The UK taxed tobacco to high heaven and I don't think it did much to actually curb use. It's subject to the usual 20% VAT, plus an extra 16.5%, plus a flat £6.33 on 20 packs, so well over half of the sale price of tobacco is just tax.
Tobacco smoking has been on a downward trend since at least the 70s, from 50 to 13%, and taxes have steadily gone up since then in real terms, but I'm surprised to see that the period when the government raised taxes the most is about the only flat part of the curve.
The people I know that would be affected by this just get duty free from corner shops under the table now. Last I heard it's around 8 quid for 50g of rolling tobacco instead of £38 buying legit.
Wouldn't be surprised to find out they smoke more than they used to with it being less scarce.
