Does nausea and appetite loss qualify in Colorado?
Yes. The Colorado Medical Marijuana Registry lists Severe nausea as a qualifying condition. A Colorado-licensed provider still has to evaluate you and agree that cannabis is appropriate.
About nausea and appetite loss
Severe or persistent nausea and appetite loss can come from chemotherapy, HIV/AIDS, gastroparesis and other conditions, and can lead to dangerous weight loss.
Stronger evidence. There is conclusive evidence that oral cannabinoids treat chemotherapy-induced nausea and vomiting, and limited evidence that they increase appetite and reduce weight loss in HIV/AIDS.
Symptoms Colorado patients most often hope to ease:
- Nausea and vomiting during chemotherapy
- Loss of appetite
- Unwanted weight loss
- Food aversions and changes in taste
- Nausea that does not respond to standard medicines
Before you start. Heavy long-term cannabis use can rarely cause cannabinoid hyperemesis syndrome, which causes repeated severe vomiting. Cannabis is not recommended for nausea during pregnancy because THC can reach the baby.

Frequently asked questions
Do I need medical records for nausea and appetite loss?
Helpful records include: records of the condition causing your nausea, such as a cancer treatment plan or GI diagnosis; a list of anti-nausea medicines you have tried and how well they worked; notes on weight changes, eating difficulties and how often you are sick. Many patients are still evaluated on their history alone, and your Colorado provider will tell you if more is needed.

The provider visit takes about 15 minutes. 1-3 business days for complete online applications.
Can I renew online in Colorado?
In most cases, yes. You can renew online within 30 days of your expiration date. Each renewal needs a brand-new provider certification and the application fee.
