Trump's decision to move marijuana to Schedule III could ease taxes and expand medical access, but industry leaders warn it may also trigger stricter federal oversight and new legal risks.

Trump's executive order to expedite reclassifying cannabis means wider access to marijuana and that it could be used like any other prescribed drug during the workday.

Experts told ABC News that reclassification of the drug would open the doors to more scientific research by removing current major barriers and may also reduce stigma.

The executive order would reclassify marijuana from a Schedule I to a less dangerous, Schedule III drug. Business leaders say the move is "long overdue" and it would open the door for more benefits for businesses and consumers.
