And the correct answers are: Decrease/oppose.
Step-by-step explanation:
To begin with, in the microeconomics theory when it comes to concept of substitutes it refers to the relationship that exists between two goods that are similar in characteristics and therefore that they are probably to substitue one for the other in the market in the case when one's price is higher that the other. That is why that in this case presented, the legalization of the marijuana would obviously lead to a decrease in the demand of the cigarattes due to the fact that now the consumers will start to consume more of the other, letting the cigarette fall. And therefore that the distributors of cigarattes would likely be oppose to the legalization because it will affect their business.
