I dont have bad experiences with marijuana, I just cant stand it, but that doesnt make me to condemn it.
Salvia is nice but it need to be concentrated the often you take it. I dont know, if its the same like that Sativia you are talking about.
Concerning the flavours, when I go out and buy drugs on the street, I am really not able to choose a flavour. I just get the shit thats there. And looking at some old friends, who are doing the thing for like 10 years now, I know where its gonna lead.
Of course you can order blends or drive to holland from here and take it there, but its a huge logistical undertaking to do that, if you dont want to get caught.
I lived without dope for a long time, then I lived for 5 years with it and today I live without it again. Thats all I am gonna say on the topic.
