I'm not sure what that 300% tax rate refers to specifically, but isn't it pretty much similar in the US and Europe? For instance, when, say you pay $12 in New York City for a pack of cigarettes, about $8 to $9 or so of that is different taxes (local, state, federal, etc.). So you're paying about 3 times more in taxes than the price of the actual pack of cigarettes.
I remember around 1997-1998 (when I was still living in NYC) the price for cigarettes started dropping. It went from average $2.50 to $3.00 a pack down to $1.50 to $2.00, although getting it for $1.50 to $1.75 was easier to find just across the Hudson River in New Jersey. I had a friend who lived in Fort Lee just across the George Washington Bridge and my parents lived a couple of towns over, so I used to drive across the bridge often to visit and get cigarettes at a gas station for 1.50-1.75 a pack.
Someone told me at the time that the tobacco companies were reducing the prices as the governments were increasing taxes on them so that the price stayed the same or was even going lower. When I left the U.S. in 2006, for the last year or two, a pack was around $4 to $5. I've heard recently from friends that in NYC and also in Boston area a pack is from $12 to $15. It's really outrageous no matter how you look at it.
Meanwhile, local pre-rolled cigarette brands in my country are about 60 to 70 cents U.S. a pack and they've gone up in price recently. They used to be about 45 to 55 cents.
