Big welcome to Swaves! I know that you l̶o̶w̶b̶a̶l̶l̶ market a lot, but do you have a goal already in the clan? Fighting, event, old and good discussions?
My two cents to for the subject:
I agree with Ele, addicted people won't stop buying their thing just because it got expensive, that's not how they work. It will create a new type of problem: In debt addicted people, they will take loans, they will borrow, they will sell things in their houses, same happened here in Brazil with cigarettes, only a few companies still around, but smokers didn't stop buying. Now that the cigarette price is back to its normal people are more likely to start smoking than before, when nothing happened.
