The authors from the Complutense University in
Madrid, working with scientists from other universities, found that the active component of marijuana, tetrahydrocannabinol (THC), causes cancer cells to undergo a process called autophagy -- the breakdown that occurs when the cell essentially self-digests.
The research, which appears in the April edition of US-published Journal of Clinical Investigation, demonstrates that THC and related "cannabinoids" appear to be "a new family of potential antitumoral agent."
