Seattle Seahawks superstar Richard Sherman is "ill-informed" when it comes to Adderall ... and should immediately stop pressing the league to un-ban the drug before someone gets hurt ... this according to the NFL.
The league has released an aggressive statement in response to Sherman's recent pro-Adderall comments -- in which Sherman says the NFL should "allow it" because "about half the league takes it."
A rep for the NFL tells TMZ ... "The comments are ill-informed and inaccurate. Adderall is easily detected under current testing and will result in a suspension absent an approved therapeutic use exemption."
The rep continues, "If his statement were true, we would be seeing many more positive tests and suspensions."
"More importantly, his comments are irresponsible, as they ignore the serious medical risks and documented public health crisis associated with the improper use of Adderall and similar drugs.”
FYI -- Sherman was nearly suspended last year when he tested positive for Adderall -- but he appealed his case and won, saying there were errors in the testing.
