It's so difficult to answer this as everyone's experience will be different. I do know that there were certain periods of my life where I didn't smoke pot because I was just very active with something or the other and did not want to be lazy. But I was probably using an upper during that time to "be productive". There's also got to be some kind of chemical/medical aspect to how a certain substance affects you individually, apart from how it affects everyone else. I was more of a cafeteria drug user and got bored really quickly and the only objective was to be high(or low), not necessarily an obsession with one kind of drug. For instance, heroin withdrawals were never stereotypical for me. I'd always thought of it as a high wearing off, and would fix it with any other drug that was available, it didn't strictly have to be heroin.
