Retail displays, positioned alongside everyday confectionery and sweets, were a key component of making cigarettes attractive to recruit young smokers, she said.
Tobacco companies have said they do not expect any major impact impact on sales, based on experience in other countries.
Earlier this month an Imperial Tobacco spokeswoman said display bans overseas had led to an initial drop in sales, but after consumers adjusted to the changes there was "no real impact".
While the move might not see a major drop in sales initially, it will, in my view, have an impact over time.
Taking away the tobacco displays behind the shop counters means young people will not have to look at lines of cigarette packets when they walk into a shop. "Out of sight, out of mind," as they say.
In my view, anything that stops young people from taking their first puff of a cigarette has to be a positive step.
I've managed to quit for short periods of time, but have always ended up back at the shop asking for another packet. This usually comes after I've told myself one more smoke is not going to hurt.
Any smoker who's tried to give up will tell you that one of the hardest things is walking into a shop and seeing the tobacco products you crave sitting behind the counter.
Leaving the shop without buying a packet often turns into an exercise in willpower. Hopefully this law change will also make it easier for people to give up in the future.
