In years gone by, these FTSE 100 shares could rely on the addictive nature of their products to keep profits rolling in. That made them some of the hottest safe-haven shares in town in uncertain times like these. Smokers would battle hell or high water to keep buying their favourite cigarette brands, economic downturn or not.I believe that things are likely to prove different for Big Tobacco during this global recession though. This is why neither FTSE 100 firm has seen safe-haven demand for their shares take off in 2020. Worldwide tobacco usage has been on a sharp slide for a decade now, on rising health concerns. It’s also likely the Covid-19 pandemic will encourage even more smokers to stub out the habit, as some point to higher infection rates among tobacco users.More smoking bansIn fact, Jordan brought in a fresh smoking ban in recent days on the back of a possible correlation. The Middle Eastern country is one of the biggest tobacco consumers in the world, so it could be a serious blow to British American Tobacco and Imperial Brands. The FTSE 100 giants can expect regulatory action (like smoking bans and plain packaging requirements) to be stepped elsewhere up in the months ahead too.Legislative action like this is proven to have had a devastating impact on tobacco demand. In the UK, stick sales have plummeted by around 20m a month since plain packaging rules were introduced three years ago, according to the Tobacco Control Research Group. This compares with a drop of around 12m a month before the rules came in.I sold my Imperial Brands shares several years ago on the steady decline of its traditional combustible products. Questionmarks over future demand for their new-age vaping products like e-cigarettes encouraged me to get out too. And my decision has proven to be the correct one, as Imperial Brands’ share price has tanked 60% since I sold out.This share, along with FTSE 100 rival British American Tobacco, have the capacity to destroy your wealth in the years ahead. So I’d avoid them at all costs, and buy other Footsie shares instead. See all posts by Royston Wild Simply click below to discover how you can take advantage of this.
