Working on the Navajo Reservation as a Shaman, I seen 1st hand the effect Pot has on people, and it is not pleasant. Modern Pot today, is much stronger than it was in the 70s and 80s. Thus it is more damaging and quicker at damaging higher brain function. Best to quit while you can. Don't worry about not being accepted. You will find other friends who are not users, and they will be much better friends to have.
