We need to be careful to be accurate when we can.
This is simply not true that "spice" is strong pot (marijuana). As most people know typical marijuana (or pot or weed) is a real organic leafy plant that contains varying levels of THC which is the incredient that causes the "high" in people. Some states are legalizing it for medical use and even some states like Colorado have legalized it for recreational use.
"Spice" or "Incense" on the other hand is a complex man made synthetic compound which was made to mimic the effects of marijuana and get around the laws, however, due to its varying uncontrolled chemicals and mixtures with other substances, it has been known to cause terrible reactions and serious physchotic episodes in people. It is very dangerous and it is being outlawed in many states at this point. When it first came out, some blends were sold in gas stations and head shops.
Just wanted to be sure we have accurate information and the below link of information gives much more detail on "spice". I am glad it is for the most part banned in lots of states now.
Also, "bath salts" is not "meth" as they are 2 entirely different things. They are both very dangerous of course, but they are also both very different.
