Okay, I have done Adderal which I consider speed. I took it, it was a capsule. If gave me some amazing effects, I felt fast, I had to be doing something, cleaning a house, smoking a cig, just anything i could do, i had fun. Lasted about 10 hours. My brother told me about he did speed. It was a pill form, he said the pill was so small he didnt feel it go down his throat, he thought he dropped it. Although he said it lasted 20 hours, he said his heart beat so fast he is surprized he didnt die. He said it made him feel out of breath and tired, only worst then ever before. He said it was so bad he was ready to wake my parents for the emergency room. He said was the most miserable time of his life. Who had the real speed? was he doing a stronger kind or what? Im confuzed. My bro said the guy who gave it to him said it was speed and before he took it asked if my bro had heart conditions.
