I guys yesterday I got a new sativa dominant strain called great shark, I was so excited and happy because I'm tired always felling sleepy when I smoke weed. Finally I go yea sativa should energize you. Anyways I tried it after 20m I felt so sleepy I couldn't open my eyes they were small open. I smoked 0.30g joint in total, how is it possible I feel sleepy to a sativa? Could it be it has nothing to do with indica hybird or sativa how the high effects you? I heard terpense are what responsible of the affect of weed give you. My weed had myrcyne terpense, wich this terpense makes you verry sleepy. I finally found a strain with no myrcyne headband wich has limonene terpense wich is the terpense that give you energy bost. I'm not sure im confuse let me know what you guys think?
