How many people are arrested but never go to trial or end up with no conviction? She isn't a "felon" unless she has been convicted. If she has been convicted of a drug related felony, I don't see any alternative to termination.

I don't know WHERE you are. I don't know if she's been arrested and/or found guilty. I'd suggest that YOU read your employment policy if she's YOUR employee and follow company policy.

No idea where in the world you are to know which laws may apply. And we don't know what any employment contract may say as well.
For the moment, being arrested does not make someone a convicted felon. But most employment is at-will.

In most states an employee can be fired for any reason. But the employer would have good cause if the employee lied on their application.

Of course she can be terminated, for this and almost any other reason.
