I have been smoking blueberry for 3 months straight. My friend grew some DJ Shorts BB and it used to be so killer for me, it would take a joint for me to get crazy blazed....Tonight me and my friend smoked 8 fat-normal joints and 2 blunts and I am about as high as I used to get off of a joint. Switch strains every two weeks or so because you can be really tolerant to one strain. If all you have is that one strain to smoke take some 5-htp before smoking and it seems like it lowers tolerance and inceases visuals in you high.
