If the purchase and sale of a currently illegal drug (for example, marijuana) were decriminalized, economists would expect
a. an increase in demand and supply of this drug.
b. an increase in demand and a decrease in the supply of this drug.
As the tastes and the preference of the customers for the particular product increase in the demand of the sale and the purchase of the illegal drug will rise up.
As explained by the economist is know as what is called as the shift in demands and supply of the drug tends to rise in prices of the drug.
