Anthropological discoveries in Asia have proved that people have been using cannabis for nearly 12,000 years, and it’s not going anywhere anytime soon. In the U.S., over 64 million people reported using cannabis in 2024, according to a national survey, making it the most widely used illicit substance in the country. The survey also showed that more young people have started using it, and with South Carolina’s push in 2025 to legalize medical marijuana (in hopes of replacing dependence on opioid pain medications), those numbers may just increase.
Of course, marijuana may help some people more than it harms them, but everyone who uses it is at risk for developing cannabis use disorder (CUD) to some degree, especially if they start using it at an early age.
Waypoint Recovery Center treats and educates our community on CUD in North Charleston and Cameron, SC., but for our readers who need information now, this article can help you understand the pitfalls of marijuana use, especially when it leads to paranoia.
Cannabis-Induced Paranoia: What You Need To Know
One of the many myths about marijuana usage would have you believe that marijuana is harmless and helps you enter a state of deep relaxation. While that may be true for some people, others can experience deep anxiety and even paranoia. Experts described paranoia as the incorrect belief that others consciously want to harm you, causing distress, relationship tension, and social withdrawal or isolation.
Healthline describes how smoking or ingesting cannabis can trigger paranoia:
- The main psychoactive element in marijuana, THC, binds to the region of your brain that regulates fear.
- Those elements overstimulate that brain region, nudging you to feel anxiety, paranoia, fear, or the restlessness associated with the body’s fight-or-flight response.
- Consuming large quantities of potent cannabis can temporarily but fully immerse you in heightened feelings of fear, anxiety, or unfounded suspicion of the people around you.
For many cannabis users, that’s how it goes: You smoke a little too much, and suddenly you’re trying to talk yourself out of the monster under your bed or the idea that everyone in the room is staring at you. It can be comical for some people, but if you’re more prone to cannabis-induced paranoia than others (this can be the case for anyone who’s more THC-sensitive), you can have adverse, paranoid reactions to cannabis that you don’t ever want to experience again.
Cannabis and Psychosis: The Real Threat
A few hours of feeling paranoid can be unpleasant, but that type of reaction isn’t the scariest thing that can happen when you consume cannabis. The real danger may lie in your increased risk of suffering from psychosis, which can be marked by paranoia:
- Paranoid delusions: When you’re having a psychotic episode, you might see or hear things that aren’t there.
- Constant suspicions: Psychosis might cause you to suspect everyone and everything around you of foul play, malice, or harm.
- Extreme fears: You could suffer from intense phobias or bizarre fears when you’re in the depths of psychosis.
If you or a loved one suspects they’re suffering from psychosis, it’s best to contact a doctor or mental health professional immediately, whether or not marijuana may play a factor.
The Harms of Marijuana
Beyond paranoia and psychosis, there are other reasons for people in recovery—and people who don’t struggle with substance use disorder—to avoid cannabis:
- Severe, ongoing vomiting: Using cannabis long-term can create cannabinoid hyperemesis syndrome (CHS), a condition that can send you to the ER, and often won’t go away unless you stop smoking marijuana.
- Developmental dangers: Young people and growing fetuses can both suffer from brain and developmental damage when exposed to marijuana.
- Complications for older adults: From increased risks of certain cancers and heart disease to dementia, dizziness, and memory problems, cannabis consumption can cause issues for older people.
- Relapse risks: While it isn’t proven, engaging in mind-altering substances like cannabis could compromise your ability to power through cravings and sustain your recovery.
- Cannabis use disorder: Luckily, people who have CUD usually only have a mild form of it, but it can still become severe and create the need for you to enter residential treatment.
