Steven Tyler & Sheryl Crow to Play CT Organized Addiction Rally in D.C.ERIK OFGANGGreg Williams was 12 when he had his first drink.The Newtown resident had snuck into a liquor cabinet owned by one of his friend’s parents and as soon as he tasted an alcoholic beverage, something clicked. “It did something for me,” he recalls.Soon after he was smoking pot and by the time he was 15, he was using prescription drugs. By 17, he had developed a full-fledged addiction to Oxicontin and other opiates.This was almost a decade and a half ago when heroin did not yet have a major presence in suburban Connecticut towns like Newtown, but Williams has no doubt he was on the road to heroin use. However, after a near-fatal, substance-abuse-fueled car crash when he was 17, Williams got treatment and got clean. Many weren’t so lucky.
