Yeah, well said.
I wonder what the evidence is behind the BLF saying that cannabis cigarettes are 20 times more harmful than tobacco ones. Are they simply arguing from the concentration of carcinogens found in cannabis smoke, which is a lot higher than carcinogens found in tobacco smoke, and then deducing from that that cannabis is more harmful? That's dodgy reasoning if so because, as you say, cannabis also contains anticarcinogens, and so you get studies like the 2006 one funded by federal health and drug enforcement officials in the US, showing that, statistically, chronic marijuana smokers are at no greater risk of lung cancer than non-marijuana smokers and might even be at less risk, with marijuana providing protective benefits against cancer. link
