Questions and Answers About Cannabis”
Have any preclinical (laboratory or animal) studies been conducted using Cannabis or cannabinoids?
Preclinical studies of cannabinoids have investigated the following:
Studies in mice and rats have shown that cannabinoids may inhibit tumor growth by causing cell death, blocking cell growth, and blocking the development of blood vessels needed by tumors to grow. Laboratory and animal studies have shown that cannabinoids may be able to kill cancer cells while protecting normal cells.
A laboratory study of cannabidiol (CBD) in estrogen receptor positive and estrogen receptor negative breast cancer cells showed that it caused cancer cell death while having little effect on normal breast cells. Studies in mouse models of metastatic breast cancer showed that cannabinoids may lessen the growth, number, and spread of tumors.
A review of 34 studies of cannabinoids in glioma tumor models found that all but one study showed that cannabinoids can kill cancer cells without harming normal cells.
A laboratory study of cannabidiol (CBD) in human glioma cells showed that when given along with chemotherapy, CBD may make chemotherapy more effective and increase cancer cell death without harming normal cells. Studies in mouse models of cancer showed that CBD together with delta-9-THC may make chemotherapy such as temozolomide more effective.
Something which has apparently been known in Cancer Research circles, has been formally announced to the public.

- Cannabis , also known as marijuana, is a plant grown in many parts of the world which produces a resin containing compounds called cannabinoids. Some cannabinoids are psychoactive (acting on the brain and changing mood or consciousness) (see Question 1).
- The use of Cannabis for medicinal purposes dates back to ancient times (see Question 3).
- By federal law, the possession of Cannabis is illegal in the United States outside of approved research settings. However, a growing number of states, territories, and the District of Columbia have enacted laws to legalize medical marijuana (see Question 1).
- In the United States, Cannabis is a controlled substance requiring special licensing for its use (see Question 1 and Question 3).
- Cannabinoids are active chemicals in Cannabis that cause drug -like effects throughout the body, including the central nervous system and the immune system (see Question 2).
- The main active cannabinoid in Cannabis is delta-9-THC. Another active cannabinoid is cannabidiol (CBD), which may relieve pain, lower inflammation, and decrease anxiety without causing the “high” of delta-9-THC (see Question 2).
- Cannabinoids can be taken by mouth, inhaled, or sprayed under the tongue (see Question 5).
- Cannabis and cannabinoids have been studied in the laboratory and the clinic for relief of pain, nausea and vomiting, anxiety, and loss of appetite (see Question 6 and Question 7).
- Cannabis and cannabinoids may have benefits in treating the symptoms of cancer or the side effects of cancer therapies. There is growing interest in treating children for symptoms such as nausea with Cannabis and cannabinoids, although studies are limited (see Question 7).
- Two cannabinoids (dronabinol and nabilone) are drugs approved by the U.S. Food and Drug Administration (FDA) for the prevention or treatment of chemotherapy -related nausea and vomiting (see Question 7 and Question 10).
- Cannabis has been shown to kill cancer cells in the laboratory (see Question 6).
- At this time, there is not enough evidence to recommend that patients inhale or ingest Cannabis as a treatment for cancer-related symptoms or side effects of cancer therapy (see Question 7).
- Cannabis is not approved by the FDA for use as a cancer treatment (see Question 9).
