The US government has confirmed that cannabis can kill cancer cells after the drug did so in tests on mice and rats, according to the National Cancer Institute.
On its website The National Cancer Institute, part of the US department of health, said: “Laboratory and animal studies have shown that cannabinoids (the active ingredient in cannabis) may be able to kill cancer cells while protecting normal cells.
“They may inhibit tumour growth by causing cell death, blocking cell growth, and blocking the development of blood vessels needed by tumours to grow.”
