Any drug related charge is a problem regardless of how long ago it occurred. Even if it was under the age of 18 and sealed. A friend of mine had been charged with possession some 30 years ago and he was under the age of 18. The case was supposed to be sealed,remitted or something to that effect. But when he went to gain his purchaser's permit for a firearm was denied. After weeks of phone calls to the Michigan State Police and several visit's to his local judge he did finally get it remedied. This is an instance where regardless of what the Law reads, LEO's and Elected officials can make it difficult to say the least. Mind you it was a marijuana charge which the amount was a misdemeanor.
