TweetI grow only "Landrace" sativas, South African, S.E. Asian, South American. But I notice the Indica's give me more of the sativa effect ? I figure things get really depressive around winter so why be "couch locked" right ? I like being active and motivated. you cant find any old skool strains anymore, everything is so inbred and crossed with so many different strains you don't get an actual flavor, taste or effect. kinda' like the beer nowadays, "wtf am I drinking ?". I'm battling a lot of depression everyday and bud really helps a lot. It gets my mind off the negatives,.. really. It's like I move on to something else ? Kinda' like you mentioned about y'all in the gym, some kind of different zone or focus you get into. as far as lungs go ? I've been tokin' since the seventies, and at 51 I passed a Blackbelt test. I'm keeping up with teenagers. but, I will bet they aren't as healthy if I haven't.
