A friend had an explanation for this, and I really agreed with him. The antianxiety effects of THC arrive after the initial high. The beginning is a spike of feelings that a lot of people find to be intense... and leads to paranoia and an increase in anxiety. But as this brief rush fades there is relief and a longer lasting calm.
To put it another way: after a stone is dropped in a pond the splash is a mess, but the ripples that follow sure are pretty. :)
