen 10% as the cutoff point (e.g. DiForti et al., 2019, The contribution of cannabis use to variation in the incidence of psychotic disorder across Europe (EU-GEI):a multicentre case-control study). You must understand that potency is generally lower in Europe, and they chose 10% because that value distinguished a more potent product known on the street as "skunk" from the type of product more common in the last century. Because so little epidemiology is conducted in the U.S. on the impacts of different strengths of THC, there are no generally accepted "low" and "high" levels here.

Hi Laura – I’m so saddened by your tragic loss.
My story is here also.
I was lucky in that I was able to resist the urge to kill myself, however even nearly 50 years later, I’m still in therapy.
I’ve put your son’s story on my “Marijuana Links Page,” under the first heading – https://georgespicka.weebly.com/marijuana-links.html
Thank you for including Johnny’s story!
This is so sad. Thank you for your courage to tell your story
Laura,
An article in the USA Today led me to this website. I am so sorry this happened to your beautiful son. We are now dealing with exactly the same issue with my beautiful 19 year old son. As we speak, instead of going to his university classes here in Florida, he is in a psychiatric facility for the 4th time and is now suffering from schizophrenia after smoking marijuana nonstop for several weeks. We are desperate to get him help and will do anything within our power to help him but are finding it so difficult to find the appropriate treatment and care not only because so few facilities are able to help him, but mostly because he has no recognition of what is happening to him and since he is 19 and technically an adult it is almost impossible to get him to agree to anything. Additionally we have tried legally to gain control over him to force him into treatment but since it is “only marijuana” outpatient treatment is the only option and there are limited legal enforcement tools. Please if anyone out there has any advise please please help. Laura my heart aches for you and your family.
Perhaps reach out to a community anti-drug coalition (They may know a treatment center for these issues.) Check out the website, Parents Opposed to Pot, or the private Facebook group of same name (Ask to join). Best of luck to you; sounds very tough.
I’m so sorry to hear what you’re going through with your beautiful son. It sounds exactly like what happened to my Johnny. If he is in a center, they will keep him safe, but it’s afterward that’s worrisome. My son had taken me off all the medical approvals as well, so he shut me out of being able to help him. Of course, hindsight is 20/20 but looking back, I would have called the Colorado Crisis Centers and gotten social services involved to get our family help—throwing all pride and concern to the wind. I would have called the police to pick him up. I would have mortgaged our home and done anything I could to get him into private inpatient. I would have moved out of Colorado, where pot is seen like no big deal, and there are drugs everywhere. There are centers that handle dual diagnosis with mental health and drug addiction issues. The trick is to get the state to legally recognize that he is incompetent and unable to make decisions for himself and get legal custody. You can get his psychiatrist to force the hospital to give him a shot that will stick for 3 months vs. trying to get him to take something every day he won’t take because he doesn’t think anything is wrong with him. I’m so sorry you’re dealing with this. Prayers for you all!
Linda- I am in the exact same boat. My son is 20 and is in a psychiatric hospital in Laguna California. He was dabbing all through high school and just started shrooms the last three months. He is now manic with psychotic episodes or schizophrenic. They are hoping to get him regulated on some medication and then move him into a treatment center. This has been a nightmare.
I am so sorry for your loss. I will keep your family in my prayers.
I agree with a lot of this article. I do not think marijuana needs to be legalized in over 10 to 20 states. Legalizing it everywhere will also make the Mexican Cartels even deadlier.
Only 1 in 10 people get addicted to pot, but if everyone starts doing it….then we have a huge issue on our hands.
Another strain of pot to watch out for is the K2 strain of pot. I used it heavily when I was 19 and in college and it almost took my life. I think/ hope that it is outlawed everywhere by now but it should have taken my life as I was also a high stakes poker online poker player at a very young age which is also very dangerous.
We are terribly sorry for your great loss. Reading your story is strikingly similar to our own. Our son, David, killed himself Dec 5, 2018 at age 19. He also was psychotic from years of using high THC marijuana. Like Johnny’s, his autopsy was negative for any substance.
David started smoking about age 14 we think. He was deceived into believing that weed helped his social anxiety and depression. In reality, it caused it. He was neither depressed nor anxious before pot.
Like your son, David was greatly loved. We saw him self destructing and didn’t know how to stop it. By the time he wanted help, it was too late.
