Hello princeminer22,
This has been a bug for many seasons already where if you got an afk captcha the drugs will disappear.
First solution will be going into your cell and and change the server to sbd or any server except prison, after that you just relog to prison and check if your drugs are still not appearing.
Second method will be doing /spawn and /c home until the drugs appear.
Third method will be going to the center of your farm and make a platform 4-5 blocks high on the center of your farm and do /c sethome {name} and then go /spawn and just do /c home {name of the sethome}. (This works everytime for me)
Hope this helps you.
Thread solved, Requesting Thread lock.
