- Recreational and medical use of marijuana, CBD, and cannabis products are legal in many states across the US. However, there are issues that doctors, nurses, and other healthcare license holders should be aware of before they do smoke weed, pot, hash oil, honey oil, or use medical marijuana or other psychoactive THC products. Licensed healthcare workers are subject to more restrictive marijuana use standards than the general public, even with a medical card and even in legal states, such as California, Colorado, and Washington. This guide helps you avoid triggering license board or employer disciplinary actions that put your career at risk., Can Physicians or Nurses Smoke Marijuana? - Analysis of the laws governing cannabis use by healthcare professionals., Health Care, 2024

Marijuana remains illegal under federal law, even with a medical card in legal states, such as California, Colorado, and Washington.

- Assembly Bill 2138 became effective July 1, 2020. This groundbreaking new law reduces barriers to obtaining professional licenses, expanding opportunities for those with conviction records, reducing recidivism rates, and increasing the transparency and predictability of licensure behavior. Almost 30 percent of the jobs in California (in approximately 1,773 occupations) require certification, licensure, or clearance from a DCA oversight agency or board. AB-2138 restricts the discretion and licensure criteria of 37 licensing boards within the Department of Consumer Affairs for denying, suspending or revoking licensure due to criminal convictions or alleged misconduct. Only 3 occupational boards are excluded from the reforms., Analysis of AB-2138: CA Professional license criminal record changes, Criminal Justice, Health Care, Construction, 2020

- The California Department of Consumer Affairs (DCA) is the consumer protection agency that licenses and regulates more than 3.5 million licenses in over 280 license types.

The DCA has jurisdiction over 40 professional and occupational licensing boards, from the Board of Registered Nursing and the Medical Board of California to the Board of Accountancy and Board of Pharmacy., Author, Guide to California Department of Consumer Affairs Investigations, Chudnovsky Law, Healthcare, Medical Malpractice, Finance, Real Estate, 2026
- In many cases, physician disciplinary actions begin with something innocuous – perhaps a patient’s record request or letter in the mail requesting basic information. The letter or email may come from the Department of Consumer Affairs (DCA) Division of Investigation, not the Medical Board of California. Many unsuspecting physicians or their office staff may be unaware this indicates a Medical Board investigation., Author, Guide to Medical Board Investigations and Disciplinary Actions, Chudnovsky Law, Healthcare, Medical Malpractice, 2026
- As a nurse, you have dedicated your life to being a healing caregiver in a rewarding but demanding career. Dealing with allegations of misconduct that put your ability to work at risk can be stressful. While anyone can make a mistake, as a nurse, a mistake or even an unjust complaint from an unhappy patient or coworker can trigger a California Board of Nursing investigation and dangerous disciplinary actions. If you are facing a nurse complaint, investigation or disciplinary action, it is crucial that you understand the process and when to obtain expert legal counsel. Dealing with the California Board of Registered Nursing (BRN) and the California Board of Vocational Nurses and Psychiatric Technicians (BVNPT) involve risks you need to be aware of., Author, Guide to Board of Nursing Disciplinary Actions and Complaints, Chudnovsky Law, Healthcare, Medical Malpractice, 2026
- California enacted a new misconduct disclosure law for physicians on July 1, 2019. The “Patient’s Right to Know Act” Senate Bill 1448 was drafted by Senator Jerry Hill. This groundbreaking law requires that doctors facing a probationary discipline action obtain a signed disclosure form from all patients before their next appointment. This is in addition to a Medical Board of California iOS app announced July 2018 for consumers that pushes out license alerts to consumers whenever their physician has received a license disciplinary action or change in license status., Author, Physician Guide to California Patient’s Right to Know Act SB1448, Chudnovsky Law, Criminal Justice, Health Care, 2024

- If you’ve been charged with DUI or DWI, you are innocent until prosecutors prove guilt beyond a reasonable doubt. That is a very high burden of proof for the DA. You can beat a DUI charge by identifying legal flaws or doubts about any key evidence required to convict under VC 23152. Inaccurate breathalyzer BAC tests, police errors, medical conditions and dozens of DUI defenses can be used to fight a DUI and get DUI cases dismissed or charges reduced. Here we review how to beat a DUI case using the 20 best DUI defenses. And they’re all distilled from fighting thousands of DUI cases.
