NEW research reveals the drug's main psychoactive ingredient - tetrahydrocannabino (THC) - could be responsible for its success in shrinking tumours.

They then targeted the tumours with doses of the cannabis compound and found that two cell receptors in particular were responsible for the drug's anti-tumour effects.

So they have done testing (more at link) & yes it does shrink tumors but... we won't let anyone use it until we can find a synthetic (which can then be patented) & they can then earn lots of Pharma $$$$ from their 'cure'

"Our research uses an isolated chemical compound and using the correct concentration is vital," Dr McCormick said.

"Cancer patients should not use cannabis to self-medicate, but I hope that our research will lead to a safe synthetic equivalent being available in the future."
