I smoke regularly i need to clean my lungs, is there a procedure and how much does it cost?

Not really.: There is no 'procedure' to clean your lungs. The very best thing that you can do for your lungs is to stop smoking. This will also save you money as smoking is expensive! if you have concerns about 'cleaning' your lungs and about smoking cessation, go to a local clinic and discuss your concerns with a provider / doc. Medications, hypnosis, and behavior modification may help. Be well!
