Drug info - DEA's reason for why DMT is illegal?

[CoryInJapan]

So I decided to try and find the reason why exactly DMT is illegal Plus its a schedule 1 substance

Schedule 1=(A) The drug or other substance has high potential for abuse.
I highly dont that

(B) The drug or other substance has no currently accepted medical use in treatment in the United States.
This is an excuse to make a substance illegal o_O

(C) There is a lack of accepted safety for use of the drug or other substance under medical supervision.

Again,why does a substance have to have medicinal value to be legal.
Tobacco as far as I know has no medicinal value
if it does its wouldn't even be worth the health risk.
and to me this seams like Tobacco fits the description on a schedule 1 substance.

Can anyone tell me or link me to a real reason as to why this sunstance is illegal explained by the DEA?

I couldn't find nothing but why other people say its illegal in video's and so forth.

Does the DEA actually explain why its illegal?
