ELI5: Texas is running out of lethal injections- how/why, can't they order/make more?
gpt
The pharmaceutical companies that make the drugs for lethal injections no longer are interested in continuing their production. Many see it as bad PR for the company as a whole or for some drugs that they sell since they can be used for legitimate medical purposes as well as in executions. Would you feel comfortable using a substance used in executions regardless of if your doctor ensured that it was ok at "this level"? That kind of association is bad for business. 

Some states are looking into hiring smaller firms to custom make the drugs for them.
