“will medical marajuana hurt my unum disability claim”
No one really knows the answer to that question. I asked Unum for “all documentation which shows Unum’s position on medical cannabis.” But the corporation refused to respond. I would have to hire an attorney and file a lawsuit to have access to the documents I requested here:

However, if I had to guess, I would say that, considering the effort Unum expends to deny benefits, it would definitely use your treatment choice against you — not that they would ever reveal that information. But since Unum requires medical updates, you have no choice but to tell them. Unum has access to all of your medical information, so if you want to keep your marijuana use a secret, just don’t tell anybody (including your doctor).
Problem is, how are you treating your medical condition? Without proof in your medical file that you’re being treated by a doctor, insurance companies will question if you are really disabled. So, keep seeing your doctor if you can afford to, just tell him or her about all the other treatments you’re using, leaving out the use of cannabis.
All Things Chronic 
These days, I disclose as little as I can get away with, except to my wonderful PCP. I’ve told her things “off the record” that she didn’t write down, like that I was using MJ before it was legal.
She didn’t judge me because she understood my motivation. I’m so lucky to have her!
