The author concludes that marijuana use can cause cancer. This is because the THC in marijuana has been found to inactivate herpesviruses in a study, and inactivated herpesviruses can convert healthy cells to cancer cells.

In order for marijuana to cause cancer, the author must assume that the studies cited reflect normal biological circumstances in humans—in other words, that this process could happen outside of a lab. The author must also assume that the cancer-causing effect of THC isn’t offset by some other protective factor in marijuana.

This reinforces the study that the author cites by telling us that the result wasn't a fluke. That means this strengthens the argument rather than weakening it.

While THC alone converts healthy cells to cancer cells, other ingredients in marijuana offset this effect. This undermines the author's conclusion that marijuana causes cancer due to the effects of THC.

If anything, this gives another reason why marijuana may cause cancer: THC weakens the body’s immune system, leaving it susceptible to cancer threats. This only strengthens the argument.

We care about the THC that actually appears in marijuana. The potential uses of modified THC are irrelevant to whether using marijuana can cause cancer.

This is a niche scenario that doesn’t weaken the connection between marijuana and cancer. We’re specifically interested in whether marijuana use can cause cancer via herpesviruses, and this doesn't help us with that.
