Whether it\'s alcohol,nicotine,THC,caffine or chocolate.
In RL I don\'t use alcohol,does that mean I am offended by the ingame use of it? NO!
Personally,I like the idea of pipes,not because I smoke,but because if you look at the classic fantasy works,they all have smoking and drinking(name one classic that doesn\'t have at least one smoke-filled tavern scene or wizened Mage having a pipe whilst contemplating a problem). Also, if you look at history,we humans have been breathing intoxicating smoke for a long time..the Egyptian Preists burned a mildly halucinogenic incense in the Temples..it made the commoners easy to manipulate,easy to invoke \'visions\'.
As far as ingame intoxicants go,well you already have Ale and if you do not include some negative effects (even if only temporary,like lower agility/lack of coordination) then you may be sending a mixed message to the younger folks....AND, if there is no effect ...whats the point of even having it?
Now lets look at stimulants,as might be used ingame.We can use something like coffee,giving a temp increase to alertness and/or reflexes if used in moderate doses but a decrease in concentration/coordination at high doses(try it yourself..slam a half-dozen Espressos and see if you can concentrate

)
The way I see it NOW is the time to discuss this issue in a rational manner,NOT after release, so as to give the Devs a fair amount of time to consider their options.
Now... I\'m probably older than most of you,heck probably old enough to be some of you\'alls grandpa.I\'ve been computing since before all these cool 3d graphics (VIC-20 anyone?) and this is not a new issue.People my age may recall the huge stink that Duke Nuke\'m created with the strippers and the use of the term \"Aw,shit\" when he stepped in a pile. I know, not exactly the same..but as far as \'Those Who feel it is Their Duty to save us from ourselves\' see it,it is.
