coke and heroin are a dead end avoid them at all costs i spent 17-18 yrs addicted to both and it took 7 yrs in a methadone maintnance program and countless pounds of weed for me to quit not to mention losing my home and family and kids and spending time in jail and prison just because you can take it or leave it now dosnt mean you will be able to do that forever ask any one who has had a habit they will tell you stay the fuck away from that stuff it will kill you if your lucky if your unlucky you will spend the remaining yrs of your life chasing it or in prison
