Cronos Group Inc. (CRON) witnessed a remarkable pre-market surge of 20.43% on Monday, as cannabis stocks across the board experienced significant gains. The dramatic uptick comes amid reports that President Trump is considering reclassifying marijuana as a less dangerous drug, potentially transforming the landscape for the cannabis industry.

The pre-market rally wasn't limited to Cronos Group. Other major players in the cannabis sector also saw substantial increases, with Canopy Growth up nearly 14%, Tilray rising around 12%, and Aurora Cannabis climbing 9%. This industry-wide boost underscores the potential impact of the proposed policy change on the entire marijuana market.

The catalyst for this surge appears to be President Trump's recent comments at a high-profile fundraiser. According to sources present at the event, Trump expressed interest in reclassifying marijuana as a Schedule III drug, a move that could significantly ease restrictions on the industry and potentially lead to tax breaks for cannabis companies. This potential shift in federal policy, coupled with the cannabis industry's substantial political contributions, has ignited optimism among investors and fueled the pre-market rally.
