Washington Marijuana Retailer Sued Under My Health My Data Act for Website Pixel Use

by Sam Castic and Felicity Slater

A class action suit was recently filed against the companies that operate Uncle Ike's, a Seattle-area marijuana retailer. The suit filed in Washington federal court alleges common law tort claims, ECPA claims, and a claim under the My Health My Data Act (‘MHMDA’ or ‘the Act’). 

Unlike the MHMDA claims that have been brought to-date against other companies that seem to allege MHMDA violations as something of an afterthought, the complaint brought against Uncle Ike’s makes a number of allegations in support of the MHMDA claim. In particular, the complaint alleges that:

  • the Uncle Ike's website accepted online purchases of marijuana products, including medical marijuana products, and permitted medical marijuana card appointment scheduling;

  • information about these transactions was shared with Google via pixels and other tracking technologies; and

  • Uncle Ike’s online privacy policy said that sensitive personal data would be kept private.

To bring a claim under MHMDA, plaintiffs must demonstrate that they have suffered a "harm to business or property" under the Washington Consumer Protection Act (WCPA) that was caused by defendant's violation of MHMDA. Here, plaintiffs allege that Uncle Ike’s disclosure of their sensitive information without consent has caused “numerous injuries,” including “invasion of medical privacy,” “diminution of value of the[ir] Sensitive Information,” and “continued and ongoing risk to their Sensitive Information.” The court’s receptivity to these allegations of harm will be significant and may create a playbook for future MHMDA plaintiffs.

If your company has a website or app that sells even tangentially health-related products, shares medical or health related content, or allows appointment scheduling for medical appointments, this lawsuit is a good reminder to:

  • Assess which data involved in these activities is "health data" under laws like the MHMDA; and

  • Confirm that appropriate consents and authorizations are obtained before that data is "sold" to third parties, including for targeted advertising purposes (under MHMDA, the required authorizations may be impractical to obtain in the website or mobile app context).

Fourth Circuit Publishes Landmark Ruling on 21st Century Cures Act “Information Blocking”

By Cameron Cantrell and Kate Black

On March 12, 2025, the Fourth Circuit Court of Appeals ruled that (1) the information blocking prohibition in the federal 21st Century Cures Act (“Cures Act”) was plausibly violated when an Electronic Health Record (EHR) provider blocked bot access to its systems without sufficient justification, and (2) this violation may support a Maryland state law unfair competition claim, despite the Cures Act not having its own private right of action. This decision notably appears to be the first Circuit Court decision concerning the information blocking prohibition and, for parties subject to the rule, raises the risk that information blocking may be enforceable through a de facto state privacy right of action.

New York Legislature Passes Extraordinarily Restrictive Health Data Privacy Bill

By Mike Hintze and Felicity Slater

Last year, we wrote about a proposed New York State law that would have significant impacts for entities that process health and wellness related data. That bill failed to pass before the 2024 legislative session ended. But today, in the early days of the 2025 session, the New York State legislature has passed Senate Bill S929 (SB S929), which is essentially unchanged from last year’s bill.

By Mike Hintze and Felicity Slater 

On November 7, 2024, the Michigan legislature introduced Senate Bill 1082 / House Bill 6077, the Reproductive Data Privacy Act (the “RDPA” or the “act”).

Washington My Health My Data Act - Part 4: Effective Dates

By Mike Hintze

Yesterday the amended Senate version of the Washington My Health My Data Act was approved by the Washington State Legislature. Now that it is a near certainty the Act will become law in its current form, entities subject to the Act need to start preparing to comply. The key factor in determining deadlines for having compliance measures in place is the effective date of the Act. The Act purports to come into effect on March 31, 2024 (and for small businesses, three months later on June 30, 2024). However, contrary to stated legislative intent, and due to what one can only conclude is, at least in part, a drafting error, some of the key substantive provisions of the Act may come into effect much sooner than expected - as soon as July 2023.

Washington My Health My Data Act - Part 3: The Scope of Entities and Consumers Captured by the Act

By Mike Hintze

The Washington My Health My Data Act applies to “regulated entities” that collect or process “consumer health information” from “consumers.” Part two of this series addressed the definition of “consumer health data” and how that definition results in a scope of applicability that is far beyond what we might typically think of as sensitive health data. But the other two above-quoted defined terms – “regulated entity” and “consumer” also result in a very broad (and in some ways surprising) scope and impact.

Washington My Health My Data Act - Part 2: The Scope of “Consumer Health Data”

By Mike Hintze

The substantive requirements of the Washington My Health My Data Act apply to collection, use, and disclosure of “consumer health data.” While there are a few important exclusions, the stunning breath of that term's definition, means that it will be difficult to safely conclude that any category of personal data is out of scope of the Act. As a result, it is inaccurate to refer to the Washington My Health My Data Act as a “health data privacy law.” On the contrary, it is, in effect, a generally-applicable privacy law.

The Washington My Health My Data Act - Part 1: An Overview

By Mike Hintze

The Washington My Health My Data Act will become the most consequential privacy legislation enacted in 2023. The sweeping scope and extreme substantive obligations, combined with vague terms and with a full private right of action, make this Act extraordinarily challenging and risky for entities seeking to comply with its requirements.
