the first time i smoked i didn't get paranoid at all than it gradually got worse from there but than i learned how to turn it around and now i rarely get paranoid.

also don't smoke unless you want to, smoking in tight situations gets you paranoid

here are things you can do:
1.first acknowledge that your excited and you are high and its just a lil weed and weed has never killed anybody
2. if you have eyedrops use them cause i know someone telling you your eyes are red can very easily make you paranoid.
3. go to an area that you consider to be safe, that is away from any real danger. for example i try to go to someones house or a park and only be around stoned people cause i get a lil nervous around sober people.
4.(this doesn't really help paranoia but i'll add it) look up and if you're with people engage in conversation i have realized everyone looking at the ground, not talking gets awfully suspicious.
5. think about someone you love. i think about a special girl and it helps a lot. also try thinking about food and how good its going to taste when you get some. also eating makes everything good again, duh.
6. don't think about you body or feel it if it hurts its very easy to convince yourself theres something wrong with your body when your high.
7. try not to feel guilty under rare circumstances about anything, let it go until your sober.
8. masturbation< works really good
9. if all else fails its time you check into your bed cause you will wake up perfectly fine
