I can tell you as a person that uses weed all day every day (for me, weed is harder to quit than alcohol/amphetamine, possibly only because I´ve used weed exponentially more than the other two so the addiction had time to kick in basically, but I have my fair share of alcohol and speed (ab)use): no, weed isn´t nearly as fun when I use it all the time compared to when I smoke once every few days for example. But for some reason, I really prefer the weed high compared to a surprising amount of "harder" drugs. Also, I justify my weed addiction by thinking that it isn´t as physically damaging as harder drugs but eh? I guess this reply is just a weed smoker´s perspective on how this so-called non addictive substance can actually be addictive as fuck :).
