starting up smoking again (mflb Question)

So after a one year break I am smoking again  ! Not sure how I went that long, it sort of just happened. Anyway I have recently enrolled at Tafe for a 1 year course and figured why not spark up again the timing seems right.
 
So 2 days ago I stumbled upon this great little contraption called the "Magic Flight Launch Box" and while I have always trusted my bong for many years I think I want to give it ago as many people say its great! But do have some questions if you fine people could help me out, that would be great.
 
do you think I need/should dry out again before getting into vaping? I was dry for a year but in the last month smoked about 3 quarts not really sure if that is enough I felt I was building up resistances but nothing like before...now 2 (half) cones get me pretty damn high.
 
do you think its possible to quit smoking and vape? its financial... 100 bucks for weed a week and 100 on smokes (damn you Australia) starts to put dints in the wallet fast. I want to save but smoke weed so I figured I can drop smoking as I have been meaning to do it for a long time but had no real reason until now!
 
Everyone is different but I am looking to find out if it really does stretch the dank or not, it does say up to 4x longer, if that was the case 100 for a month would be great but how did you guys find it?
 
If I was to be totally honest with myself I would probably end up smoking every night about 3 cones or 4 (half size) and be totally happy with that. Just wondering with this in mind is do you think this product suits me?
 
 
thanks for your help
