Reliance on anecdotes is driven by paucity of statistically meaningful data. Reminding people that the former is not as good as the latter is unhelpful. Anecdata is still data.

You'd be surprised how common it is for people to take THC in one form or another. It is literally meaningless to pull two stories together and derive a causation.
