I didn’t think I could get addicted to weed. I was wrong – and I’m not alone

Public perceptions of cannabis often overlook the potential for dependency, leading many users to believe the substance is non-addictive until they experience the clinical symptoms of Cannabis Use Disorder (CUD). This gap in understanding can delay treatment for individuals struggling with severe cravings and behavioral compulsions.

Reporting from The Guardian on May 8, 2026, illustrated the extremity of this struggle through the experience of an 18-year-old named Amy. Amy found herself searching through a dumpster to recover a THC vape cartridge she had previously discarded in a desperate attempt to stop using the substance.

The behavior described—rooting through garbage bags and stinking detritus to retrieve a drug—highlights a level of compulsion that transcends recreational use. Amy had repeatedly attempted to throw the cartridge away to prevent herself from returning to it, yet the drive to consume the THC overrode her intentions.

This pattern of behavior is characteristic of addiction, where the pursuit of the substance becomes a primary motivator, often leading to actions that the individual finds distressing or socially unacceptable.

Medical professionals recognize this condition as Cannabis Use Disorder. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), CUD is defined as a problematic pattern of cannabis use leading to clinically significant impairment or distress.

Diagnosis typically involves assessing whether a person meets several criteria, such as using more of the substance than intended, experiencing unsuccessful efforts to cut down, or spending a significant amount of time obtaining the drug.

The rise of high-potency cannabis products, particularly THC vape cartridges, has complicated the public health landscape. These carts provide concentrated doses of tetrahydrocannabinol (THC), the primary psychoactive component of cannabis, which can lead to a more rapid development of tolerance and dependency compared to traditional flower.

Higher concentrations of THC can more aggressively alter the brain’s reward system, specifically the dopamine pathways. Over time, the brain may downregulate its own cannabinoid receptors, meaning the user requires more of the substance to achieve the same effect or simply to feel normal.

The risk of developing CUD is significantly higher for those who begin using cannabis during adolescence. At 18, Amy was at a developmental stage where the prefrontal cortex—the area of the brain responsible for executive function, impulse control, and decision-making—is still maturing.

Research indicates that early onset of cannabis use can interfere with this brain development, potentially increasing the likelihood of long-term dependency and cognitive impairments.

Dependency is often confirmed when a user attempts to quit and experiences cannabis withdrawal syndrome. While less severe than withdrawal from opioids or alcohol, it is a documented medical reality.

Common withdrawal symptoms include:

• Irritability, anger, or aggression
• Sleep difficulties, including insomnia and abnormal dreams
• Decreased appetite or weight loss
• Physical symptoms such as chills, sweating, or abdominal pain
• Anxiety and restlessness

For many, these symptoms create a cycle of relapse. The discomfort of withdrawal drives the user back to the substance, reinforcing the addictive loop and making it difficult to maintain abstinence without professional support.

Treatment for CUD often involves a combination of behavioral therapies. Cognitive Behavioral Therapy (CBT) is frequently used to help patients identify the triggers that lead to use and develop healthier coping mechanisms to manage cravings.

Motivational Enhancement Therapy (MET) is another common approach, designed to resolve ambivalence about quitting and increase the patient’s internal motivation to change their behavior.

Public health experts emphasize that the misconception regarding cannabis’s lack of addictiveness remains a barrier to care. When society labels a substance as safe or non-addictive, individuals struggling with dependency may feel shame or confusion, believing they are uniquely weak rather than suffering from a recognized medical disorder.

Addressing this gap requires a shift in how cannabis is discussed in wellness and public health contexts, moving toward a more nuanced understanding of potency, age of onset, and the clinical reality of addiction.
