" can I still get a medical marijuana card?"
Yes, you can still get your medical recommendation through HelloMD. You will need a government issued ID to prove who you are and your age however. Also, you need to be within CA during your consultation. The only issue you may encounter is various different policies that different dispensaries have. Some storefront dispensaries will not accept an out of state ID for instance. You will most likely encounter less issues with a delivery service, but it is up to you to do your homework to find out where to go to purchase your medicine without a state issued ID.
Hope this helps!
