The more I do, the more I want it(at the time, so a binge) while the less I do, the less I want it. I say at the time, because the more I do also makes me do less over time, because tolerance and it becoming old. I like being high, whenever though. Really does not matter, it could be all the time or only sometimes or on occasions. At any event and basically in any situation(for Marijuana that is). I see nothing wrong with it so there's no desire to ever really be sober but breaks are a MUST or else your mind will be fogged and you start to lose reality.
As for actually not caring what I get high on, that only ever happens after a binge(long periods of use) and not having any. But never to the point of actually doing it, common sense always get's the best of me. Not to say I have never given in, in the pass, but being young added with prohibition and no job will do that.
Eh, experience really get's you passed all the major BS drugs can bring.
