This is a classic example of tolerance, where an individual needs to consume larger quantities of a substance to get the same effect. In this case, Blake needs to smoke more marijuana to achieve the same high as before. Withdrawal refers to the physical and psychological symptoms that occur when a person stops using a substance to which they have become dependent. Dopamine and serotonin are neurotransmitters that play a role in the reward pathways of the brain and can be affected by substance use, but they are not directly related to the phenomenon described in the scenario.
