To find grassroots cancer cures Rick Simpson discovered, recalling a mid 70s radio show that THC cures cancer, see free Run FROM the Cure at PhoenixTears.ca or YouTube. 

The formula is simple but finding the right raw material may be difficult. Basically:
ONE POUND of high grade Indica bud makes
TWO OZ Rick Simpson Oil & can cure cancer (and many other maladies) in
THREE to FOUR months. 
He recommends a maintenance dose for longevity.

*** Exercise extreme caution ***

Rick warns not to try to make it unless well informed: dangerous solvents.
Legalize it, he says, let doctors decide doses. Some already do.

Make it without dangerous solvents?  Ask dispensaries.

He cautions: must follow protocols that can make one comatose; a caregiver should try it to understand strong effects. Its not a quick fix - takes a couple of months.

Rick eventually got to the point that he'd usually not supply Rick Simpson Oil to folks who had submitted to chemo/radiation, conventional cancer treatments.
