You might expect a simple answer from expert people in domain, but the reality is that most governments levy taxes on tobacco products, including excise taxes, value added taxes (VAT) or general sales taxes and import duties. Of these, tobacco-product excise taxes are most important for achieving the health objective of reduced tobacco consumption since they are uniquely applied to tobacco products and raise their prices relative to the prices of other goods and services. That's why if you plan or have a tobacco company, for not losing the profit you can easily switch the tobacco production to a pharmaceutical company supplier with tobacco plants or why not a pharmaceutical company itself.
