First tin to note is dt the game of addiction dosen't just start,its a mind game and should be tackled in such regards...it is virtually impossible to change people.."virtually"...and is always best that d zeal for change dosen't spring up 4rm dose around us but frm within..we don't necessarily have to hate who we currently are..we only af to see d good in wt we ar changing into for sustained change..the best possible way to put off bad habits is to feed on good habits...if u are attracted to sometin,u are invariably distracted from another thing..to distract him from smoking habits,u should attract him to not-smoking habits....d act of monitoring him,checkin his pockets for weeds,restricting his financial base and access to these things(weeds) only serve as reminders to him and increases his desire for more...if u tink u changed him,u only made him up 4 high service..u changed him 4 urself...so he probably wouldn't do it around u...dosen't mean that is same wen u are absent...all u need do is always feed him wit less talks about wat he is doing(i.e smoking),y he shuldnt be doing them and more of what he actually should be doing (such as whr his peers are,his nearest and farthest future plans,his dreams nd goals.e.t.c...it is on this note assumed that u know thhis person very well)...all this would help steer that indepth man outta him..these actions will though not directly stop him from smoking but could serve as distractons from it..(that is,attracting him more to his "fons et origo"source and origin..who he always wanted to be b4 he started smoking)...thru all this...always remember that "the chances of changing people are slim because we all have 'will'..but we can help dem see reasons to change and assist them in the road walk"
