This study looks at how using cannabis (a plant) and cannabinoids (parts of the cannabis plant) might help or hurt cancer patients. It includes 2,000 people with breast, colorectal, melanoma, non-Hodgkin lymphoma, or non-small cell lung cancer. These patients are getting cancer treatments like chemotherapy (special drugs to kill cancer) or immune checkpoint inhibitors (ICIs), which help the body's defense system fight cancer.
The study lasts for one year, and participants will fill out surveys and have their medical records checked every month to see how they are feeling and if cannabis is affecting their symptoms.
- Study Duration: 1 year

Participants can join from home using an email. They must live in the U.S. and not be in a hospice. The study is not for pregnant people or those in other supportive treatment trials. There's also an optional smaller study at select sites for non-small cell lung cancer patients receiving special treatments.
