Hi I am from India,21 male,I've been smoking marijuana since two years but recently I decided to quit smoking weed after a weird incident.That day as usual we bought Cannabis Indica.So I took only two hits of weed using a bong.For a moment everything was all right but then hell broke loose.My head started paining,the pain was like small hammers hitting my skull from inside and slowly the pain started to shift downwards to my legs and it was not just once I almost suffered waves of endless pains.I started shivering badly and suddenly I stopped shivering.I tried to talk properly but couldn't all I could do was rasp or howl.I shouted wildly whenever anybody tried to play any music or even made any sound because I felt as if the sounds would hammer me to death,I couldn't even resist the sound that is made by the blades of a ceiling fan.And the worst feeling I got was as if someone was driving thousand pins at a time through my spine.I tried to sleep but couldn't due to the feeling of intense pain and agony.One of my friend offered me water and while drinking it I felt as if the water going through my throat will rip my throat open.My friends were terrified as I was rasping,howling all at a time.Next day my friend who was there with me described that I was really behaving like some wild animal that day.My overall feeling that day was like a mix of aggression,pain,helplessness and by aggression I was just way out of control,the pain,that hammering feel in my head just drove me mad in anger and agony.I just have no idea what happened to me that day.So I sincerely request anyone who has some knowledge about these weird problems to help me.
