A sour patch kid is a type of candy that is made with sour sugar. The amount of sour sugar in each candy varies, but the general range is between 2-3 grams. Most edibles contain 10-20% THC, so a rough estimate would be that a Sour Patch Kid edible contains somewhere between 200 and 600 mg of THC. However, it's important to remember that THC content can vary widely from one edible to the next, so it's always best to start with a low dose and increase gradually as needed.
