Suppose that the government tends to maximize the tax revenue. How would the cannabis price drop affect the government tax revenue if cannabis was taxed by price? Did the government anticipate the cannabis price drop when designing the tax scheme? You may come up with an artificial numerical example to support your findings. are alcohol and cigarettes substitutes or complements of cannabis?(The answer to this question depends on the actual consumption data. If you do not know the data, you may make an assumption. Then, you should stick with this assumption for the rest of your analysis. For example, if you assume that alcohol and cigarettes are substitutes of cannabis, then your entire analysis is based upon this assumption.) How would the change in the price of cannabis possibly affect the market demand curve for alcohol/cigarettes?
