To mix nic, isn't an easy task and some recipes could be very dangerous. I prefer mixing already made carts for more secured and more fun. the avalanche in flavors is just so unholy and alien. My preferred mixture this couple of month is
Sunset sherbet, stiizy, Pax era. I just Buy THC carts online and add them up as follows; 0.25g stiizy, 0.25g, Pax era and 0.5g of sunset sherbet for the blast. I could substitute the sherbet with heavy hitters.
