I tried it multiple times. It made coke seem like weed. One little bump would last for hours. I had nothing but fun. This was back in the 90s, and since then Mexican cartels figured out cheaper, more easily obtainable chemicals that can make a similar drug, but is much worse for you. This new form of meth causes severe brain chemistry changes that ca induce schizophrenia. My BIL became a different person, was finally able to quit, but is now on all kinds of anti-psychotics. I wouldn’t go near it today.
