1. Smoke less. I had the paranoia and uncomfortable feeling problem for a long time and eventually I learned to just know when to say enough. In a group setting people tend to smoke a LOT, because some people have really high tolerance. I usually do a few puffs and then I'm good for a few hours... and then I eat some food, pass out, and sleep like the dead until morning. It is GREAT.
2. Go for strains with lower THC and higher CBD content. CBD is what produced the relaxed feeling and is in some clinically-approved drugs.
OR, don't smoke! I personally enjoy it but to each their own.
