Its all about your general mindset in the act of smoking and being high... the more you do it the more youre comfortable with it... i used to be very afraid of being in public places stoned, and after a few months, it not only is easy for me, but i do it all the time. im stoned most of the day anyway lol. just go into it with a good outlook, and if the shit hits the fan throw the pipe/bud and run.
