Misleading information

I'm a chainsmoker since the time of unlabeled warning signs on the tobacco products. As per above mentioned I'd explained myself the difficulty to control the hobby or like many people will say bad habits, and discussing the criteria with the shop, the manager asked me what type of smokes do I purchase and according to the management the smokes are to light causing the problem of myself smoking too much, and obviously obeying the change of buying smokes that's more heavier it unfortunately lead to even more complications whereby I unfortunately smoke more often than with a lighter smoke. What do I do if the smoking industry are not my trade of profession?
