dont you realize its just a design, The e pill doesnt have a different effect if it has a diffrent picture on it. Mabye your brains are too fried to understand that though.
Whose brain is fried? Each different pill certainly does have a different effect, not all ecstasy pills are created equal.
Those that do contain MDMA have it in different dosages, those with a dose just a tad higher can be all the more powerful due to the dose-effect curve of MDMA. There are also other related substances such as MDA and MDE with effects similar to MDMA, they don't tend to be as great though some people still enjoy them.
