Cannabis Is Legal in New Jersey. What That Means in Treatment.
New Jersey legalized recreational cannabis for adults 21 and older in 2021. Legality does not change the clinical reality: cannabis use disorder is a recognized DSM-5-TR diagnosis, withdrawal is real, and Still Detox New Jersey does not offer or endorse marijuana maintenance.

TRICARE In-NetworkCan you use cannabis during addiction treatment in New Jersey?
No. Still Detox New Jersey does not permit cannabis use during treatment and does not offer marijuana maintenance. Cannabis use is addressed clinically like any other substance, regardless of its legal status in the state. New Jersey law protects adults from arrest for possession but does not require treatment facilities to allow use on their premises.
The New Jersey Cannabis Regulatory, Enforcement Assistance and Marketplace Modernization Act (NJCREAMMA, N.J.S.A. 24:6I-31 et seq.) legalized adult-use cannabis in 2021. Adults 21 and older may possess up to six ounces. The statute does not override facility policies, clinical protocols or federal drug-free workplace requirements.
Cannabis use disorder appears in the DSM-5-TR under "Cannabis-Related Disorders". The National Institute on Drug Abuse (NIDA) estimates that approximately 9 percent of people who use cannabis develop dependence, rising to about 17 percent among those who start in adolescence.
What is cannabis use disorder and how common is it?
Cannabis use disorder is a DSM-5 diagnosis characterized by continued use despite clinically significant impairment or distress. Roughly 3 in 10 people who currently use cannabis meet the diagnostic criteria.
The DSM-5 lists 11 criteria for cannabis use disorder, including tolerance, withdrawal, unsuccessful efforts to cut down and continued use despite social or interpersonal problems. Meeting two or three criteria within a 12-month period indicates mild severity; four to five indicates moderate; six or more indicates severe.
National survey data from SAMHSA's 2021 National Survey on Drug Use and Health show that approximately 16.3 million people aged 12 and older had cannabis use disorder in the past year.
The disorder is not about willpower. Chronic THC exposure downregulates CB1 receptors in the brain, producing measurable tolerance. When use stops, the receptor system needs time to recalibrate, which is the biological basis of withdrawal symptoms.
What does cannabis withdrawal actually feel like?
Cannabis withdrawal produces irritability, insomnia, decreased appetite, anxiety and cravings that peak around days two through six after the last use. Symptoms are not life-threatening but are uncomfortable enough to drive relapse.
The DSM-5-TR recognizes cannabis withdrawal as a distinct diagnosis. Symptoms typically begin within 24 hours of cessation and include restlessness, depressed mood, physical discomfort such as abdominal pain or tremor, and vivid or disturbing dreams.
Peak severity occurs between days two and six. Most symptoms resolve within two weeks, though sleep disruption and cravings can persist for 30 days or longer in people with heavy, long-term use. At Still Detox New Jersey, the clinical team monitors withdrawal symptoms daily and adjusts comfort medications as needed.
People who use cannabis concentrates (wax, shatter, vape cartridges above 70 percent THC) report more intense withdrawal than those who use flower. The higher the baseline THC exposure, the more pronounced the receptor downregulation and the longer the adjustment period.
How does cannabis interact with psychiatric medications?
THC affects the same dopamine, serotonin and GABA pathways that psychiatric medications target. Using cannabis while taking antidepressants, mood stabilisers or anti-anxiety medications can reduce efficacy and increase side effects.
THC is a partial agonist at CB1 receptors, which modulate dopamine release in the mesolimbic pathway. This is the same system that SSRIs, SNRIs and atypical antipsychotics are designed to regulate. Concurrent cannabis use introduces an uncontrolled variable that makes dosing unreliable.
CBD, the other major cannabinoid, inhibits the CYP3A4 and CYP2C19 liver enzymes that metabolize many psychiatric drugs. A person using CBD products while taking lamotrigine or clobazam may experience elevated blood levels of those medications without any dose change, increasing the risk of toxicity.
At Still Detox New Jersey, the psychiatrist evaluates every resident for co-occurring mental health conditions. Stabilising psychiatric medication is only possible when the clinician knows exactly what substances are and are not in the person's system. This is one reason cannabis use is not permitted during treatment.
What does New Jersey law actually say about cannabis and treatment facilities?
NJCREAMMA protects adults from criminal penalties for possession of up to six ounces but does not require any healthcare facility to permit cannabis use on site. Treatment providers retain full authority over their clinical environment.
N.J.S.A. 24:6I-31 et seq. created the Cannabis Regulatory Commission (CRC) to license cultivators, manufacturers, distributors and retailers. The statute explicitly states that nothing in the act requires an employer, property owner or healthcare provider to accommodate cannabis use.
Federal law compounds this. The Drug-Free Workplace Act of 1988 requires organizations receiving federal funds to maintain drug-free premises. Still Detox New Jersey, as a Joint Commission-accredited facility that accepts TRICARE, maintains compliance with both state and federal standards.
Why does Still Detox New Jersey not offer marijuana maintenance?
Marijuana maintenance has no evidence base equivalent to FDA-approved medications for other substance use disorders. No randomized controlled trial supports substituting cannabis for structured treatment of alcohol, opioid or stimulant dependence.
The concept of marijuana maintenance suggests that cannabis can replace a person's primary substance of dependence and reduce harm. While anecdotal reports exist, no peer-reviewed clinical trial has demonstrated that this approach produces sustained recovery outcomes. The American Society of Addiction Medicine (ASAM) does not recognize marijuana maintenance as an evidence-based treatment modality.
Still Detox New Jersey uses FDA-approved medications where indicated and delivers evidence-based behavioral therapies including cognitive-behavioral therapy, dialectical behavior therapy and motivational interviewing. The treatment team addresses cannabis use the same way it addresses any other substance: through medical assessment, individualized planning and structured clinical care.
Families and individuals sometimes arrive at Still Detox believing that cannabis is harmless because it is legal. The clinical team provides psychoeducation about the distinction between legality and clinical safety, helping residents make informed decisions about their recovery.
