Comedian Pete Davidson, 31, recalled being a daily user of marijuana and experiencing psychosis.
The soon-to-be first-time father has since stopped using the drug.
The potential for psychosis to become chronic is alarming to some experts, such as licensed mental health counselor and anxiety disorders specialist Eliana Bonaguro.
“Paranoia can appear during intoxication or shortly after, especially with high-THC strains, large doses, or in people with a genetic or mental health vulnerability,” Bonaguro told NTD.
The potency of cannabis matters, according to Bonaguro who added that THC levels above 20 percent overwhelm brain chemistry as well as destabilize thought and perception.
"High-potency cannabis can steal your reality and once someone begins experiencing psychosis, it takes less to trigger it," she said.
Davidson spoke further about the challenges he had with substance abuse in his 20s at a time when he was performing comedy on NBC's "Saturday Night Live" in 2014.
In addition to SNL, Davidson starred in "Riff Raff" along with Jennifer Coolidge and many other Hollywood movies.
“I was a big drug addict,” Davidson said. “I would go to rehab and stuff, and I do have mental stuff, and I was in therapy, but if you’re a drug addict none of that works. You can’t go to therapy on a bunch of drugs and expedite it to work.”
Because therapy or counseling with a licensed professional requires insight, Bonaguro tells her clients that engaging in drug use interferes with that cognitive ability.
"THC can disrupt short-term memory, attention, and executive functioning," she said. "It reduces creativity, motivation, ability to focus and undermines therapy, even if the person isn’t high in session. Sobriety isn’t just safer; it’s essential for recovery and for therapy to truly work."
Davidson’s girlfriend, Elsie Hewitt, 29, announced on social media last month that the couple is expecting their first child.
Hewitt is an actress and model known for playing Victoria in the feature film "The Pick Up Artist."
