Who Will Be The First Know PED User To Be Voted Into The Hall Of Fame ?

Willie Mays used amphetamines throughout his entire career and they are considered a PED by MLB. Amphetamines were not banned by MLB at the time Mays used them by name but he bought and sold them illegally and so their use was banned because he used them illegally. If you are asking who is the first player that admitted to or tested positive to steroids my guess is probably Barry Bonds. I can't imagine they will keep the greatest player in decades and possibly the greatest player of all time out of the Hall of Fame forever.

That'll never happen, end of story.

There is no way that someone, who gains an unfair advantage to boost their performance by using PEDs should be allow in the Hall of Fame. It casts a big black mark on their resume. If any player(s) cheat to gain that unfair advantage, then pay the consequences later when their names appear on the HOF ballot.

In other words, their numbers might scream out "Hall of Fame!" However, it'll be seen with an asterisk right next to it due to steroids, which makes it way lest impressive than it really is. And that means, no Hall of Fame.

Maybe Hank Aaron can be the first PED user

If you mean someone playing from this decade or two I would say David Ortiz

Already happened.

1965.

Pud Galvin elected to the HOF.

In 1889 he used a product called the Brown-Sequard Elixir, which, among it's other ingredients, contained monkey testosterone.

My guess is that eventually the torch-carrying crowd will die out and we will see someone who either admits to using or who tested positive inducted.

Keep I mind that the HOF has not yet introduced any sort of policy that would automatically disqualify a known user from induction. My guess is it will end up being someone like Andy Pettitte, who admitted to doing so only for a short time while recovering from an injury. Seems like the public has sort of given him a pass. Maybe the BBWAA does so as well.

Hank Aaron admitted to trying amphetamines. There are probably more than a dozen amphetamine users in the HOF, and probably a few steroid users (from as early as the 60's, when steroids were readily available to athletes and legal).
