If caffeine is bad, why people are selling it?

Same reason people sell alcohol. It can be enjoyed in small doses. While doing it safely.

It is bad if one drinks too much.

Doctors currently advise that the equivalent of one standard espresso per day is safe.

It's insidiously addictive - the more you drink, the less wake-up effect it has - but it'll still keep attacking that liver.

Demand is high, people consume it and government gets tax, people get employment. Same as alcohol, cigs and other drugs. Once the demand goes down, the supply would.

Oh, the millions who have died from the scourge of that bean,you can't even get into rehab.

And the crimes committed.for one more cup🤣🤣

Bad drug? It doesn't kill you like smoking or alcohol... Oh wait... It has.

Nuuuuu it's good. I like it

Cause it's less bad than some of the others maybe.
I dunno how you want to rank the drugs. Some of the "schedule" stuff doesn't make any sense.

Overuse of it is bad. In moderate amounts, it’s generally not a problem.
