what color smoke?

blue = oil burn (not good)
white = coolant burn (not good but not as bad as oil burn)

you could also be burning your clutch but you would be able to smell that

white smoke how could i solve this

check your coolant level

could be simple as a hose leak or your radiator could be cracked

if you don't work on your car take it to a shop

Ok, this might sound funny, but do you smell an almost "sweet" smell? This is kinda like antifreeze.

Got a question for ya. Does it happen only when the engine is hot or when you first start it up?

only when its hot and usually when i done shift then hit the gas

do a compression check...the guage cost about 25 bucks. disconnect your fuel pump fuse or relay (so the motor won't start when you crank it). pull one spark plug at a time and screw in the guage. it helps to have a friend here crank it over so you can watch for "ticks" on the gauge. count 5 "ticks"or you can just crank it yourself and go look at the guage. all eight cyliders should be around 150psi. that will tell you if you popped a head gasket or burned a ring/pistons. basically it'll clear up the worst case senarios. otherwise it could be an lower intake gasket (coolant) or valve guide seals in the heads (oil)
