Then it's a straight General discharge without classification. Damned lucky to not have it been Other Than Honorable, which would have royally screwed your life in many ways. An unclassified General was probably the best you were going to get then and far better than what a drug-related discharge with an Article 15 would get today.
With the Article 15 for drug use prior, it's going to be damned unlikely to have the service record changed to move that to General under Honorable Conditions.
You're looking at Open Carry, or No Carry, as your options for lawful carry from here on out.
America needs to understand that our troops are not 'disposable'. Each represents a family; Fathers, Mothers, Sons, Daughters, Cousins, Uncles, Aunts... Our Citizens are our most valuable treasure; we waste far too many.
