That the spice products are called (legal) "fake weed" gives them its appeal. How bad can they be, if it's legal? Yet, in almost every single case/product, no one can tell you what chemical were used and/or what they do to the human body. Think about that...we have an unknown chemical ****tail sprayed on whatever it is to light it on fire (i.e. consume the chemicals) and no one knows what they are. Please be reminded that the "bath salts" that are oft sold by the same suppliers are/were legal, as well.
I know a guy who owns a few smoke shops. He sold that stuff when it was legal...made a fortune; accounted for most of his income! In fact, gas stations that sell the stuff were making more in that stuff than all of their other products. That's because people get hooked and keep buying it. That should tell you something...it's addictive. And no matter how many times a specific chemical in the current batch was outlawed, the manufacturers has another substitute lined up. FYI: in many cases, the old product had to be swept off the shelves and chucked.
So, people can refer to it as fake/synthetic weed, but it's just a chemical ****tail of which no one really knows what is contained, as they keep having to change the recipes.
Many get into this kind of innocently because they believe that if it's legal, it must be OK..can't be that bad for you. That's bunk! The truth is, people have not gotten wise to what's going on under the proverbial covers. This stuff should be banned everywhere. It's not "fake" weed! It's a mess and many people are fooled by it being displayed at gas stations, etc...
