You can get a recommendation for a card in Massachusetts through a doctor licensed within your state and in MA you are required to see that doctor in person. Within your state the following conditions will allow you to obtain a legal recommendation:
MS (Multiple Sclerosis)
After getting your recommendation you will then need to register with the state which is an online process but requires proof of rec, ID photos and a PIN number. You will need to be approved by the Medical Use of Marijuana program.
Unfortunately you can only get a recommendation thorugh HelloMD if you are within the state of California.
I hope this helps!
