Lsd doesn't alter ur chromosomes, thats total bs, just more propaganda from the gov. They did a test where they put huge doses of lsd directly on cells, and the control substances (asprin, and caffein in think) did more damage to the chromosomes than the acid did. Besides, when its taken, its taken in far smaller doses, and never does any significant amount ever come in contact with any one cell, like it did in the experiment.
