The largest marijuana ETF by market capitalization jumped in premarket trading after President Trump's Truth Social account published an overnight informational video highlighting the health benefits of cannabidiol (CBD), an active ingredient in cannabis derived from the hemp plant, for seniors. 

On Sunday evening, Trump's social media team published a video that began with bold text reading, "You can revolutionize senior healthcare." 

The video highlights that CBD can "restore" the endocannabinoid system, touting benefits such as reduced pain, better sleep, and lower stress. 

"When the system is restored, disease progression can slow down and years are added to your life, as well as years spent in good health," the narrator claims, adding, "Doctors often prescribe dangerous and addictive pharmaceuticals."
