Hi, im am 21 year old. day ago i smoked weed, which was very strong for me, since i havent smoked much in past. After I smoked, my head got very numb, n I got very scared. My heart started racing and I tried to controll the numbness, but i felt the more I tried , the worse it was. My sense of direction got worse as well as my movements. Today, even after a day I can feel my head differently, as its still numb , and something is happening in the back of my head, Im afraid it damaged brain blood arteries. Can you tell me if this is going to go away, because I feel like Im gettin paranoid and causing such feeling...
