Bad reaction to smoking?

🕷

So I don't smoke very often.

Yesterday I was with a group of people (that I don't know very well) and we were passing around a joint. I took two hits off of it.

About a half hour later, I blacked out twice.

Had a panic attack immediately after I woke up from my second black out.

Then fell asleep on a strangers couch for three hours.

This has NEVER happened to me before.
