This is hard to answer. When I was a kid I remember smoking real Thaistick and Lamsbreath(what it was called near me I know it is called bread but breath sounds better) Acapulco Gold, Real Skunk that smells like an actual dead skunk. But what sticks out for me is back in the day around Christmas in New England these nice red haired greenie green triangle Christmas tree shaped buds would make their way around and we just called it Christmas Bud or just red haired sinse. It was good locally grown freshly harvested nice round nuggets that smelled like new carpet and gave a nice happy up laughing high, loved it and wish I knew what it was really called so I can get it again, I am searching though.
Of the strains I have grown so far the most enjoyable happy high has to be from Pineapple Express. It is the most consistent high with no tolerance build up for me even after smoking it and only it for a whole month. Every morning 2 puffs and baked with that nice droopy eyed grinning happy high.
