Any where to get cbd and or thc products in Norwich?

Hi, i’m sorry if this offends anyone. I am a medical cann user (for chronic pain and nausea) who is visiting a friend and will be staying with them for at least 2 weeks. I am unable to get my address for my prescription changed to my friends. Would there be any plugs or anyone who is able to point me in the right direction?

Thank you so much.
