All I know is when doing this you need to make sure what you're doing doesn't have any other dangerous things in it. Acetaminophen (Pain Reliever) is in a lot of the same medicines that contain DXM. As we all know, too much of that is terrible on your liver, and liver damage is a big deal. The safest and most fun way to trip on DXM in my opinion is Delsym. Drink 2 full 6 oz bottles of Delsym - 12 hour cough relief. You will have a lot of fun. I never got sick from it. An unsafe way but more intense way to trip on DXM is of course, Triple C's. Coricidin Cough and Cold. You can do an extraction on these pills to remove the Acetaminophen, and since it's HBr, it will make your trip/high way more intense than Delsym. Be safe, don't do unintentional damage to yourself. Have fun, hope I could help.
