Not really. The biggest issue with medical marijuana is that people wish to ingest the raw plant, preferably by smoking it. Smoked marijuana is not approved for medical use in the U.S. Marinol (synthetic THC) is approved; Sativex (Cannabinoid extracts) is seeking approval.
"not that Jamaica has had two recognized cannabis medicines for cannabis for some time."
Canasol and Asmasol are both extracts, and are approved for use in Jamaica (not FDA approved). Smoking marijuana (ganja) in Jamaica for any reason is illegal.
"My sister has MS and studies now show that cannabis can reverse damage."
Reverse the damage? You wouldn't have a link to that "study", would you? I tried Google with no luck. I know that marijuana has been touted to reduce spasticity, totally contrary to the largest study ever done -- which showed no effect.
The 1999 National Academy of Science/Institute of Medicine Report concluded that smoked marijuana does not have a role in the treatment of MS.
"Based on the studies to date, it is the opinion of the National Multiple Sclerosis Society's Medical Advisory Board that there are currently insufficient data to recommend marijuana or its derivatives as a treatment for MS."

"What a sad joke."
The sad joke is that the people who wish to legalize marijuana for recreational use are using the sick and dying as pawns. "Medical marijuana" is the red herring hiding their real goal. They couldn't care less about MS patients.
