Make changes in your environment that will discourage target behavior and encourage healthier choices.

Answer with Explanation:

If my target behavior is "smoking" then I'd suggest to ban places which allows smoking areas. This is a very effective way in order to address the behavior. People who violates this law will also be penalized and if they continue to violate it, then they will have to be brought to court. In such way, smoker's attention will be diverted to healthier activities. Instead of smoking outside, they can go jogging in order to relieve themselves from stress. They can also spend quality time with their family.

If they practice this every day, then it will gradually become a normal part of their routine until they totally give up smoking.
