    Medical Marijuana (Cannabis)

    You’ve likely heard that medical marijuana (cannabis) is being used more and more frequently to treat mental and physical health problems. As its popularity has grown, so has interest in its potential benefits. But with all the noise surrounding medical marijuana, it can be hard to know what it can actually do.
    Medications to Treat Opioid Use Disorder

    Medications for opioid use disorder (MOUD) help treat opioid use disorder by reducing withdrawal symptoms and cravings and helping to prevent relapse. As part of a comprehensive treatment plan, it is considered the gold standard of care.

    The ever-changing cannabis landscape. What to say and do when it comes to preventing use.

    Marijuana (cannabis) has recently been suggested as a potential treatment for addiction (aka substance use disorder). People in favor of its use point to its potential pain-relieving properties and lack of fatal overdose risk.  But while it may have some health benefits, more research needs to be done to confirm whether its advisable to use medical marijuana for addiction treatment. In any case, it should never be the only treatment for SUD.

    Key Takeaways

    1. Cannabis might help with withdrawal symptoms and harm reduction. Some studies suggest medical marijuana could ease painful withdrawal symptoms for opioid or alcohol use disorders. It may also serve as a harm reduction tool, offering a less dangerous alternative to opioids.
    2. There are risks and side effects to consider. Cannabis use can worsen withdrawal symptoms for some people and may lead to cannabis use disorder (CUD), especially in younger consumers. It can also affect memory, reaction times, and mental health.
    3. Cannabis is not a proven standalone treatment. While it shows potential in helping with substance use disorder, more research is needed. Medications like MOUD remain the gold standard for treating opioid use disorder and shouldn’t be replaced by cannabis.

    Potential benefits

    Can relieve withdrawal symptoms

    Research suggests that cannabis has the potential to help treat opioid use disorder. While it should not take the place of medications to treat opioid use disorder (MOUD), which are the gold standard for treatment, it might be helpful if used as a supplement.

    For some, cannabis can help relieve very painful and even fatal opioid and/or alcohol withdrawal symptoms.1 This can be helpful during a period of detox before starting MOUD, as some medications require a period of abstinence before starting.

    Though chronic cannabis use can lead to dependence and result in its own withdrawal symptoms, cannabis withdrawal symptoms are far less severe than opioid or alcohol withdrawal symptoms and not deadly. This could help reduce opioid cravings and the risk of relapse.

    May reduce overdose risk

    Cannabis can also be an effective harm reduction method for those with opioid use disorder. For example, some individuals might be open to stopping opioid use and/or receiving treatment but continue to use cannabis, which has a significantly reduced overdose risk compared to opioids. While it is possible to overdose on cannabis, which can lead to serious health issues, it is also highly unlikely to be fatal, unlike an opioid or alcohol overdose.

    Additionally, some research indicates that, for some people, medical cannabis can be effective in taking the place of addictive opioid pain medications. This might reduce the likelihood of developing an opioid use disorder in the first place.2

    Potential risks

    May worsen symptoms

    Despite its potential benefits, it’s important to note that cannabis use also comes with risks. One study found that while medical cannabis can relieve opioid withdrawal symptoms, a minority of participants found that it made their withdrawal symptoms worse.3 So, while cannabis might work for some people with a substance use disorder, it may be harmful for others.

    Can have negative health effects

    Another study found that participants who received a medical marijuana card to treat issues like anxiety and pain were more likely to experience increased symptoms of cannabis use disorder (CUD) than relief for the disorders they were attempting to treat.4 CUD affects the brain’s reward system, and the likelihood of addiction increases considerably for those who start using cannabis at a younger age.

    Additionally, marijuana can have other long- and short-term health effects, impacting reaction times, memory and learning, and mental health.  It can also lead to chronic health conditions like asthma and potentially serious mental health disorders such as schizophrenia.

    Impacts adolescents

    Cannabis can have a particularly negative effect on young people. One large review examined trials involving medical cannabis use for adolescents with conditions such as chemotherapy-related nausea or epilepsy, finding that it was typically associated with an increased risk of negative health effects.5 As a result, medical marijuana may not be an appropriate option for adolescents with opioid use disorder.

    Lack of research

    Finally, it’s important to note that much of the research supporting the use of medical cannabis for SUD relies on self-reports. Only limited research has been conducted, and, in general, only a handful of conditions have been studied thoroughly enough to determine whether cannabis can be used as a treatment option.

    Most importantly, cannabis should not be relied on as the only treatment for opioid use disorder when there are medications proven to work. Learn more about medications for opioid use disorder here.
