San Diego, CA – Marijuana and prescription drug interactions are increasing. In response, seventeen local pharmacies are taking the lead in a project to provide much-needed consumer information about marijuana, THC, CBD and interactions with prescription medications. Lack of knowledge and misinformation can lead to hospital visits. With this project, up to 12,000 people will receive information about drug interactions and cannabis products. This project is one step in developing campaigns that increase knowledge and awareness around this issue.

Now, several local pharmacists, including Dr. Seung Oh, the pharmacy supervisor at Sharp Rees-Stealy Santee Medical Center, want you to also be cautioned that your medications could lead to potentially harmful reactions when combined with using marijuana, also known as cannabis.

US Researchers Find Increased Likelihood of Arrhythmia Hospitalization in Youth With CUD

Cannabis Use Disorder (CUD) was associated with a 47%-52% increased likelihood of arrhythmia hospitalizations in the younger population. The risk of association was controlled for confounders including other substances. Atrial fibrillation was the most prevalent arrhythmia raising concerns for stroke and other embolic events. This large national study compared 570,000 patients ages 15-54 who were admitted to the hospital between 2010-2014 for a primary diagnosis of arrhythmia (irregular heart rate). These patients were compared to 67,662,082 patients who did not have arrhythmia in the hospital.
