Answer:
1) The price of cigarettes will be too low and quantity sold will be too high
Explanation:
The fact that so many people suffer from lung cancer directly associated with smoking, either first hand or second hand smoking, means that too many cigarettes are being consumed. Since too may cigarettes are being consumed, that means the price of cigarettes is too low. The only way to reduce the negative side effects and costs of smoking would be to levy a heavy tax on cigarettes. That should increase their price so much that eventually the quantity demanded should significantly lower.
