This is a list of Schedule I drugs under the Controlled Substances Act for the United States. Required findings for drugs to be placed in this schedule: [1]

1. The drug or other substance has high potential for abuse.
2. The drug or other substance has no currently accepted medical use in treatment in the United States.
3. There is a lack of accepted safety for use of the drug or other substance under medical supervision.

I know this is such bullshit man how could anyone argue that weed is any of those 3 things. well i guess you could consider it "high potential for abuse" but whatever smoke weed everyday
