I've been a heavy smoker for awhile now, and would only smoke heavy indica's to calm down my anxiety. but recently with my new meds.. I've noticed that the indica isn't suiting the purpose as well as before, so just like switching other meds, i switched to a sativa which completely changes the high and the purpose, and compliments my new meds rather that clashing with them. i really believe weed is a miracle drug, you just have to find the right one for you.
