I think they can be, although I'd like to see specific numbers on that. Killing roughly half a million Americans a year is a high bar to clear in terms of harmful social policy changes.

But there's also a trend against long term damage here: smoking rates have been declining for decades, and the evidence overwhelmingly suggests that higher taxes and civil penalties (like fines for smoking in parks) do reduce smoking across all ages and demographics. Fewer people smoking overall means fewer people who are subject to any sort of systemic abuse. That feels like a decent tradeoff to me, especially when we consider the knock-on effects of smoking itself (individual and community health, pollution, dental outcomes, &c).
