There is some promising evidence that CBD use may help people to quit smoking. A pilot study posted to Addictive Behaviors found that smokers who used an inhaler containing the compound CBD smoked fewer cigarettes but did not have any additional craving for nicotine.
Another similar study posted to Neurotherapeutics found that CBD may be a promising substance for people who abuse opioids.
Researchers noted that some symptoms experienced by patients with substance use disorders may be reduced by CBD. These include anxiety, mood symptoms, pain, and insomnia.
These are early findings, but they suggest that CBD may be used to avoid or reduce withdrawal symptoms.
