From my experience, it doesn't happen 'a lot' but it does happen.

Obviously we cannot tell you whether or not its all in your head, because we don't have enough information. But, IF it really is in your head, that would not be abnormal. There are plenty of people who have panic, anxiety, and overall discomfort issues with smoking marijuana. As Washougal hinted, try some different strains and see which is more comfortable for you.

Worst comes to worse, there's no harm in not smoking and drinking. :jointsmile:
