I disagree, but I upvoted you. In the short term (probably 3-6 months, but actually until the novelty wears off), you are correct that more people will use it.

However, once the novelty wears off and people realize both the hazards and that said something will remain legal, people will lose interest. From my anecdotal experience, the temptation/desire of "forbidden fruit" has a strong correlation with the strength of the force maintaining the forbidden-ness all other things equal (e.g. equally addictive): the more forbidden something is, the more tempting/attractive it becomes. You could almost colloquially call it a "bad boy factor".
