Cannabis Use Disorder: Risks and Treatment

Cannabis is legal for adults in California and widely regarded as harmless, which makes cannabis use disorder awkward to discuss. It is nonetheless a real diagnosis affecting a meaningful minority of users, and the products available today bear little resemblance to what was consumed a generation ago.

Potency changed the picture

The THC content of cannabis flower has risen substantially over recent decades, and concentrates such as wax, shatter and vape oils can reach far higher concentrations still. Someone dabbing concentrate is consuming a different exposure from someone smoking a joint in 1990, and a great deal of the reassuring research on cannabis was conducted on the latter.

Higher potency is associated with higher rates of dependence, more severe withdrawal, more cannabis induced psychosis and more emergency presentations, particularly among people who started young. The plant did not become dangerous; the dose changed.

When use becomes a disorder

The same criteria apply as for any substance: loss of control, continued use despite harm, tolerance, withdrawal, and use crowding out other parts of life. In practice, the signs people notice:

  • Using more, or more often, than intended, and repeatedly failing to cut down
  • Needing to be high to relax, sleep, eat or socialize
  • Motivation and follow through eroding in ways that are easy to attribute to something else
  • Memory and concentration problems affecting work or study
  • Continuing despite it worsening anxiety, which it does for many people over time
  • Irritability, insomnia and appetite loss when stopping
  • Spending significantly more on higher potency products over time

Withdrawal is real

Cannabis withdrawal was disputed for years and is now well established. It is not dangerous, and it is unpleasant enough to keep people using. Symptoms typically begin within a day or two, peak over the first week and largely settle within two to three weeks, though sleep can take longer.

Expect irritability, anger and difficulty regulating temper, anxiety, insomnia with unusually vivid and unpleasant dreams, appetite loss and weight loss, restlessness, low mood, and physical symptoms including headaches, sweating and abdominal discomfort. The vivid dreams catch people off guard: cannabis suppresses REM sleep, and stopping produces a rebound.

Cannabinoid hyperemesis syndrome

A pattern that appears with long term heavy use: cycles of severe nausea and repeated vomiting, often with abdominal pain, in someone who finds that hot showers or baths relieve it. That detail is unusual and diagnostically useful.

It is frequently missed, because both patient and clinician associate cannabis with relieving nausea rather than causing it. People undergo repeated emergency visits and extensive investigation before anyone asks the right question. The definitive treatment is stopping cannabis, after which it resolves, and it returns when use resumes.

Mental health

The relationship with psychosis is well documented and often overstated in both directions. High potency cannabis use, particularly beginning in adolescence, is associated with increased risk of psychotic disorders, and the risk appears higher in people with family history. Most people who use cannabis do not develop psychosis, and the association is strong enough to take seriously in anyone with personal or family risk.

For anxiety the picture is more immediate. Many people use cannabis for anxiety and find over time that baseline anxiety worsens between uses, producing a cycle where the treatment sustains the problem. Where cannabis is being used to manage anxiety, depression, PTSD or insomnia, our dual diagnosis program treats the underlying condition, because removing the cannabis without addressing what it was doing rarely holds.

Treatment

No medication is approved for cannabis use disorder. Cognitive behavioral therapy, motivational enhancement and contingency management all have supporting evidence, and combinations work better than any single approach. Most people do well in intensive outpatient or outpatient care, since medical detox is not required.

Two practical points. Sleep needs specific attention, because insomnia is the most common reason people resume. And where cannabis has been the main way someone manages stress or social discomfort for years, the plan needs to include what replaces that function, rather than assuming the gap will close on its own.

Frequently asked questions

Can you actually be addicted to marijuana?

Cannabis use disorder is an established diagnosis and affects a meaningful minority of users, with higher rates among those who begin in adolescence or use high potency products. It is generally less severe than dependence on alcohol or opioids, and dismissing it entirely does a disservice to people struggling with it.

Is medical cannabis different?

The pharmacology is the same. A medical recommendation does not change how the drug interacts with the brain, and dependence can develop with medical use just as with recreational use. That does not mean medical use is illegitimate, only that it is not automatically exempt.

How long until I feel normal after stopping?

The worst of withdrawal covers one to two weeks. Sleep often takes three to four weeks to settle, and mood and motivation typically improve over one to two months. People frequently report that mental clarity keeps improving well past the point they expected.

Does CBD help with quitting?

Some early research is promising, and the evidence is not yet strong enough to recommend it as a treatment. Unregulated CBD products also vary considerably in what they actually contain, including THC content that is not always accurately labelled.
