A place called Washington, D.C., is having a special time for buying medical marijuana without paying extra money (it's called a tax holiday). They are doing this because of a popular day called 4/20. Also, they are making it easier for people to use their cards to buy medical marijuana and stopping others from selling it illegally. This is all happening in different parts of the United States too, where they are trying to remove records of people who were punished for using marijuana before. Read from source...

1. The headline is misleading and sensationalized. It should be more factual and informative, such as "Medical Marijuana Tax Holiday Extended in D.C., States Take Steps to Clear Marijuana Convictions". This way, readers can better understand the main points of the article without being distracted by the 4/20 reference or the Benzinga promotion.
2. The article does not provide any context or background information on why D.C. decided to extend the tax holiday or how it will benefit patients and dispensaries. A brief history or explanation of the previous policy would help readers grasp the significance of this change. Additionally, some statistics or data on the medical marijuana program in D.C. would add credibility and relevance to the article.
3. The article mentions Maryland's alignment with the six-year registration card validity without explaining how it compares to other states or what impact it will have on patients. A comparison of different state policies on medical marijuana registration and renewal would be helpful for readers who want to learn more about this topic.
4. The article promotes Benzinga's Cannabis Capital Conference without any disclosure or separation from the main content. This creates a conflict of interest and undermines the journalistic integrity of the article. A more appropriate way to mention the conference would be in a separate section at the end of the article, with a clear disclaimer that it is a sponsored event by Benzinga. Alternatively, the article could focus on other cannabis-related events or conferences that are not affiliated with Benzinga.
