Nit, but I believe that coffee is the most used psychoactive substance in the world. Even if it is not the most used, it is surely in the top three before cannabis.

Enough evidence exists for us to consider sugar very likely to be a toxic substance, and to make an informed decision about how best to balance the likely risks with the benefits.
