addictive: yes....this depends HEAVILY on the person and use
For me, i was and i say was addicted to weed, pot marijuana, chron, bc, kb, skunk, cease, bud, tree,, whatever u call it for a while. I got in some truoble and quit for a while....i still smoke occasionally(a few times a month) and since i know all the ways it can control my life i dont find the urge to be high 24/7.
The highs now only seem to make me tired whether it be indica or sativa(sativa i get tired after the high). I was mentally addicted for the reason of not being able to cope with reality without being high. Now i jsut find better things to do and dont worry about being high all the time.

My point to this thread basically is that life can be really fun if all ur days arent spent being high and that when they arent then the addiction isnt going to be there. Some of yall wont know though unless u give it a try and NO im not knocking on the peeps who are high 24/7 im jsut saying it grows tiresome when ur life revolves around a plant for a long time....keep it a part of your lives but dont use it too much.

-peace
