Marijuana Addiction: Signs, Withdrawal, and Treatment Options in New Jersey

Many people believe cannabis is non-addictive and harmless. Unfortunately, this misconception is one of the reasons that many are unable to recognize cannabis use disorder (CUD). The fact is that marijuana addiction is a clinically recognized disorder that affects millions in the United States. Most affected will have their addiction gradually deteriorate their ability to function normally, their mental and physical health, and their relationships over time.

If you or a loved one has found that you can no longer control or stop your marijuana use, Meridian Recovery is here to help with evidence-based cannabis addiction treatment in New Jersey.

  • Marijuana is a widely used substance containing THC that can alter mood and perception, with higher-potency products increasing the risk of addiction.
  • Cannabis use disorder develops when repeated THC use changes the brain’s endocannabinoid system, leading to tolerance and dependence.
  • Signs of addiction include inability to quit, increased use, cravings, neglecting responsibilities, and continued use despite negative effects.
  • Withdrawal symptoms can begin within 24–72 hours and include irritability, anxiety, sleep issues, reduced appetite, and cravings lasting up to two weeks.
  • Treatment primarily relies on behavioral therapy and addressing co-occurring mental health conditions, as no FDA-approved medications exist for cannabis use disorder. 

What Is Marijuana?


Marijuana refers to the dried flowers, leaves, and extracts from the Cannabis sativa plant, which contains the active ingredient THC (tetrahydrocannabinol) as its main psychoactive compound.[2]

Marijuana is smoked, vaped, eaten in edibles, or used in concentrated forms. In New Jersey, recreational cannabis became legal in 2021, and is known for having many different effects on the person who has consumed it based on its method of administration, the amount consumed, and personal differences.[3] Effects can range from relaxation and altered perception of senses to anxiety and paranoia.[4]

The last two decades have seen cannabis products with significantly higher levels of THC in them. Current products available today, including certain vape pens and concentrates, are much more potent than products available ten years ago. There is a direct and fairly strong correlation between the potency of these products and the increasing prevalence of cannabis use disorder.[5]

 

Marijuana Addiction and Abuse

Marijuana use disorder occurs when the brain’s endocannabinoid system adapts to regular THC use. Repeated use causes the brain to reduce its natural endocannabinoid production and start becoming reliant on external THC to stay in balance, resulting in tolerance and uncomfortable withdrawal symptoms when marijuana use stops.[6]

Not all marijuana users will develop a cannabis use disorder, but the risks increase significantly for those who use marijuana frequently, use high-potency products, start at a younger age, or have a mental health condition. People who use marijuana daily or in large amounts and those using concentrated forms of cannabis such as wax, shatters, or vape cartridges have the greatest probability of developing a cannabis use disorder.[7]

 

Signs of Marijuana Use Disorder

Because cannabis use has become widely accepted socially and is legal in New Jersey, it can be difficult to determine when someone has crossed over from casual use to addiction. Some signs that a user has a marijuana addiction include:

  • Usage more than intended.
  • Unsuccessful attempts to quit or cut down.
  • Excessive time spent getting, using, and recovering from cannabis.
  • Continued use despite worsening mood, motivation, relationships, and performance at work or school
  • Giving up activities previously enjoyed in exchange for acquiring, using, and recovering from cannabis.
  • Relying on marijuana to relax, sleep, or control anxiety.
  • Experiencing withdrawal symptoms after stopping cannabis use.
  • Continued use despite a worsening of mental health symptoms, such as anxiety or paranoia

Marijuana Withdrawal and Detox


Cannabis withdrawal has been classified as a disorder in the DSM-5, meaning that there is significant recognition that cannabis withdrawal is both quite common and more uncomfortable than many people would think.[8] Withdrawal symptoms may begin as soon as 24 hours but usually within 72 hours after cessation of use, and may last between one and 2 weeks.[9] Some of the most commonly reported withdrawal symptoms for cannabis include:

  • Anger, irritability, and mood swings
  • Anxiety and restlessness
  • Sleep disturbances and vivid dreams
  • Reduced appetite and nausea
  • Headaches
  • Intense cravings

While cannabis withdrawal may not be medically dangerous, there may be times when the discomfort, especially sleep difficulties, irritability, and anxiety, creates a motive to relapse during the early days of recovery. Recovery and treatment programs can support clients through this withdrawal phase with a range of clinical supports, coping skills, and, when appropriate, referrals to inpatient medical treatment centers that can assist with detoxification.

Marijuana Addiction Treatment at Meridian Recovery

In order to successfully treat marijuana addiction, both the behavioral habits of the client and any underlying mental health issues must be addressed through an evidence-based, individualized program developed by staff who are trained to understand the complexity of the disorder. Meridian Recovery in New Jersey provides several treatment programs for cannabis use disorder within our partial hospitalization program (PHP), intensive outpatient program (IOP), and outpatient services.

There are no FDA-approved medications specifically for marijuana use disorder, making behavioral therapy the cornerstone of treatment.[10] 

Marijuana and Co-Occurring Disorder Treatment

Mental health disorders such as anxiety, depression, and psychosis are the most common co-occurring disorders in people seeking treatment for cannabis addiction.[11] A large number of people use cannabis to manage other mental health symptoms without realizing that heavy cannabis use often exacerbates those mental health symptoms over time. 

Meridian Recovery has a unique dual diagnosis program that provides integrated treatment to address both cannabis use disorder and the co-occurring mental health disorder that may be at the root of the issue. The underlying principle of the dual diagnosis approach is that to achieve sustained recovery, both cannabis use disorder and the co-occurring mental health disorder need to be addressed simultaneously.

How serious is marijuana addiction?

Cannabis use disorder is a clinically recognized and serious medical condition. While there may be no immediate medical risk associated with quitting like with opioids or alcohol, it still affects a person’s life, health, motivation, and relationships for the worse, mostly for long-term, chronic users. Studies suggest chronic heavy cannabis usage is related to the rise in anxiety, depression, and even psychosis in some people. For many, quitting without professional assistance is more challenging than they anticipated, due to the uncomfortable withdrawal symptoms and dependence.

What are the signs of marijuana use disorder?

According to the DSM-5 there are 11 different criteria to define a cannabis use disorder; these include but are not limited to, using more than intended, inability to stop using, continued usage after experiencing negative consequences, and experiencing cravings or withdrawal symptoms. To diagnose a person, they must meet at least 2 of these criteria within one year, while the level of severity is determined by the number of criteria met.[12] A formal assessment can be performed by a healthcare provider or a clinical evaluator.

What medication is used to treat marijuana addiction?

Currently, there are no FDA-approved medications to treat cannabis use disorder. Research has looked at using some medications to help treat the different withdrawal symptoms, such as using sleep aids to treat insomnia or anti-anxiety medication to treat anxiety; however, no medications have been formally approved for this usage. Because of this, the best supportive treatment for cannabis use disorder is behavioral therapy.

What mental illnesses are linked to marijuana use?

Chronic heavy cannabis usage is associated with a rise in anxiety disorders, depression, and, in some people who have a genetic predisposition, will show signs of psychosis or schizophrenia. Additionally, cannabis usage may result in the aggravation of pre-existing mental health disorders. Using cannabis at an early age and using heavy potency cannabis can make these associations stronger. People whose cannabis usage is accompanied by mental health symptoms need to receive integrated dual diagnosis treatment.

What percentage of marijuana users develop an addiction?

Studies have estimated that 22% to 30% of cannabis users develop an addiction. As cannabis products become more potent, this study is likely to misrepresent the current risk. Additionally, risk factors are greatly increased for people with a co-occurring mental health disorder or a family history of a substance use disorder.
