What everyone else already said.
I went from heavy use daily in my teenage years, toking with friends having a good time, to the point where a few puffs would make me lose my shit completely, when toking around others.
ATM, the only utility i have for cannabis unfortunately, is an occasional introspective psychadelic at anything above threshold dosages. I do not smoke around others at all pretty much anymore. Could be underlying issues though.
Whatever you do, don't look for something to take the edge off the anxiety so you can enjoy toking, at least on a regular basis. Habitual Benzo usage to self medicate cannabis anxiety in social situatinons, by far, was prob one of the stupidest things i ever did. You can try mixing other things with it, but at the end of the day, if you can't enjoy it alone, perhaps you need to re-examine your usage habits, and take a good t-break.
