The first time I ever smoked weed I was with some friends and had a joint to my self, I took 4 or 5 hits from the joint and felt nothing at all and carried on taking hits, then we began to walk to a nearby party and from that point on I basically black out yet I was still walking, strange I know. The next thing I remember is coming back to reality in a very scared state, not recognising anything or anyone around me and feeling very confused, not even knowing really who I myself was. Slowly I began to remember what was happening and became used to it. Fast forward a month or so and me and my friends decide to try weed again, this time I'm careful to only take a few hits, this time the high is gradual and kicks in after maybe 15 minutes but has similar symptoms as before, I begin to faze out slightly and everything becomes jumbled in my head and I begin to forget my surroundings. I've tried weed a few more times after this with similar symptoms of not recognising the park I'm in or the people I'm with, most recently I took 3 hits from a joint and felt nothing for 30 minutes roughly until a massive high kicked in where I felt out of my mind completely and terrified whilst also beginning to forget my surroundings and what was happening. Can anybody help explain to me why I'm having such extreme effects from this weed and if this is a sign on soemthing bad.
