if you haven't already you might research the difference between CBD and THC. THC induces anxiety and some mania/paranoia, as well as tachycardia (fast heartbeat) . CBD does the opposite. It's difficult to get CBD rich strains outside of Cali, but if you can find Hash that's the way to go, otherwise you might try and get your hands on trimmings or leaves and mix it with your bud when you smoke. leaves have more CBD. Indicas have more cBD than sativa, but not necessarily that much.
