The answer is: more than we can list here, and probably more than you think.
Business & Professions Code 2052 makes it a crime to practice medicine without a license in California. But this law covers far more territory than just doing a doctor's or nurse's job without the proper professional license.
For example, California "unauthorized practice of medicine" charges could be brought against you if you offer any of the following services without a license:
- Hypnosis for treatment of physical or mental conditions like obesity or insomnia,
- Acupuncture, and
- California medical marijuana consultations.
In addition, it is a violation of California's unauthorized practice of medicine laws to own or otherwise get a share of profits from a medical practice, if you are not a licensed medical professional.
