I don't trust people neither. I think it's quite ok to be a bit paranoid. You need to know who you are and what you want. I'm sure there are people you trust. Stay calm, do your job. I smoke for 9 years, the beginning was great, then I had to adjust my behaviour to the new (stoned) me, to learn to deal with the time perception etc. It is good fun to be able to see the reality both sober and stoned and compare these states. Im not taking about paranoia, am I?
