My grandmother is not okay with me working on a marijuana farm

There are times when trying to explain something to an elderly person is essentially like beating your head against a brick wall.

No matter what you present as a good argument they counter it with the same statement or opinion.

This is the concern I have been facing as of late. After university I moved in with my Grandmother to save a decent amount of money while I paid my student loans and looked for a decent job. This was helpful to her as well because I was always running errands and helping with household chores. As I was looking for a job I kept noticing ads for a local cannabis farm that was hiring workers. I figured I could do this part time and gain a bit of money to help pay my loans faster. They were starting people out above minimum wage and I wanted to see what it was all about. Well, I made the terrible mistake of mentioning this to my Grandmother and I might as well have told her I was robbing a bank. She started spouting about me being a serious drug dealer and that she would not allow me to stay in her property. I tried to explain that it was a legal place of business and that the marijuana farm where I would be now working only grew cannabis for people who needed it for medicine. I also tried to explain the difference between what you buy on the street corner and what is available to individuals to help with symptoms associated with their particular conditions. Again, she said that she would not ever condone anything that had to do with growing pot and that I would have to go elsewhere if I took that job.
