SNDL Inc., a prominent player in the cannabis industry, saw its stock surge 6.01% in pre-market trading on Monday. This significant uptick is part of a broader rally across the cannabis sector, with several major companies and ETFs experiencing double-digit gains.

The catalyst for this sector-wide movement appears to be a video posted by former President Donald Trump discussing the potential health benefits of cannabidiol (CBD). This unexpected endorsement from a high-profile political figure has reignited investor interest in cannabis stocks. The video's focus on CBD's possible medicinal properties is being viewed as a positive signal for the industry's future prospects and regulatory environment.

Other cannabis stocks are also seeing substantial pre-market gains. Canopy Growth is up nearly 25%, while Tilray Brands and Cronos Group have risen by 18% and 11% respectively. Cannabis-focused ETFs are not far behind, with the Advisorshares Pure US Cannabis ETF surging by 20%. This widespread rally underscores the potential impact of changing perceptions and political attitudes on the cannabis industry's financial outlook.
