hey ollie,
i also suffer from anxiety while smoking weed,it caused me to quit for almost a decade.
anyway i still get the occasional anxiety attack but im finding for me cannabis is becoming a spiritual/meditational activity.
how that affects my use is i only take between 1 to 2 hits then im done
my attacks are seldom now and i have xanax on hand for when they do.
also the above posts about frame of mind/strain are dead on
i stay away from sativa and avoid haze like the plague.
remember that our minds are so strong we can "talk" ourselves into almost anything even dying.
so do the opposite when your not stoned think about how and why u like cannabis and how it helps others in need.also if you dont have much control over the types of weed you get trichrome color also helps you will want amber/red for a more body buzz.
ok i hope i've helped in some small way
:thumbsup:
