Scientific American posts an article on new treatments for MS and someone posts this.
Cannabis oil deals effectively with MS without any of the side effects. There are now CBD/CBN oils that have NO PSYCHOTROPIC EFFECT, no "high". The federal government holds medical patents on a plant it outlawed for having "no medical value" while pouring billions into the pockets of pharmaceutical companies that dominate Medicare/Medicaid. Fight for your rights to use non-narcotic, natural remedies. Tell the Attorney General to respect state legislation regarding cannabis use and research. Tell the White House to release all patients and non-violent cannabis prisoners.
Do you have evidence refuting the claim that cannabis can be an effective MS treatment? Hint: Pub Med is your friend: http://www.ncbi.nlm.nih.gov/pubmed/22791906
There are, no doubt, many studies completed or underway to this effect (see the several cited articles on the sidebar, which confirm that ongoing research in this field is vigorous). Looks like your friend was essentially correct.
