How To Cure Heart Burn,throat Pain And Cough Due To Intake Of Cocaine?

iv been a social (weekend user) of cocaine for about 10 years, rarely coin more than 1gram per night,maximum 3 nights. I'm only 26 so i know i fell victim early and is an addict to the drug. But every other aspect of my life is positive,I'm intelligent and has always been a hard worker..i have an hour a day in the gym 5 days a week,taking full advantage of spa facilities.(sauna etc.) ah I'm also at the stage where i smoke weed on a daily basis,not much maybe 5 splits a day,again has no impact personally and i actually make a point of been more active than people who dnt smoke..suppose makes me feel a little better because i hate the fact I'm probably getting to the age,stage where it is going to catch up with me....i cough a lot which is hurting my throat and over the past maybe 1 year evrytime i go out and start drinking and take a line of cocaine, theres a constant feeling of air,wind in my stomach, as i release the air(burp) as the air come up a burning gassy pain starts in the middle of my chest,very uncomfortable and will leave the feeling of something trapped in my throat which leads me trying excessive throat clearing which just causes more heartburn, what is this and is it something i need to seriously worry about...thankyou.
